Borax for Fleas – 3 Simple Steps for Flea Removal

Fighting fleas can be a nightmare! To make matters worse, there are so many different opinions on how to treat them that it’s probably left you rather frustrated. Perhaps you have tried flea collars or maybe even a few natural methods and didn’t have much success. While each case is different, your primary goal should be to get rid of them as soon as possible. If you have done a little research, you have probably come across many articles suggesting the use of borax for flea infestations and may have wondered if it’s a good solution. Unfortunately, there is a lot of incorrect information on the internet and as a result, I decided to put together a reliable guide that will put things in perspective and give you all the necessary info to help you make an informed decision about using it for flea control. I highly recommend that you take some time to read this entire guide and I invite you to ask any questions you may have in the comment section and I will try get back to you within 24 hours.

Is There a Difference Between Using Boric Acid and Borax for Fleas?

Despite what you may have heard, while borax and boric acid both contain an element called boron (which in small quantities, promotes bone growth and even boosts the immune system. However the difference is important! Borax (sometimes called “Disodium Tetraborate or Sodium Tetraborate on product labels”) is mined from the earth as a complex form of boron bound with other minerals (such as sodium) while Boric acid does not occur naturally in nature, but is made from borax by adding an acid such as hydrochloric acid) and water to the solution. Since boric acid contains this mixture, it significantly increases the toxicity level and you need to be very careful when using it for fleas, especially if there are young children in your household.

Borax looks very much like salt. However, this salt is NOT the type that you would use on your food but rather is a substance that can be used for killing a variety of pests and other nasty insects. The powdered form is even used in some household cleaning agents.

Does Borax Kill Fleas? How It Works And Safety Tips

Based on my personal experience and feedback from my readers, using borax for flea control really works. The powdered form has absolutely no smell and doesn’t get absorbed by the skin when touched. It kills fleas by acting as an extreme dehydrate and by making tiny cuts in their exoskeleton which results in their eventual death. It can even be used to prevent small larvae that hatch but unfortunately will not help you get rid of flea eggs. That step will need to be done separately and I will be more than happy to help you with this process after you check out my guide on this topic. :)

In fact, since borax is naturally occurring substance, it’s fairly safe for your family home. Remember that borax is significantly less toxic then most flea insecticides and products. Even though it has a low level of toxicity, here are a few warnings to keep in mind before you start using it:

  1. If you are pregnant, please stay away from any Borate substance – this includes borax!.
  2. Keep your cats away from the borax powder as it can cause terrible breathing problems and potential fatalities.
  3. Make sure your carpets are not wet (even from humidity) as this can damage the fibers and cause discoloration.
  4. Keep the borax powder away from food (especially if you have young children) as it is dangerous for consumption in large quantities. (more than 5mg) **UPDATE** I have recently been informed by a medical practitioner that anything around 5mg is still pretty safe (slightly higher toxicity then table salt). However, keep in mind that cats are rather sensitive to borax and as a result, just take it easy if you have one in the home.
  5. Keep the borax away from your plants as it can cause damage to them.
  6. NEVER put the borax powder directly onto pets, even if they have fleas. Borax is used to get rid of fleas in your home and using borax on dogs for fleas (as well as other pets) can be dangerous for their health!
  7. Don’t scatter borax powder for fleas around your home as a flea preventative because prolonged environmental contact can potentially cause health problems like skin irritation and other allergies. If in doubt, contact a health practitioner if you notice any adverse reactions after using borax in your home.
  8. Don’t use this powder if you have small children (especially babies) or young pets (unless you keep them out the house for the day) as it can cause health complications due to their small body mass and close proximity to the ground.

Borax Powder or Boric Acid Powder – Which Works the Best?

borax fleas boric acid pictureBoth of these compounds (borax comes from boric acid) work fairly well for pest control. However, as previously mentioned, boric acid is often combined with other chemicals and as a result, I usually recommend that you rather use borax powder. There are a few concerns for using borax for fleas (listed above) but it’s usually much milder (and thus safer) then using boric acid powder. However, the choice is yours. Based on feedback from my readers, I have been told that boric acid works really well for killing cockroaches so you can always test both to see which gives you better results. As for choosing a specific brand, I know that Mule Team borax for fleas is very good product that you can try.

Where To Purchase Borax (Or Boric Acid)?

I have had a number of people asking “where can I buy borax?” and have found that the easiest place to purchase it is Walmart. Alternatively, you can try your local supermarket or order it online from a reputable vender. Unfortunately I don’t sell it but if you drop me an email with your location I will try and find a local seller for you :)

How to Use Borax to Kill Fleas – 3 Simple Steps

Before you start using borax, please make sure that you have read the warnings section of this article. Additionally, please note that while extensive research and experience has been put into this article, The Bug Squad is not responsible for any adverse reactions or poor results.

Step 1: Sprinkle borax powder on your carpets and in areas where you have a major flea problem.
Step 2: Give the carpets a good brush with a stiff house brush or broom. This helps the borax powder get down deep and reach any fleas that may be hiding themselves from your wrath.
Step 3: After at least 6 hours (its fine to leave it for much longer if you wish), vacuum your carpets thoroughly, spending extra time in areas where you used borax.

It’s really as simple as that. Just remember that you will also need to treat your pets for fleas (don’t use borax though). Here is a great guide on dog flea removal and how to safely kill fleas on cats. Will borax kill fleas immediately? Not likely. But if you stick to the 6 hour recommendation, they will die.

Other Interesting Borax Uses

Besides being a great substance for killing ants, fleas, bed bugs, roaches and other pests, borax can be used to make amazing crystalline structures that are absolutely awesome. Borax can also be used to preserve animal pelts, protect and age wood and even is an important part of glass production. Recently I was sent an article about how borax can even help cure Arthritis While I cannot verify the truth of that linked article, it’s definitely interesting that such a simple compound can have so many uses.

Borax Fleas Treatment Alternatives

A great alternative for borax flea control is food grade diatomaceous earth. The application is the same as listed in the directions above and it’s completely natural and safe for your family. While borax may give you quicker results, if given the choice between the two, I will always choose diatomaceous earth and if you haven’t had the opportunity to try it out, I highly recommend doing so :)

Finally, besides using these natural flea removal tips, plain old table salt and baking soda have also proven to be a valuable weapon against fleas in carpets. Mix a single cup of salt with a single cup of baking soda and apply it on your carpets, etc. and don’t forget to rub it in. I have personally seen good results using this method and if you are on a tight budget, this may be your answer for cheap flea control.

In conclusion, does borax kill fleas? Absolutely yes! while there are a few risks for using borax fleas treatments, it’s definitely a great option for effective flea control in your home. However, it’s also important to treat your pets with a decent spot on product (such as Front Line) to ensure that you get rid of all the fleas and don’t have another generation of these pests invading your home. I also recommend performing all the flea removal tasks on the same day to ensure that you kill them all without any chance for potential reproduction between treatments. Remember that you can also make a few flea traps to get rid of them in your carpets.

    • liz says:

      simple but not always easy to get rid of fleas on carpet. this summer 2015 in California was very hot for months. 10 yrs we have never had to give indoor cat flea med, now we do. she is scabbed all over, open sores from scratching and stress doesn’t help it raises their cortisol not to mention having toddlers chase her around. we use on all 3 pets front line, boraxfor carpoets, flee traps i bought on amazon, borax for our sandy backyard, dog beds inside and out..its alot of work. washing bedding, vacuuming every 2 days flee combing, just don’t want to the the fogger! im so paranoid as a mom, but i recall my family doing it all the time in our house..
      we don’t have flees jumping on us humans . cat and one dog has them. i comb cat daily i find one or two. now gotta take her to vet for possible infection from scratching. i think i will continue this advice from YOU AND buy 6 more boxes of 20MULE TEAM BORAX for 4$ ea.
      thank you!!! good advice. seriously helpful.

      • Natasha Anderson says:

        Hi Liz, glad that I could help you, hope it works out for you!

    • phil para says:

      Can you wash your dogs blanket and pillow cover in borax………and if so is it safe for the animal?

      phil para

      • Natasha Anderson says:

        Hi Phil, it is safe but I would rather use something like DE, seems to work better.

      • lou says:

        I am fed up with fleas and I don’t even own pets. There is an infestation in my yard. Can borax help?

        • Natasha Anderson says:

          Hi Lou, yeah but its not a great option, either get a pro for your garden or do a little research on beneficial nematodes.

  2. Sally Smith says:

    Hi, really appreciate your advice, which sounds very thorough and precise. I hadn’t read about leaving Borax for 6 hours before. I’m wondering about mites. Do you know how to get rid of those? I’m not sure if that’s what I have but the bites fit that description. Either that, or I’ve developed a sensitivity to flea bites, which never bothered me at all before!

    • Natasha Anderson says:

      Hey Sally! I am very glad to hear that you enjoyed my article and I hope that you can put the suggestions to good use :) As for your mites question, I will be doing some articles on that subject but if you have bites from those, I have heard that a natural way you can ease the itchiness is by applying mineral water or a cream specially formuled for these bites (such as a sulpher cream). As for your carpets, either use a water based vacuum cleaner or steam clean them for best results.

      • Matt B says:

        If you have mites or scabies its a huge uphill battle. Its not easy to get rid of. You can mix borax and bakingsoda and use as a body scrub and also has a non-shampoo shampoo. Its will still be very rough and doesn’t lather but it does clean and keep your hair soft. Its also said to be safe for digestion by adding a 1/8 teaspoon to a liter of water and drink, it acts like a detox for your body, don’t quote me on it cause i haven’t tried it. But its suppose to prevent the mites from laying eggs under your skin and the borox on your skin.

  3. Jacquie says:

    Exactly the information I have been searching for and then some. :)
    Thank you for such extensive research on your behalf.

    • Natasha Anderson says:

      Hey Jacquie! Its a pleasure, glad you found this information helpful and thank you for taking the time to leave your positive comment :)

  4. Alicia says:

    if I am moving from one place to another, do i get rid of all furniture..because i know you can take them from one place to another?

    • Natasha Anderson says:

      Hey Alicia! No, you don’t need to get rid of your furniture! If you are moving, I recommend using borax on your couches, etc. that may be hiding fleas and that will get rid of them. Make sure that you also treat your pets as they are a more likely way that fleas will follow you to your new home. Hope that helps :)

      • Alicia says:

        I don’t have pets, and these things are a first for me. Never experienced them in my life…they are not pleasant..makes my skin have sprinkled Borax all over the floor, and was all the clothes with the Borax, however..I am still seeing little ones. I guess this is an ongoing process until they are all gone?Should I use DE as well? I have a 9 month old and a 5 yr old in my house…thks..appreciate your insight.

        • Natasha Anderson says:

          Hey Alicia! Well since there are only the young left, at least you have killed off the adults. To be honest, its not usually a continuous process if you don’t have any pets and the like. The reason why you are still seeing fleas is because there were still eggs in your carpets, etc. that have hatched (the borax wont destroy the eggs). Either you can keep using the borax until all fleas have hatched (this can take a short or long time, generally between about 2-10 weeks) or use an IGR flea spray to stop them from hatching. Hope that helps!

  5. Brenda says:

    Hi I have a 2 year old and we bought a couch with fleas we are both covered in flea bites and we live in a house with wood floor any advice please!

    • Natasha Anderson says:

      Hey Brenda, for some instant relief from flea bites (without the expense), check out my dedicated article on this subject by browsing the flea category on this site. As for the flea problem in your house, if there are tons of fleas (wherever you look), I recommend using a flea bomb and combining that treatment with Diatomaceous Earth (food grade) on your furniture (or wherever you find fleas).

      • ashley says:

        Get tea tree oil and a spray bottle add water and spray yourself and child. I also make a strong dose for the areas that have the flea issue.

        • NMcy says:

          Where do you buy tea tree oil?

        • Natasha Anderson says:

          Hi NMcy! Any pharmacy should have it.

  6. Carol Petty says:

    I have a bird also, will the borax affect him if I leave his cage in the living room (I was going to use it overnight)?
    If borax will harm my bird, how much salt would it take? I only have a small one bedroom apartment (663 sq ft)
    Thanks for all your help!!

    • Natasha Anderson says:

      Hey Carol! The borax will not affect him if you just sprinkle the borax powder low to the ground without letting it “puff out” when putting it down. Fill a plastic container with borax powder, punch some holes in the bottom and “sift” it over your carpets to ensure an even spread. Its a pleasure, I am glad that you have found my assistance beneficial.

  7. Pam says:

    Thanks for the info. I have read other articles on Borax and fleas, but yours goes a step beyond with the specific warnings. Bravo!

    • Natasha Anderson says:

      Its a pleasure Pam! I am glad that you found it useful, please feel free to ask me any questions and I will be more then happy to assist you :)

  8. susan says:

    Any more suggestions? I’ve used the Salt..the diatomacoeus earth…used both together left down for a week…used pinesol and vinegar…borax been down three days…help!

    • Natasha Anderson says:

      Hi Susan! It sounds like you also have a flea egg problem. Remember that while salt, DE and borax can kill both adult and baby fleas, it cannot reach those unhatched fleas which can often only appear much later. Before you use a flea bomb, I recommend placing the DE or borax on your carpets and then give it a good brush with a grass broom (or a hard bristled equivilant) so that the fleas become active and you have an improved chance at killing them. Good luck!

  9. Angelique Aimee Graf says:

    hey, thank you so much for writing this, im wondering if this is safe for someone with ferrets? I have two ferrets that are usually in their cage, but I need to get the fleas out and off of them because fleas can be fatal for ferrets, I dont have anywhere to take them while the borax is setting though. Im just worried about my babies!

    • Natasha Anderson says:

      Hi Angelique! It should be fine but since they are rather close to the ground, I would rather you keep them away from the places where you are placing the borax, at least for awhile until the powder settles. If you find fleas on your ferrets, just use a mixture of dawn soap and warm water and wash them with it. May seem a little strange at first but this method is fantastic and I encourage you to try it.

  10. Viola Sullivan says:

    Used the borax on my carpets but left it for two days then vaccumed. Took apart my upright cleaner and washed all the filters and housing after. Was stunned to learn I had fleas when there was no animal in the house. Do we actually track flees in our homes ??

    • Natasha Anderson says:

      Hi Viola! I presume you are wondering if humans can attract fleas and bring them in our living spaces and the answer is yes. While we are not a favorite meal, fleas can feed on us temporarily while looking for a more suitable host (like a pet). I have an article on human fleas, check it out under the flea section at the top.

  11. Susan says:

    Natasha..I have no carpets, only hardwood and I have daily used the broom to redistribute the borax and hatch those darn lil devils..I go as far as to make sure the borax is worked into every crack until the crack is full and white even!

    • Natasha Anderson says:

      Hi Susan! I presume that you are not having the expected results? Or are you just checking to see if you are doing it correctly? Please let me know so I can help you if needed. Also, make sure that its Mule Team borax, its not an absolute requirement but that’s my recommendation as it has worked very well for me. Remember that you need to make sure that you treat your pets as well otherwise the fleas will just keep coming back, I have a dedicated guide for cats and another for dogs so perhaps take a look at that :) Good luck! P.S: Sorry this response took so long, been having PC issues for the last couple days.

  12. Margaret Satterwhite says:

    Do you know is this helps to control spiders? Also send me the link on arthritis. Thanks

    • Natasha Anderson says:

      Hi Margaret. Based on my experience, its possible but since spiders are a hell of a lot more mobile then fleas (and don’t hide in carpets for example), they will have to literally walk through it to have an effect. It can be used as a proactive measure to keep spiders away but its not nearly as effective as using it for fleas. I have linked the arthritis in this article, which means you can just click on the words and it will take you to the resource. Hope that helps Margaret, let me know if I can help you further!

  13. Santos says:

    very informative and exactly what I was searching for…all in a well laid out article

    • Natasha Anderson says:

      Thanks for your kind words Santos, its much appreciated. After you have giving the steps outlined in this article a try and need some additional assistance, please let me know. Cheers!

  14. Robin says:

    I went to the store and am currently putting it down on rooms not used as much by my kitten.I plan on bathing the kitten tommorow and after cleaning up a room from the borax residue I am putting her in there and finishing up the rest of my house.I have only piece of furnature as I am moving and of course its where i sleep and it is full of fleas.I sprinkled borax on it today as well as my car because I live in a sandy area and have cats outside.I have bombed the house 2 x now so praying this works! Thank you as your articles were by far the most informative.

    • Natasha Anderson says:

      Hey Robin! Sorry this is a bit late but I am sure that you had success with your treatment. Your steps are good and I am confident that it went well. If you are still having any flea issues, please let me know and I will be more then happy to assist you. Also, thanks for your kind words, I really appreciate them :)

  15. jenny says:

    Hi , thanks for your article. Very interesting !
    I’m pregnant and I use 20 team mule borax to clean the kitchen sink or the bathroom, etc.
    I don’t wear any protection as a mask or gloves. I read in your article to stay away when pregnant.
    It looks you know well about this product.
    Do you think it can be dangerous for the baby when pregnant if we breathe when we use to clean ?
    Thanks a lot for your answer. Best regards

    • Natasha Anderson says:

      Hey Jenny! Its an absolute pleasure, glad you have found my guide beneficial. Borax is a powder that contains borates and thats why its shouldnt be used when pregnant as it can be dangerous. I recommend using DE (I have an article on this) as its a safe alternative and works very well. Good luck!

  16. susan says:

    I believe I finally conquered my flea situation…I read on another site where someone else used the borax on hardwood floors with no luck, thought due to borax wasn’t fine enough to penetrate. Thinking on that line, I put borax in my magic bullet in small batches, till I did get a finer powder…applied it and tedious as it was rubbed it into floor cracks and crevices by hand…left a couple days …vacuumed up and ….NO fleas and its been about a week I believe!
    This after the DE, pinesol, vinegar, Murphy’s wood oil soap, etc was the answer for me on my hardwood floors! Hope it helps.

    • Natasha Anderson says:

      Hey Susan! I really appreciate the fact that you have taken the time to share this with me and this community! While I have used DE on hardwood floors in the past with decent results, based on your experience I think its safe to say that borax is more effective. I will definitely convey this to anyone who is in a similar situation and I am glad that you have finally got the flea problem sorted. Thanks again!

  17. Meeshell says:

    Yes Yay! Only found 3 fleas, no more on cats/kitten 3 on me. Spent $$$ doing all pillows, rugs and bedding in house at laundrymat yesterday and vacuumed the DE up after I had it sitting for 3 days!

    • Natasha Anderson says:

      Hey Meeshell! Awesome stuff, I am sure that after a few more applications of borax, you will be completely flea free. If you are still battling after a couple days, please let me know and I will help you personally :)

      • Meeshell says:

        :( I still have fleas… I guess more DE tomorrow, it has been a week tomorrow. I left it on for a few days but we caught maybe 50 all on Fritzi, my kitten. It has been so hot here and they are everywhere outside. I hope I get ‘em w/next application… I will keep you posted.

  18. Mary Rounds Tagliarino says:

    I had thought I had fleas in the carpet around my desk but it turned out that they were “Little Fire Ants!” Apparently, they exist in some of the southern states (I am in FL) and can get into houses and live in carpets and even bedding… Google them. They are only 1.5 mm long – that is just a bit over 1/10th of a cm. No wonder I could never see them or find them. Another clue that they were ants was that I was only bitten at night, which is when ants are most active. I used a commercial ant bait and put a small spoonful behind my desk which has massive drawer units and is only an inch from the wall… so my cats can’t get back there. Within 3 days, I was free of the little devils! I couldn’t believe it! I also sprinkled some 20 Mule Team Borax close to the baseboard near the desk for a long-term solution.

    • Natasha Anderson says:

      Hey Mary! Thanks for sharing your experience with us, I really appreciate your input :) I havn’t had to deal with that type of situation before but thanks to your comment, now I do. I am sure that there will be others that will also benefit from your advice in the future. Cheers!

  19. Duane A. Couchot-Vore says:

    Excellent article and very helpful. However, as a chemist, I was skeptical of your 5mg figure under toxicity and looked it up. Mouse LD50 is 2g/kg, which makes it a bit more toxic than table salt. I wouldn’t be flippant with it, but you can assure your readers that it should be quite safe to work with. I’ve seen some comments about risk to cats. Cats lack some of the metabolic pathways of most mammals and so are more sensitive to many toxins, so caution should be used.

    • Natasha Anderson says:

      Hey Duane! Thanks for your positive remarks and for the excellent advice, your expertise is welcome here at The Bug Squad! I have made the adjustment to the article so that others can benefit from this additional clarity, thanks again!

  20. very worried says:

    Is DE or borax more effective on hardwood floors? How long do I leave it on before I vacumm? I also have 4 cats treated with advantage II and live with a person with heart/lung condition, so I want to be safe. Thank you.

    • Natasha Anderson says:

      Hey! Yes, in fact it works very well as it can reach into the little recesses that may escape other flea treatment products. If there are fleas in these places, it can result in a renewed infestation and much frustration later. Leave it for 4-12 hours, the longer the better the results. Borax is safe for pets but just keep an eye on your cats to make sure as sometimes it can cause irritation. Best bet would be to keep them out the house for the day, just in case :)

      • Yan Liu says:

        Hi Natasha! So glad I found your site. I have been fighting an uphill battle with fleas and have two young children at home (a crawling baby). I tried diatomaceous earth with no luck.

        Do you recommend Borax 20 Mule Team or Fleabusters? Flea Busters states that they are less toxic than Borax, but I was wondering if you have any insight on that and it’s effectiveness. Thank you!!!

        • Natasha Anderson says:

          Hi Yan! Borax 20 Mule Team is great, I suggest that you use that. I havn’t personally used flea busters so I can’t comment on that. Good luck!

  21. leyla says:

    Hi Natasha! I have been battling the buggers for a week now in 90 degree heat/humidity in my no-airconditioning house—Two bombings, one spraying, one dusting powder and then vaccumming, vaccumming, vaccumming. Got a bite with my coffee this morning and want to blow up the whole house and be done with it. HOWEVER, I am going to try your borax method tonight when I get home. I’ve got the borax but HOW do you apply? It comes in a box. Do I just shake on? Should I grab handfuls and broadcast? Thanks for all your help!! Leyla

    • Natasha Anderson says:

      Hey Leyla! While explosives might kill the fleas, The Bug Squad doesn’t recommend it ;) Haha, sorry that you are still having a problem with fleas, they can be a real bugger to get rid of (literally). I usually fill an ice-cream container (or something like it) with borax powder and after punching holes in the lid, I use it like a massive salt shaker to distribute it where necessary. Hope that helps!

  22. Phil Seymour says:

    Perfect articles – Thank You.
    I live in Kentucky and since Spring this year, have been struggling with bites to my ankles, legs and arms. Folks around here have been quick to point the problem at Ticks but after reviewing your article and seeing actual photo’s of other poor sufferers, it would appear that Fleas are the bane of my life (and my body). Will follow very closely your recommendations and a huge Thank You for putting this info out there on the net.

    • Natasha Anderson says:

      Hey Phil! Thanks for your kind words, they are much appreciated :) I will actually be focusing on tick removal in the next couple weeks so you can stay tuned for that for future reference. Have a good one and see you back soon!

  23. Paul says:

    used this method of flea removal and am very pleased with it…thanks for the article

    • Natasha Anderson says:

      Hey Paul! Awesome, I am super happy that you have found it to be effective and that you have taken the time to share your experience. Have a good one and don’t forget to share this new knowledge with your friends and family when you get a chance :)

  24. Rosie says:

    Hello Natasha,

    I have this flea problem for the past three weeks. Initially, I didn’t know it was fleas until i went to the DR. and he told me that it’s not food allergy and it’s indeed flea bites or ant bites. I did my research and found your page :)

    For the past two weeks I used natural remedy, salt/baking soda all over the tile floors and corners and vacuum vacuum. I thought it went away a week and a half ago when my legs healed up. Unfortunately, i had new bites on my back and upper body. I recently bought my dog Sentro Pro flea drops (he always been on Trifexis pill). Frontline is too expensive.. Yes i know…i’m suppose to get the flea drop first sighh…but we bathe him as instructed.

    I also bought Borax a few days ago and been using. Do you recommend repeat process every day until you don’t see any more fleas on the tile? Spread borax, broom around and let it sit for 6+ hours before vacuuming.

    Yesterday i was doing yard work and now i have new flea bites by my shoulders and armpits.. My legs were healing and now my upper body has flea bites sigh..Is it safe to spread borax around plants? I saw the flea on my arm when i was out there and i tried to killed it, but it jump off and the next day a red bump emerge.

    Thank you for your help! Any recommendations would be greatly appreciated. Sorry for the long comment.

      Hey Rosie! No apologies needed, I love it when my readers leave a long, detailed comment as it helps me understand their situation properly so I can assist them. :) Yes, I recommend daily usage and your method of applications is perfect. Borax can be used around your plants but keep in mind that moisture will prevent it from being effective for pest control. As for those flea bites, check out my dedicated article on that subject as there are a number of natural ways to reduce their itchiness and inflammation. Good luck!

  25. Rosa Shamosa :) says:

    Hi. I tried boric acid last night and left on for about 5-6 hours and still they are biting.We’d only cat sit for daughter for about 3-4 days and I cant believe we have this problem now.I bought the Mule Team Borax today and am going to try that tonight.
    I used a broom to smooth into the carpet also.Can it also be spread in our yard to help kill any thats in yard? If so, how to do that?
    Wont it hurt the grass?

    • Natasha Anderson says:

      Hey Rosa! Awesome, let me know how that treatment goes :) Use the broom to actually rub it into the fibers of your carpet and don’t use too much. As for your outside area, you can use borax safely for a single application on flora (in this case your lawn) but after that, there is a possibility that it will start damaging it. You can also use lime (bit more expensive) and this may be your solution as it can be reapplied multiple times without damage (unless the package says otherwise of course).

  26. Rosa Shamosa :) says:

    ….also, I have some DE and accidentaly left the lid off for several days in my carport.Is it still any good?
    I thought moisture might be bad for it.It is a damp area somewhat where I live but the DE didnt seem clumped or anything.
    Thanks again…

    • Natasha Anderson says:

      Hey Rosa! Is it isnt clumped it should be fine. However, I still recommend that you go and purchase some more if its convenient because the last thing you want is to go through the effort of using it, only to find that its not working as expected.

  27. Steve says:

    Natasha, I am SO glad you took the time to explain this to your readers. I’m aghast at all the misinformation and scare tactics being presented as science across the web. Having lived in Florida while rescuing stray cats, I can attest to the effectiveness and unbelievable staying power of the Borax treatment. I was absolutely overrun with fleas until a Vet reccomended it. $20 covered 1500/sq ft. I put it down for 24 hrs, then vaccumed. Repeated a week later to catch the next egg hatch, then 2-3 weeks after that.
    I never, repeat, NEVER saw another flea. Its the easiest, most effective, and cheapest way to knock the snot out of an infestation.
    My cats never got sick either.
    I’d actually reccomend it to ANYONE getting a new dog or cat. Do it preemptivelyh and yhou’ll never be sorry.

    • Natasha Anderson says:

      Hey Steve! Its a pleasure, I am glad that people are finding this article useful. Thanks for sharing your personal experience, there are a large number of readers that see this guide on a daily basis and I am happy that they will be able to see how you found it in the past :) Cheers!

  28. k cole says:

    Hi, I just tried the Borax in my home and it didn’t work as I expected. I left it down for 2days. It probaly did kill some fleas but when I vacuumed with my bagless, I could see them jumping around in there. Maybe the Borax drew them out for me to vacuum them up. I was excited to see how many was in that one room. I’ll redo the same room for a few days to see how many more I can catch. I like to put some purple pinesol in a cup and catch the fleas I see crawling on me or my pet. put them in the cup and it kills them. I tried pouring it on my floor and leaving it but it messes up hardwood.

    • Natasha Anderson says:

      Hey Cole! Did you use 40 mule borax? I know its not a necessity but I know that their brand is good quality and I have personally have success using it. My recommendation is “dusting” your floor with the borax and then rubbing it in with a broom so that it really gets into the fibers, cracks, etc. Leave for about 24 hours and then vacuum. After a few repeats, you will see good results. Alternatively, try using DE, you can find a detailed guide under the flea category on this blog. Hope this helps ya!

  29. Cliff says:

    Hi Natasha, I live in the country and have four 10 month old kittens. I keep them in a horse stall at night, to protect them from predators, that’s screened in with a dirt floor and some straw. We have a BIG flea problem in this stall and would like to know how you would treat/rid the stall, and kittens, of fleas safely.

    • Natasha Anderson says:

      Hey Cliff! My recommendation is to use borax (just follow the steps in this guide) or DE (I have a dedicated article on this subject). Both are completely safe (and very cheap) and will not put your kittens in any danger. Plus, since its indoors and will be nice and dry, it will be perfect for these compounds. Good luck!

  30. DD says:

    Hi Natasha,

    I’ve been dealing with fleas in my home and on my cats for a few weeks now. I treated my cats about a week ago with a topical treatment and used the hot shot brand fogger on my house yesterday. The issue is I have a 2 month old baby who sleeps in my room and I did not put a fogger in there because I was worried about the strong odor and any chemical residue. The flea issue wasn’t too bad in my room to begin with compared to the rest of the house from what I could physically see. I knew there would be a good chance that there would still be some fleas hanging around in there and I right. I have found only 3 so far but I know it only takes one to get everything going again and I also have no idea what the egg or larvae situation is. I have no carpets just hardwood floors. I had 2 area rugs down but have taken them up and put them in a garbage bag to be washed. From reading your site so i figured I would purchase some DE but there is no food grade quality available. I will be purchasing some online and have got some boric acid for the meantime. My question is, is it ok to put that down on the floor in my room with my baby? The baby isn’t on the floor at any point ever and I would be sure to wear something on my feet to reduce any skin contact or track it into my bed. I’m not sure if that would make a difference.

    Thank You

    • Natasha Anderson says:

      Hey DD! Glad you decided to avoid that room, that could have caused complications as there is definitely a chemical residue after application. Yes, its absolutely safe, just don’t put a massive amount down (imagine just “dusting” the floor with it). Use a broom to push it into any cracks, crevasses, etc. and vacuum it up a couple hours later. Its really as easy as that, its not toxic and while you can wear shoes, you dont have to. Good luck! :)

    • Pat Brasic says:

      Where do l get diatomaceous and what does it cost

      • Natasha Anderson says:

        Hey Pat! You can purchase it from amazon (and other places, this is just one of them) and it should cost under $20 for a decent size bag. Hope that helps :)

  31. Dieter Mehling says:

    Natasha, used borax in the two carpeted rooms where we have had a bad problem. Could not get it everywhere because there is to much stuff in there. Will that reduce the effectiveness of the treatment? Those rooms were the cats rooms which we do not use much. I could leave the borax there for several days. Would that help the overall effectiveness? I have seen a few in other parts of the house should I treat the whole house? I am really concerned because we are going on vacation and I really do not want to return to a bad infestation. When we are on vacation should I close the door to the different rooms to isolate them from one another in the event there are some eggs upstairs that hatch?

    • Natasha Anderson says:

      Hey Dieter! Yes it will, however it wont completely compromise the treatment so give it a shot and let me know how it goes. Yes, leaving it should make a positive difference. In addition to that, I recommend leaving a couple flea traps (check out my article on this) in there to reduce the flea population. Lastly, before you go on holiday, its might be worth your while to use a flea bomb, if you have any questions on that, drop me a message and I will assist you personally :)

  32. Lisa says:

    Your article has been so helpful, thanks so much for sharing!
    One question tho, can any if this be used in the yard? If not what is the best treatment for the fleas in the yard?

    • Natasha Anderson says:

      Hey Lisa! Its a pleasure, glad you enjoyed it :) Borax can be used in your yard but if there is any moisture, it will reduce its effectiveness. I recommend cutting back excess foliage (long grass, etc.) and using an outdoor flea spray to target the sweet spots in your yard. Let me know if you need some help with this, have a good one!

  33. Joey says:

    Thank you for the article Natasha. You’re time is greatly appreciated. I’ve used 5 different flea poisons in the last month, and have had NO luck getting rid of the fleas. I have a pitbull that i bathe regularly and medicate with a flea pill from the vets office. I have fleas everywhere but the dog. I put 20 mule team borax down on all of my carpets last night but haven’t seen any results yet. Should I vacuum it up and put more down, or should I just leave it down until I stop seeing fleas? I’ve already spent a lot on this flea problem so I don’t wanna waste money on more borax if there’s no point. I’d appreciate any input. These fleas are driving me crazy!

    • Natasha Anderson says:

      Hey Joey! Its a pleasure, I am glad you have found the article beneficial :) I recommend that you actually rub it into your carpets (I use an old outdoor broom) and leave it there for about 10 hours (might as well leave it for a day). After completing this step, vacuum it up. You may need to repeat a couple times, just make sure that you cover all your bases when it comes to the application of the powder. Let me know how it goes!

  34. Amanda says:

    Hey there! I’m a fairly new parent of an 8 month old puppy. I’ve had him for 6 months and I guess he’s a bit spoiled since he’s taken a liking to sleeping in my bed. Well about a week ago I ended up with random bites on my legs which turned out to be from fleas! I don’t have any carpets, just hardwood floors and linoleum. There’s a carpeted staircase to my second floor apartment. Since the fleas are probably on my bed and leather couch where the puppy hangs out, is it safe to use borax there? Sorry for the long explanation, bugs just make me nervous.

    • Natasha Anderson says:

      Hey Amanda! Cute, I have recently purchased a puppy as well and I must say, I sometimes let him curl up with me in the bed so I know what you mean :) Yes, borax is safe to use around dogs but I still recommend taking your puppy out the room when applying the powder. Also take a moment to check out my DE article, it works much like borax but is even safer for home use (plus its cheap). Good luck!

  35. Perri says:

    I’m kind of torn here…. I bought the Borax but I haven’t used it do to some concerns I have after reading this…. I have a 5 month old kitten and I’m not really sure about using this… Also what about the dangers to dogs? I guess I’m asking is this worth a try with such a young kitty? Don’t want to endanger my little one!!!

    • Natasha Anderson says:

      Hey Perri! I recommend that you don’t use borax around cats (fine for dogs) as it can be rather toxic to them. A great alternative that I recommend for your home is food grade diatomaceous earth, its really cheap and will be safe to use around your cat. If you have any other questions, let me know! :)

  36. Dan says:

    Any ideas about how to apply this in a car to get rid of a few fleas (we just started noticing them out of no where, doesn’t seem to be infested yet).
    We have a 2 and a half year old son that would be in the vehicle but figure we would not use this vehicle for at least a week and vacuum it out multiple times after applying the borax.


    • Natasha Anderson says:

      Hey Dan! I recommend that you dust the seats and the carpets with borax and rub it in bit. Leave it for a day or two, vacuum it up and then repeat a couple times. You will see fairly quick results, good luck!

      • Dan says:

        I just applied the borax to my car but I couldn’t really brush it into the upholstery because it’s not like deep carpeting. I sprinkled the seats and carpet with it. We’ll wait a few days before vacuuming it out.

        Thanks a lot for your invaluable advice!

      • Dan says:

        Okay, it’s almost been 2 weeks, but I didn’t want to jinx anything. Since applying the Borax into the car upholstery and vacuuming it out, I have not seen a single flea, not even a week later when potential eggs would’ve hatched.

        Thank you SO MUCH for the advice from this article!!

        • Natasha Anderson says:

          Its a pleasure Dan, I am super glad that I have had the opportunity to assist you :)

  37. Brooke says:

    Thank you for this information… It really helps. We have two cats and they both have fleas and are ripping their fur out. We went out and bought 20 Mule Team Borax and are going to use it tomorrow. So thank you for the information… We appreciate it!!

    • Natasha Anderson says:

      Hey Brooke! Thanks for your kind words, I am happy that I could help you out. Good luck and let me know if you have any further questions!

  38. Megan says:

    Thank you for your great advice…I’ve found your site very helpful. I have an indoor cat who has fleas. We have a 2 year old and an 8 month old who are both always playing on the carpet. I’ve treated our cat with frontline, but am hesitant to use a flea spray or borax on the floor. Instead I sweep constantly and have tried putting down baking soda and salt overnight. It’s been a week and every time our cat comes into the living room, she still starts scratching and rolling immediately, even though we hardly ever see fleas. I am thinking they must still be biting her. Do you have any safe suggestions for us with our children? Thank you so much :)

    • Natasha Anderson says:

      Hey Megan! Its a pleasure, glad you have found the information you have been searching for :) I recommend giving borax a try, any specific reason why you are avoiding it? Also, please make sure that your cat actually has fleas (check out my flea comb and flea bite article, it will give you some more tips to review). Its possible that your cat may just have itchy skin that is unrelated to flea activity.

  39. Miki says:

    Hi I’m trying borax for the first time today is it okay to leave down longer than 6 hours?

    • Natasha Anderson says:

      Hey Miki! Yes, that is perfectly fine. I will update the main article tomorrow to clarify this point. Thanks for your comment!

    • Gita says:

      Many articles I have read say to leave the boric acid powder down for 4-5 days then vacuum or leave it even longer. I see no great purpose in vacuuming so soon after putting it down unless you are trying to get eggs to hatch.

      • Natasha Anderson says:

        Hey Gita! I completely agree with you, the longer the better. However, the time frame that I list in my comments is purely a guideline, a minimum in fact, that I recommend to enjoy decent results. Also, while its preferable to leave it for long periods of time, due to living conditions it might not be possible. Thanks for your comment :)

  40. Christy says:

    I moved into a home a month ago and shampooed the carpets right away. I saw no fleas until about a week later when they were literally everywhere! I vacuumed, sprayed, used DE that was down for 4 days, sprayed again, used table salt, have a flea trap that I move around every day, used flea carpet powder, and just sprayed again yesterday (I vacuum everyday when I get home from work, the entire house which takes about 2 hours). I’ve done the furniture and every baseboard, crack, etc. each time with all of these methods and I have bought the expensive sprays that are supposed to kill eggs and larvae as well as adults. Three weeks later and I’m still catching about 3 fleas a day in my trap when it is left in one certain spot in my living room. The rest of the house is flea free and we haven’t actually seen any (just in the traps). I am putting down the borax in that areas today and will leave it for a few days. My questions is, when do I know that this problem is finally over? My thinking is that if the trap catches one flea, I need to keep the battle going. Is this accurate? It’s been three weeks and I’m so tired! I’m not even finished unpacking yet because all I do with my spare time is battle fleas. . . . .

    • Natasha Anderson says:

      Hey Christy! Congrats on following through with all those steps, sounds like you are really putting in the effort to get rid of these pests :) Personally, the problem is over when fleas are gone hehe. If you find that your traps are free of fleas for a couple days then you have pretty much won the battle. Let me know how the borax treatment goes, would love to hear your experience with it. Cheers!

  41. Rosa Shamosa :) says:

    ive tried everything.i have been at it for two months. i am going crazy…i used precor 2000 last weekend and it helped some.but i feel them jump on me still.i vacuum all the time and think they lay eggs on me ,bed.i vacuum and wash everything. i dont know what else to do.does ‘Flea Busters’ work? ….also, i dont see the fleas anymore but just feel them jump on me in certain areas of the house…i feel so defiled!

    • Natasha Anderson says:

      Hey Rosa, thanks for another comment on my blog :) Fleas will not lay eggs on you so you don’t need to worry about that. I havn’t personally used Flea Busters but a couple of my readers have told me that it works well. Give it a try and let me know. Good luck!

  42. Toni says:

    Hi Natasha:
    You article is very thorough. Thank you so much. I was confused when reading other sites about Borax…yours is the most thorough. However, I do have a couple of questions. I have 4 cats and I believe I need to treat all the rooms in my house as well as all the furniture and area rug with the 20 mule Borax to get ride of the fleas. The cats have been treated today with Advantage II. Where do I put the cats while the Borax is down? I can not take them out of the house, as one of them is 22 years old and one is feral. Will the Borax harm them? Or harm us? Do I put it down on the sofa’s, hardwood floors, etc? I am astonished because although I’ve seen a ton of flea dirt, I have not seen one flea. Also, when the larvae hatches, will the fleas jump onto our cats and die because of the Advantage II? Is it just best to get an exterminator out to spray? The problem with that is that Stanley came out to inspect our problem and said we had no pests, so they just did a general spray and now another exterminating company is saying they can’t come out for at least a week because something was already sprayed. One further question is…will getting a steam cleaning company to come in and steam clean all the sofas, chairs, carpets, etc going to help get rid of them? Does washing bedding, etc without Borax laundry detergent kill them? Thank you!

    • Natasha Anderson says:

      Hey Toni, sorry for my late response. Glad you have found my content useful, really helps keep me motivated :) I usually keep my cat in the garage during the treatment. Even if you apply it twice, vacuuming up each time, they will only be away from the house for about 2 days. At the same time though, borax shouldn’t affect them too much unless they are very small (I just rather be safe to be honest). If baby fleas land on your cats while it has the spot on, yes it should die after a couple hours. Since you are looking for cat specific treatments, check out my guide on getting rid of fleas on cats, it will answer these and a couple other questions you may have. Steam cleaning is definitely a good option, kills all sorts of pests but remember that you will still need to treat your cats individually. Washing without borax will kill them. Hopefully I answered all your questions, have a good one!

  43. Jack Hofmann says:

    Hi Natasha,

    Thanks so much for this extremely important information on killing fleas without using the big name super toxic stuff. I have followed your directions and have had extremely good success with killing fleas in my apartment. I have somewhat of a unique situation as I have marble tile floors and no pets. The fleas were and are in my bed. Yuck! They are dying off rapidly though. They came to my place in my suitcase after a trip to visit family who do have animals.

    I have an important question relating to killing fleas in my curtains. I live in Taiwan in a completely furnished apartment and if I take my curtains down to wash them, the staff will think I’m nuts. And if I tell them I’ve brought fleas into the building they will be REAL unhappy with me. My question is as follows: If I make a borax spray and spray the curtains, will it be effective? I am not concerned with discoloration of the curtains, I will gladly pay for new curtains out of my security deposit if I can get some sanity now. Also, the borax we have here hasn’t caused discoloration on my grey Ikea mattress or on my sheets.

    I look forward to hearing back from you.


    • Natasha Anderson says:

      Hi Jack! Its a pleasure, thank you for the compliment and I am happy to hear you have had some success. For your curtains, I highly recommend steam cleaning, that will sort things out nice and quickly. Just make sure that the material will be fine under heat though. Good luck!

  44. hillary says:

    been battling fleas for weeks now. gave my cat a flea bath and advantage, i think he’s ok now but in our home is not. i’ve done a routine of washing everything, vacuuming (trashing bad after), and multiple sprays around the house, but i’m still getting bites. we have all hardwood floors and a bunch of area rugs. i’ve been avoiding the borax because i thought you needed to keep it in the carpet for a few days and i have a 4yr old and 6yr old that i am nervous about. is it effective if i vacuum after only a few hours or does it need to be left on for days? is it ok for the kids to be playing on the carpets after a few hours? thanks!

    • Natasha Anderson says:

      Hey Hillary! Since you have already treated (and sorted out) your cat’s fleas, borax will still be effective in your home if you can leave it down for about 16 hours. There is no exact number that works every time but I am confident that it will be down long enough to kill the fleas before you vacuum it up. Borax is natural but rather keep them away from the general area (considering their size). Hope that helps, keep me updated :)

  45. hollylicious says:

    I used this and it worked amazingly well. I also use essential oils as a natural flea remedy and bug spray. I know some essential oils are toxic to cats but i do know lavander and clove are safe and work really well. They also leave the animals smelling nice too.

    • Natasha Anderson says:

      Hey Holly! Thanks for your kind words, I am very glad that you have found something that works. Thanks for sharing your experiences ;)

  46. Heather says:

    Hi Natasha,
    I read your great article about fleas, and I was just wondering does borax powder have the same effect on carpet beetle larvae. I have put the cats into boarding for a few days so I can borax my home. Please reply asap. as I only have a couple of days to do this. I am sooo stressed out. Horrible little creatures. Their needly hairs stick into me and it really hurts. I will be waiting on pins and needles for your reply.

    • Natasha Anderson says:

      Hey Heather! Borax should kill carpet beetles larvae as well. However, the larvae will actually need to come into contact with the borax so make sure you spread it around well. Sorry this is a little late, been having internet issues but I think everything is sorted out now :)

      • Heather says:

        Hi Natashia, Just wanted to know how long does Borax take to kill carpet beetles and their larvae? How long does diatomaceous earth take to kill them? And if used together, how long will it take to kill them. Last but not least, does the Borax or diatomaceous earth stick to them after they have crawled through it? As I told you earlier, I have 2 cats, I have brought them home last week. But after a week, these damn bugs seem to be bothering them also, any suggestions on how to rid the cats of this? Sincerely Heather

        • Natasha Anderson says:

          Hey Heather! After these pests come into contact with either borax or DE (they both function in pretty much the same way), they will die after a couple hours. It doesn’t really “stick” to them but rather cuts and dries out their exoskeleton, causing their eventual death. Borax will not kill the fleas on your cat. I suggest that you take a look at my best flea treatment for cats article as it will give you some more insight into the process. Good luck :)

  47. Christina Boase says:

    Hello and many thanks for your helpful website.

    We have a cat flea infestation in our house and I am planning to use the DE method (timing it with her next Frontline application) But could you help me further with a couple of questions:

    We have 2 guinea pigs who live in a little box of hay in a corner of the room and basically roam around wherever they want. Could they be hosting the fleas (as well as my cat) and would the DE be harmful to them?

    And my 2 chickens tend to wander in before dark for a little sit in front of the fire before going off to their roost.
    Could they be hosting the fleas too? I know it sounds a bit mad (specially the chickens) but they do seem to enjoy it so! Would be very grateful to know if this could be contributing to the problem or whether the fleas are species-specific?

    Many Thanks from Christina

    • Natasha Anderson says:

      Hey Christina! Its very possible, fleas can even get into your home when you have rats around. I wouldnt use DE too close to those pets as they are very close to the ground. It won’t kill them but it might make them breath a little funny. Chickens can also carry fleas but in both these cases, you don’t need to jump to conclusions. Take a close look at both of these animals and check if they have fleas. If you can visibly see them, let me know and we can see what options are available :)

  48. Michelle A. says:

    Hi Natasha,
    I had fleas in my apartment . I fogged the apartment and the building had an exterminator come and spray for fleas.
    Moved to a new apartment and transferred fleas to new apartment and to my car. Had the apartment and car sprayed by exterminator. Now I have bedbugs in my mattress. Had exterminator spray for that. I was bug free for 5 weeks. Now I have a black crawling insect in my car which I tracked into my apartment. I have been dealing with this since July it is now October. I am so frustrated. HELP!

    • Natasha Anderson says:

      Hey Michelle! Have you tried using borax in your apartment, car and any other place where you are finding insects? Borax does a great job at killing all sorts of insects, even bed bugs so I recommend you give it a try. Let me know how it goes!

      • Michelle A. says:


        I will use Borax soon. What solution can I use to clean my shoes to keep from tracking insects from my car into the apartment? If I need to apply Borax to my mattress for bedbugs how do I apply to the mattress and box spring? Also, do I need to apply the Borax to the head board and foot board of my bed?

        Thanks, Michelle

        • Natasha Anderson says:

          Hey Michelle! Personally I recommend that you just give your shoes a quick wipe down each time, its really as simple as that. I suggest you place the borax under the sheet (in small amounts), focusing on the outer rim of the mattress and box. You don’t need to apply it to the headboard, just give them a wipe and you will be fine. Good luck!

  49. Daryl Yonich says:

    Natasha, If you steam clean the carpets thoroughly with Borax in the water, would that get rid of the fleas?

    • Natasha Anderson says:

      Hey Daryl! Thanks for taking the time to leave a comment on my guide :) You won’t need to put borax in the steamer, the heat itself will kill all fleas if you use it properly. Take an hour or two (or however long it takes) to really do it properly and you will be flea free in no time ;)

  50. Trish says:

    Was so happy to have found your article. I discovered 20 Mule Team worked wonders in an apartment a couple of years ago that had a major roach problem. Having just found fleas on one of my three indoor cats, I am preparing to give them medicine but was hoping that Borax would work as well with ridding the house of fleas as it did the apartment with the roaches., Your directions sound very sensible. I have carpet in the bedrooms but laminate and throw rugs in the rest of the house and am hoping a dusting and vacuuming with Borax all round will prove effective.(Actually, I use Borax in my laundry routinely and am betting that is why I haven’t suffered any flea bites myself although they must be around!).

    • Natasha Anderson says:

      Hey Trish! Glad that you have found this information useful! Borax is fantastic and I also find it very effective. Thanks for sharing and hope to see you back soon! Cheers!

  51. Adrienne says:

    Hi there. Thanks for the great article. I live in Canada and wonder if you know where I could buy the Borax that works best.

    I have two pets, cat and dog, and the flea problem most likely originated with the dog. Both have been treated with Advantage so I know there isn’t anything more I can do for them but I’m finding fleas in my house and they attach to my socks! I’m freaking out and don’t want to be “that person” who tracks fleas to work or friend’s houses!

    What is the best process to follow when using Borax when you have to do every room? Can you use it on your bed? Does all the furniture have to be moved (move bed to use Borax under the bed, dressers too?) After the carpet is sprinkled with Borax can you walk on it, or sit on the couch, or do you have to leave the room for the 6+ hours before vacuuming? If I sprinkle the Borax on the floors in my bedroom can I still sleep on the bed? If it’s best to do one room at a time and keep pets out, wouldn’t the problem come back when you do the next room because you then have to put the pets in the room you just Boraxed?

    Sorry for all the questions but this is all new to me and I’m dealing with this problem on my own so am looking for a fast and “easy” solution.

      Hey Andrienne! I know that Amazon in Canada sells it so I recommend grabbing it online if you can. I usually put borax or DE in a plastic container and dust it around the room (kind of like a salt shaker). You can use it on your bed but put it under the sheets. It will also be a good idea to wash all your linen and clothes that have come into contact with fleas. Fleas will only die if they come into contact with the Borax so just keep that in mind :) You can stand on it but rather just leave it for the day and then vacuum it up afterwards. As for your last question, its best to treat your dog, your house and anywhere else (that has fleas) at the same time to prevent another re-infestation. Good luck, hope that helps!

    Hi Natasha,

    Thanks for gleaning all of the information about Fleas and putting them in one place (TheBugSquad)! It really is a wealth of information for people like me who have been finding fleas in their homes. I bombed the house Tuesday night and set out a flea trap last night.. found 2 fleas in the water this morning. I set out two additional traps in close proximity to the light source this morning and will keep at it. I also coated my carpet in a borax/salt mix and brushed it in with a stiff broom. I’m usually pretty lax but I’m always paranoid now, continually checking my socks/ankles with an LED flashlight for any unwanted guests. I REALLY hope that the Borax method with around the clock flea traps (with a lamp) will resolve this issue in the next few weeks. I just want to live in my house normally and can’t imagine how humans in other, poorer countries must deal with critters.

    • Natasha Anderson says:

      Hey Tom! Its a pleasure and to be honest, I really enjoy doing it. Sounds like you have taken the necessary steps to get rid of those fleas. The borax will definitely help you in your battle, looking forward to hearing about your progress so keep us updated :)

  53. sue says:

    hi weve had fleas in our home for almost 6 weeks now…… its just my husband and youngest child whos 4 that are getting bitten, weve used almost £50 worth of bob martin flea treatment and its done nothing, the council came on tuesday and sprayed everywhere and today i found 2 in the flea traps under our bed and my boys bunkbeds does that mean it hasnt worked yet again ??? ive just ordered 3 boxes of borax from amazon but im actually thinking if the fumigater didnt work is the borax im running out of ideas HELP !!!! :(

    • Natasha Anderson says:

      Hey Sue! The borax does a really good job at killing fleas. Sometimes, if applied properly, it can yield even better results then some purchased products. Just make sure you follow the instructions on this page and you will get the results you seek. Please feel free to keep me updated with your progress :) Cheers!

  54. Lauryn says:

    Hi Natasha.. Im sooo upset. We have hard wood floors & area rugs. Yesterday I was sitting on the carpet playing with my 9 month old & found a flee. How can this happen..? LOL Im such a neat freak-vacuuming everyday, cleaning, mopping etc. I have an indoor cat who i give flee treatments to monthly anyway BC we have an empty lot of woods by our house-so i figure its better to be safe than sorry (we give him advantage II for cats) i recently rescued a cat from my friends apartment where i have his whole set-up in the garage i gave him hartz treatment monthly & a flee & tick collar, but recently he’s been running inside. I know it only takes 1 flee but im still so upset. Last night i vacuumed 1st then but borax in the container where the dirt goes the vacuum then sprinkled borax powder on the area rugs, put the cat in his room where his litter box is & put his food & water in there. Its been on the rugs for about 11 hours, im going to vacuum it up b4 the baby wakes up. My question to u is do u think that’s good enough..? Or should i do it again tonite..? And i know it’s not safe for the cat to walk on but i want to put some in the corners around the house, do u think i would be able to leave it there for a few days..? Your article was soooo helpful & im sure it sounds like im all over the place. LOL.. I look forward to hearing back from u w/ any additional advice. Thank you so much.
    Love Lauryn :)

    • Natasha Anderson says:

      Hey Lauryn! If you are still giving that new cat a decent spot on treatment and use borax to kill fleas in the house (which it seems you are doing), that’s definitely a step in the right direction and you will see decent results. However, I cannot confidently say its all you will need but you are more than welcome to drop me a message if there are still fleas hopping after a couple days (its fine to leave the borax down for the entire time). Good luck!

  55. Suzie says:

    I have flees in my basement can I just leave the powder there or I need to keep putting it down?

    • Natasha Anderson says:

      Hey Suzie! You can just leave the powder down, there is no urgent need to remove it unless it gets wet or damp.

  56. Shanea says:

    Ok after using the borax how long should I wait before letting my 1 year old roam the floor? Should I vacuum several times before letting him back on the floor?

    • Natasha Anderson says:

      Hey Shanea! After vacuuming the stuff up (properly of course), you can let your child back in almost immediately. If you want to be extra cautious, just give the floor a mop as well (if its tiles, etc.) and you will be fine :)

  57. Arlene Holcombe says:

    Though you have helpful information, it won’t copy from my printer, which means I had to take notes from your page. Also, when I copy your info, I really don’t want to copy all the comments people make. There should be a way at the end of each article to print just the article. There are two problems here. I hope you will address both. Thanks. Arlene H

    • Natasha Anderson says:

      Hey Arlene! I am glad you have found my info useful :) I will definitely look into those two problems, thanks for bringing it to my attention! In the meantime, you can just use your mouse to select the text you want to save and then paste it into a program like Word or even notepad. Hope that helps for now :)

  58. Roberta Conley says:

    We have horses eating the grass closer to house where dogs go, and we have fleas all over the house, our dogs get the flea pill monthly and baths. I’m going to try the borax treatment in house ,as fleas are jumping on me ,even with constant spraying of dogs,.Is Borax safe outside with horses munching grass in the treated area?Plus ,we bring the fleas in on us too. Help !Please remedy !

    • Natasha Anderson says:

      Hey Rob! I recommend that you use DE for the areas suggested. Make sure its the food grade variation (check out my article on using Diatomaceous Earth for fleas) as it is completely safe for animal consumption. You can even use DE inside your house, it wont put your family in any sort of danger.

  59. Ashley says:

    Hi Natasha,
    My husband and I really found your article to be very helpful in our situation. We recently moved into an apartment, and the previous owner had kittens which had fleas. Unfortunately, instead of the previous owners telling us this information we found out the hard way. I am on my second day of having the Borax sitting in our carpets. I am really hoping that we get some good results this way. My other question was, how do you go about treating the Eggs? We tend to have very shallow carpets in our apartment so I’m not really sure what to do from this point forward. Any other information you have would be so greatly appreciate it. Thank you for taking the time and energy to both thoroughly research and produce this article.


    • Natasha Anderson says:

      Hey Ashley! Glad that you have found it helpful :) The eggs can be removed with a decent vacuum cleaner or alternatively, a hot steamer or continueous application of borax (for a good couple weeks) will do the job. I highly recommend the first one though, even if you have to borrow one from a friend. Good luck!

  60. Anna says:

    We have had a flea infestation for several months and we have tried everything – Foggers, cedar chips, pennyroyal, bombing 5 times, spraying, vacuuming, washing everything in parasite killing solution, mopping the kitchen/bathroom/laundry with insecticide, treating the garden and patio, etc, but we still have fleas! I have treated my 2 cats with frontline every month, but it just isn’t working. When we bombed, the second we walked back in, fleas jumped all over us. I can’t stand it any more, we can’t have people over, and if we can’t get rid of them soon I think we may have to call the exterminators. I really don’t want to do that, as it’s expensive ($450!!) and we’ve already been exposed to so many chemicals. Will borax work on them? I only ask because they seem to be immune to everything we try. Please help!!!

    • Natasha Anderson says:

      Hey Anna! Borax works great and I highly recommend that you give it a try before hiring anyone. Just make sure you follow the steps in this article and you should start to see results after a couple applications. Good luck!

  61. Rachel Sheward says:

    Hi natasha I have a litttle 3 old boy and a dog. The problem is now all the fleas are now in the sofa and in my little boys bed as in my bed as well . I have used three diffferent flea spray treatments from the vets and none of them have worked . Can I used the borax treatment on my mattress and my little boys mattress . As now the flea problem is really bad.

    • Natasha Anderson says:

      Hey Rachel! Rather use food grade DE (check my article on this) under his sheet (after hot washing everything of course), under the bed and any other places where you have a flea problem. Combining this with my DIY flea trap, you should be able to get rid of them fairly quickly. Good luck!

  62. Fran says:

    WELL..We have NEVER seen a flea on my 8 dogs and 2 cats…until 2 months ago..WE ARE IN HELL!! To be clear, we see 2-4 fleas when combing pets but am panic-stricken. As an O.R.nurse, I thought the “strategy” to kill fleas would be simpler than working in a sterile O.R. environment..NOT!!! I wonder how others are preventing contamination from flea to pet to carpet?? We vacuumed,, took or threw out everything and used Martin’s adulticide and IGR twice, now. 2 Cats and 8 dogs had their 4th baths just now, but can’t put them in the prepared Borax room until they are dry. One cat had only 2 fleas prior to bath. The lazy heavy cat had many. The dogs have none or 1-2 fleas. We even filled a large white bucket with vinegar and water for the cats’ final rinse. I sit up at night with a magnifying glass, seriously. I put only white sheets on my bed and examine every single black dot. i wonder why no one has taken magnified photos rather than viewing as under a microscope. I learned, I think, that the flea excrement is like a curled “C”..Also, I observe something the size of a flea covered with beige little strings. I don’t know why this is important but for me, I want to know if tiny black dots are flea related or not. Do you believe that the inhalation danger of Borax powder is due to the ingredients or similar to harm caused by inhaling all powders? I vacuumed up one room of Borax after 3 days. Does the Borax continue working after I put the dry cats in there? But cats are waiting to dry in the Living Room. Once, we put them in the Borax room, we plan on Boraxing the Living Room. In a 3 story home. It is not only frustrating..It’s driving me NUTS, And yes, I use Frontline Plus on all 10 animals,. The dogs go outside at the most 10-30 minutes each day.. The cats have never been outside. I was asked if I see Fleas on the counter or do I get bitten on my ankles!! I replied, “NO”..Is this next? Am I ever going to be Flea-Free?.I have tried to develop a non-transfer of flea method but have failed. In two weeks.. 40 baths, 40 regular rinses, and 40 vinegar water rinses have been completed. And so, for 2 days, the cats will stay in the Borax room. I have bowls of H20 with gtts of soap under a lamp in every room. After chemical sprays, only 1-2 fleas after 3 days. I have done everything except salt, baking soda and coconut oil. Any advice would be greatly appreciated. I am so tired. I know my message is scattered but..last one…Is the chemical spray still working in my Living Room from 2 weeks ago. My wet cats are sitting on this carpet awaiting their transfer to the Borax room. If they are picking up fleas after being rinsed in vinegar water..I give up..I LOVE YOUR PAGE..and read it several times to make sure I haven’t forgotten something.Also reading it makes me feel better sometimes…Maybe because I realize that I am not alone. Thank You!!

      Hey Fran! Thanks for your long and detailed comment and kind words :)

  63. Debbie baker says:

    Hi, ive just found this post regarding borax and fleas, im in the UK, and have just ordered 1,kg of borax powder today from ebay after talking to my friend, do I need to every inch of carpet upstairs? Or just around the beds furniture etc? My cats have been treated with frontline and im still seeing fleas on them !

    • Natasha Anderson says:

      I suggest that you apply it where you find fleas. So if that’s in all your carpets, then do all of them. Yes, until your house is flea free, your pets will continue having a problem with them. Good luck!

  64. Kim Lemke says:

    We moved into a flea infested house almost 3 weeks ago. Within 2 days, my dogs were loaded with fleas and I noticed that I was starting to get bites. We did the necessary dog treatment, bathing, combing, Advantix and as it continued, even used Capstar. My larger dog gets severe dermatitis, and this began to flare up as well. Landlady sent over an exterminator immediately. Countless loads of daily laundry, and flea preventative methods (used the DE in one bedroom, but it ruined my vacuum, as my filter clogged up and dust was everywhere, that was a nightmare!), I even took Dawn dishwashing liquid with water and sprayed over every surface of carpet and furniture . We plan on getting some of our carpeting replaced and one carpet man who came over for a quote, suggested the Borax. The exterminator came back a few days ago as more eggs must have hatched as the fleas made there presence on my dogs again, and I had bites everywhere, even after the treatments with Advantix and everything else I am doing for them. Just to be on the safe side, I purchased a couple boxes of Borax (hard to find, btw, I got mine at ACE Hardware). Today I am starting the application and just wanted to thank you personally for your wonderful post. It has been a battle that I intend to win, and it is comforting to know that there are testimonies and that I am not fighting a losing battle!!! Thank you Natasha!!

    • Natasha Anderson says:

      Hi Kim, its a pleasure! Sorry this is a little late :)

  65. Susan G. says:

    I know you say not to get it wet, but I’ve gotten rid of fleas by dissolving about a cup of borax in the water tank of my home carpet cleaning machine. You need to use very hot water and then make sure to run clean water through the machine when you’re done so that the borax doesn’t recrystallize in the machine, which can cause it to clog. Don’t rinse the carpet, just let the solution dry in it. This method seemed to take care of the eggs as well and no more fleas after one application. This may not work for all carpets, and so anyone trying this should test a small concealed area first. Borax is used as a laundry additive, so I figured if it was okay for clothes it would be okay on carpets.

    • Natasha Anderson says:

      Hey Susan! That’s a great suggestion, thank you so much! I must admit, I never thought of doing that but since you have had success with it, I will do so (hoping I don’t any flea issues anytime soon though hehe). The community really benefits from ideas like this, thanks again for your time!

  66. Jenna says:

    Hey Natasha we’re two months into battling our fleas in our apartment with no pets. Finally got it down to where their not visible and not catching any in ours traps but we still get a new bite everyday I believe from stragglers we are going to try borax acid today orkin has sprayed precor 2000 3 times but I believe they are following us in from the car which isn’t infested just a few from the apartment in there but the going back in forth with them is what is making things more difficult but treating both today with borax I hope it works our fleas are tiny! Thank you so much for all the information!

    • Natasha Anderson says:

      Hey Jenna! It’s a pleasure!

  67. Jeanetta says:

    I have put my dogs to live out of the house, since we are trying to get rid of the fleas. Is it better for the pets to live outside? We don’t want to have another flea infestion, and I don’t like pets in the house, but if they should be inside instead to make the problem better, I would rather that. Thanks!

    • Natasha Anderson says:

      Hi Jeanetta! Yes, that’s a good temporary measure, at least until you can get the flea situation under control. Get them a spot on treatment and let them back in (if you want) after a week.

  68. Nastassia says:

    Hello Natasha,

    I’m happy I came across your site. My husband and I are currently fighting the battle to get rid of fleas we brought into the house from our yard (and possibly the random neighborhood cat that likes to hang out in our front yard sometimes- that we’ve started ignoring now!) We had Terminix come do the house last week, but we’ll be bringing them back for a second treatment as the guy didn’t so such a great job in the basement. :( ((We used a flea fogger down their today, but I still want the pros to come back in a second time)). My husband also just used yard treatment after cutting the grass to help reduce the fleas that are hanging out in our yard. But we were perplexed as to what to do with his car because it seems even after spraying and vacuuming numerous times, they weren’t going away. We’re going to try the Borax approach for the car, because it would suck for us to bring them back into our house after all the drama we’ve been through. The bites don’t impact his skin nearly as bad as me. They turn red, inflamed and basically look like I have some sort of plague. D: I’m all pinked up with calamine lotion right now as I type, lol. But anywho, I just wanted to say thank you for this article as I’ve learned something new about the Borax (and also the DE). We’re going with Borax since we don’t have pets, though.

    • Natasha Anderson says:

      Hey Nastassia, its a pleasure :)

  69. Jons Blakk says:

    Thank you for this. I’m about to try this, I will let you know how it went…

    Hi my name is Kathy twice I have used Pet Armor on my dog for flea control apparently it did not work I have give him 3 baths a week after applying Pet Amror which is stupid ,also the fleas have gotten in my carpet which I have treated throughly ,and now I’m just kinda wandering if I might have them in my hair????And what I can use to treat my hair ?? I’ve even tried hair dye .please respond QUICKLY……………….

    • Natasha Anderson says:

      Hey Kathy! If you do, a simple shower will remove them, nothing to worry about :)

  71. Wendy says:

    Hi Natasha,

    I’ve starered seeing fleas in my house despite the fact that I have no pets. I have been reading lots of articles and decided to try a flea spray with growth regulator. I cleaned and vacuumed everything in my room and then sprayed the entire carpet. I came your article after having done that and I’m wondering if I can sprinkle borax on top of the flea spray or would doing that be counterproductive. I am not sure if the borax will absorb the flea spray on the carpet fibers.

    • Natasha Anderson says:

      Hey Wendy! It won’t be counter productive but rather wait for the spray to do it’s job and then apply the borax.

  72. marsha says:

    How do you get rid of fleas and their eggs on adult cats? Front line plus doesn’t work.

    • Natasha Anderson says:

      Hi Marsha! Give Advantage a try, sometimes it works better for some people :)

  73. Melanie Huffman says:

    I have an unoccupied rental house two hours away from where we live. It was vacated by renters but they left behind a giant flea infestation that we have been trying to squelch for five weeks now. We hired an exterminator twice just to remove all of the carpet and tack strip. We bug/flea bombed at least three times in all of the rooms. We sprayed the entire house with Dr. Martins IGR Spray and we continue to have fleas . We sprayed the lawn with Bayer Advanced yard spray, sprinkled salt and vacuumed daily for three days. The fleas are relentless. The floors that are left are bare and wooden, concrete or linoleum. Someone recently suggested Borax. What is your recommendation for the borax treatment? No one lives there but we have to drive two hours each time we make a trip. However we do have a man we’ve hired to help us with some of the treatments and vacuuming. Thank you for helping us!

    • Natasha Anderson says:

      Hi Melanie! I suggest finding another exterminator, he should be able to get rid of the fleas and its unacceptable that they are back. That’s the best option for you I think.

      • AJ says:

        Hi Natasha! I have been reading all of your articles regarding flea treatment and I would greatly appreciate your opinion on our specific situation; although it sounds similar to Melanie’s. We bought a house and are not living in it yet but have discovered the new house has a have a flea infestation. We had the exterminator come out last Wednesday and spray the entire house, main floor which is all hardwoods and tile and the basement. When we go and check on the house we have noticed the fleas seem to be smaller so we are hoping this might mean that these are the new fleas that hatched? Our exterminator said that we would still notice some but the residual would kill them. He said he used a growth regulator so I guess these could be new ones but I would have thought they would have died from the chemical. When do you think I should use the borax treatment? I was trying to wait as not to interfere with the chemical from the exterminator but we have to move into the house in a week and I really wanted all the fleas gone. Do you think we are wasting money with the exterminator? Any advice would be greatly appreciated?

        • Natasha Anderson says:

          Hi AJ! I don’t think you are wasting your money to be honest. I also think you should wait a couple more days (for the chemical to take effect) before applying the borax. Hope that helps.

  74. Leslie Loven says:

    I have been told to sprinkle Mule Team on the earth floor of my dogs outdoor kennel before I put the straw and cedar shavings down.
    If this is okay, then I just “sprinkle” it around?
    But not overuse it?
    Thanks Natasha

    • Natasha Anderson says:

      Hi Leslie! That will be fine, you can put a little more than a “sprinkle” though.

  75. Martha says:

    We are plagued with ants every where can I use borax to treat my yard without harming my dogs and cats

    • Natasha Anderson says:

      Hi Martha! Yes, presuming that the weather is dry, borax can definitely help you treat the yard safely.

  76. Linda T says:

    My daughter has discovered fleas on her second story balcony. She has lived there for 2 years with no pets. I don’t understand how she can have fleas on a plank balcony. She is not sure how to treat the fleas because any treatment will filter down to the downstairs neighbors porch. Help!

    • Natasha Anderson says:

      Hi Linda! If they are confined to the balcony, I recommend just using dish soap and warm water to wash it down. The fleas might have come from a bird or something.

  77. Tom says:

    I’ve been getting bad flea bites in my room, and I caught and killed two of them, so today I dusted my whole floor with 20 mule borax. The only thing is I didnt apply it under my bed as it would be heavy to move. Do you recommend moving the bed to apply borax there or would having it on a good portion of my rooms floor suffice. Also people in the other rooms have not been getting bit, but would you recommend using Borax throughout the house if the fleas have been only in my room? Thanks!

    • Natasha Anderson says:

      Hi Tom! Yes, I recommend it, sorry lol. If you feel that fleas could have reached those areas, yes do that as well. You could also use my DIY flea trap guide to check if there are fleas in those rooms.

  78. Susan C says:

    Hi Natasha, I bought a 4lb bag of Safer brand DM and am terrified to use it on my carpets to kill fleas in fear of hurting my cats. Have you heard of this product?
    It contains 77% DM with 22% other ingredients. I saw one Safer DM review that a person had to put down their cat due to contact with the DM powder. I’m considering Mule Team Borax as a safer alternative, but want to make sure I get the best flea eradication without harming my cats.
    My cats have all received topical flea treatment, and I can keep them out of the treated rooms for at least 6 hours and while I’m vacuuming up the DM or Borax, then rotate them into the just vacuumed treated rooms while I hit the rest of the house with DM or Borax. Please advise the best treatment DM or Borax. Thanks!

    • Natasha Anderson says:

      Hi Susan! If it doesn’t say “food grade” on the packaging, I advise against it. Mule Team Borax is also a great option, both work. You could do that but you kinda want to leave the DE or borax down for a day or two before vacuuming it up.

  79. Pam says:

    Hello Natasha, I think I have fleas and ticks problem at home. I don’t have pets but I do smelt strong dog smelt and urine when I cleaning up my laminated floor in certain areas. I believe previous renter must have a dog and I got bites and crawling since this April.

    I have itchy ears all yhe time. I believe now fleas larvae live on my scalp but Dr could see them. Any recommendations on how to get rid of flea eggs and larvae on my scalp and feet if I couldnt get dr prescription?

    • Natasha Anderson says:

      Hi Pam! It’s unlikely that you have fleas/eggs/larvae on your scalp. I think you are having a skin allergy, ask your doctor for something to treat the itchiness.

  80. Kristen Avery says:

    Hi Natasha! I loved your article. Unfortunately I read it after going a bit borax crazy all over the house. We have confined the cat to a room with hardwod floors until her heavy duty flea collar kicks in. I havue two qestions. I know that you said the borax can cause breathing problems in cats and could be fatal. Should I be worried about this if I keep her in a seperate, borax free room until I vaccum everything up? Also we used one brand of topical flea treatment on her that did not work at all thenbught a higher quality flea collar that does the same thing as a topical treatment and put in on a couple days after her last dose of the previous treatment. She has had several baths in between. Should I be worried we might have over dosed her? Oh and what gets rid of flea eggs? Sorry that was an extra question. Again, your article was very well written and informative. Hope to hear from you soon !! Thank you

    • Natasha Anderson says:

      Hi Kristen! Yes you can do that, good idea. I highly recommend that you stay away from flea collars and yes, keep her off any chemicals for awhile, you don’t want to over do it. Have you tried something like Frontline? I suggest you check my article on flea eggs, all the info is there. Thanks for your comment :)

  81. Penelope Anne says:

    It is a very dry Summer here at present, and I have a flea issue outside, and they keep reinfesting my pug. Will Borax work outside?

      Hi Penelope! Yes it would but you will need alot of it lol. I rather recommend that you use a spot on for your pug.

  82. Sheri B says:

    Hi! We are buying a repo house next week. The house obviously is vacant as it’s a repo. There is carpet and linolium in the house right now. We are replacing everything. One of the workers came in and said that he felt little bites at his ankles and thinks we have fleas. How do we know for sure what that is or should we assume it is fleas? If we are replacing the carpet and other flooring in the whole house, how should we proceed to get rid of the fleas? Should we do the borax and then rip out the carpet and replace? When you vacuum, isn’t there possible live ones that can go inside the vacuum and then come to my current house? Thank you for your help!

    • Natasha Anderson says:

      Hi Sheri! I think you should go and look yourself, it might be fleas but you would have to confirm it. Just take the carpets out, discard of them properly and then mop the floors with warm water and soap, that will kill fleas instantly.

  83. Andrea says:

    Good morning Natasha! Thank you so much for this article and all of your research. I sometimes believe that you can drive yourself insane when you Google about a certain thing. I have had my dog for 10 years and this is the first year (that I believe) that I found a few fleas on him. I believe he may have brought them home from our groomer. I also have to share that I did not use Frontline for 2/3 months.. (I will never forget that again). I have been going out of my mind with just the thought of finding a few on him. I have cleaned and dusted my home on a daily basis with the hopes that they are not on my furniture, carpet or any floors that I have. I brought him to the vet and they confirmed that he does not have flea dirt on him therefore I hope he did not have many on him. My concern is now my house. I haven’t seen any fleas and do not have bites, however how could you know if you have flee eggs? I am assuming the only way to know is when they hatch which haunts me. I vacuum every day and throw away the bag. Can you recommend any thing else before I rip up my carpets. Thank you!

    • Natasha Anderson says:

      Hi Andrea! Its a pleasure! I suggest you make one of my DIY flea traps (article on this blog), it will instantly tell you whether you home has fleas or not. Let me know how it goes.

  84. Tara says:

    I recently bought a house and after moving in discovered the basement had fleas. We sprinkled borax all over down there and then left it. We haven’t put anything down there yet. It has been 4 weeks since we sprinkled borax all over down there. Unfortunately I had friends over this weekend and their kids opened and went down into the basement – along with the kid went one of my cats. I didn’t realize the cat had gone down there until several hours later he was crying at the door. I let him in and didn’t think much of it because we sprinkled borax everywhere 4 weeks ago.. Well yesterday I discover a couple fleas on the one cat. I needed to do another dose of Frontline on them anyways so I did that immediately.. I woke up this morning and have bites all over my feet/ankles. I keep all the bedroom doors shut and the cats never go in so I’m guessing I got bit from sitting on the couch. The living areas are hardwood with some area rugs. I purchased DE last night and waiting for it to arrive but in the mean time am I ok to sprinkle borax on the area rugs? I cant take the cats anywhere so I wont be able to leave the borax on for extended amounts of time. To be honest I was really disappointed that there are still living fleas in my basement.. No one and no animal had been down there in the 4 weeks since we’ve moved in.. They didn’t die and now I am freaking out because we just installed brand new carpet in the 3 bedrooms upstairs. Anything else I can/should be doing? I’m so creeped out I don’t even want to spend anytime in the living room on the furniture.

    • Natasha Anderson says:

      Hi Tara! Yes you can do that. The DE should work well, just take it easy when applying it, it can be quite dusty hehe. If you are still at your wits end, drop me a message and I can organize a few free quotes to remove the fleas professionally.

    Hi, I have a 13 week old kitten that I just got off someone on Monday, last night(Saturday) I noticed fleas on him, I bathed him in flea shampoo right away, and got him left in my laundry room till Monday when I bring him to the vet, how long do it take to get fleas in carpet and for the eggs to be there? Z

    • Natasha Anderson says:

      Hi Dani! You shouldn’t have any issues, just keep an eye on the situation.

    Hi, I’m building a new construction. My friend told me to put Borax powder on the ground inside the framing before hanging/closing drywall to prevent termite.
    Does Borax powder work to prevent termite?


    • Natasha Anderson says:

      Hi Rudy! I presume that it would be for something like that yes, I haven’t personally done this myself.

  87. Chris ricco says:

    Your information is very helpful. I do have a question. These flee treatments you mention are for the carpet. Can I also sprinkle the salt and baking soda mix (or boric acid) on the furniture and mattresses??

    • Natasha Anderson says:

      Hi Chris! Yes, just keep in mind that you will have to clean it up afterwards hehe ;)

  88. Brian Broda says:

    I am using a Rug Doctor that I own to clean my carpets and hopefully get rid of the fleas. I’m adding Borax to hot water and then cleaning the carpets. Hopefully the brush action and Borax solution will penetrate deep into the carpets and also dislodge any fleas and get sucked up while killing any left behind.

    • Natasha Anderson says:

      Hi Brian, sounds like a plan, best of luck!

  89. Cheryl says:

    Natasha, thanks for this information, very helpful. I had my house treated by a professional pest control company almost a week ago and I’m doing the vacuuming process every day (what a pain!). I’m thinking of using borax in a few days because of the severity of the flea problem. Do you think it will decrease the effectiveness of what the pest control company applied?

    • Natasha Anderson says:

      Hi Cheryl, it won’t, go ahead and use it. Thanks for your kind words.

  90. Melinda Miller says:

    Natasha I have put the borax down and I have treated the furniture with fine sea salt, I have 8 inside only cats age 8 to 3 months, I read to leave the borax down for 6 hour’s can I vacuum and shampoo my carpet to clean up. Also my cats do still have fleas but I’m using dawn and a flea comb. Can I shampoo the carpet and I’ve based all the toys and I have washed all the linens. I need to know if I’m doing everything right. Thank you

    • Natasha Anderson says:

      Hi Melinda, yes and it sounds like you are doing things correctly, keep it up!

    I am currently on the tail end of a protracted war (over 4 months) with fleas and bed bugs. A lot of things you buy at the store don’t really work (at the beginning I tried all of them.) Here is what in my experience does: Skim coating the walls (an other hard surfaces) with Borateem diluted in hot water with a clean sponge mop pretty much stops them there. Diatomaceous Earth works, but takes too long. Boric acid works but drives the fleas into a frenzy, so isn’t practical until the flea infestation is considerably reduced (mine was prodigious and spread throughout the whole house, bedding and clothing.) The reduction was done with a commercial application of Procor. They say it will get rid of all of them in one month, but that didn’t work. But, it did really reduce the number of them. Then I used Boric acid powder and it started working very quickly. After 10 days I will vacuum it out and put Diatomaceous Earth to prevent a further infestation. During the battle, I washed my day’s clothing and bedding every day. Also, I ran my pillows through the dryer everyday to control any fleas that got on them. And I took a hot bath with a 1/3 cup of laundry chlorine bleach added to a full tub (suggested by my medical doctor) to kill the fleas on me and in my hair before I went to bed. FYI, I don’t have any pets and I live very cleanly and orderly alone. To infusion evidently came from my neighbors as I walked along the hallways, since I am on the third floor. Heat rises and so evidently do fleas. I got a lot of confusing and misleading info when this first came up, hence the delay in results. But, when I figured things out, progress came pretty quickly. Your suggestions are sound. Good luck to anyone fighting this horrible situation!

      Hi James, thanks for your kind words :)

    Hi love your article!! So I’ve been reading a lot about borax to kill fleas and dust mite if I sprinkle borax on my carpet and leave for 2 days is it safe to walk on and safe for my kids my youngest is 8.

    • Natasha Anderson says:

      Hi Kelly, yes its safe.

  93. Kathy B says:

    HI, I’ve been reading all the questions and answers which are very informative! However, I still have a question of my own. I have mostly hardwood floors with carpeting in only my 3 bedrooms. I understand about putting Borax on my carpets but am still a bit confused about the hardwood floors. I have 4 dogs and 3 cats. If I sprinkle the Borax on my hardwood floors, can my dogs and cats still walk or lay on these floors. It’s hard to confine them to one room, but it could be done. I’m thinking of putting them in a bedroom all day while I’m at work and putting the Borax down on the hardwood floors and vacuuming it up as soon as I get home from work which is about 10 hours later. May I have your advise please? Thank you!!!

    • Natasha Anderson says:

      Hi Kathy! Yes they can, that sounds like a good plan, go for it.

    • Natasha Anderson says:

  95. Avril says:

    Hi Natasha
    Great article – thank you! I have had a flea infestation in my kids bedroom. I have used Borax as suggested on the floors and carpets. All clothing and bedding have been washed at a high temp, dog treated and dog bedding all treated. What about the kids beds? I have sprinkled Boraz on the mattress just to be safe – will this work? Many thanks

    • Natasha Anderson says:

      Hi Avril, sounds legit, I am sure you will have good results :)

  96. Nicole Oliver says:

    Hi! I have had a huge flea problem for about 3 weeks now. My boyfriend and I decided to get a kitten which is about 3 months old now. I have been using sprays and all other types of remedies with no luck at getting rid of them. I recently put advantage II on my pet and have been looking for home remedies. I live in a studio apartment with only wood floors…no carpet what so ever just bedding & mattress. I have been covered in flea bites and was wondering how I should use the Borax to eliminate the fleas on my wooden floors? Also how long should I leave it down to make sure that all of these little vermin are killed? There are also visible cracks on my floor and I am almost positive they are living in there how should I make sure the Borax gets in the cracks?? Please help!

    • Natasha Anderson says:

      Hi Nicole, I have emailed you.

  97. Gerri says:

    We use 20 mule team boron in our waste water holding tanks in the motor home to control odros. It does a great job and we never have unpleasant smells. Now I’m going to try it on bed bugs. Also use it with my laundry soap. And it’s very inexpensaive.

    • Natasha Anderson says:

      Hi Gerri, yeah it is great. Thanks for the comment, good luck!

  98. Eric Williams says:

    I would prefer a liquid solution of boric acid sprayed into the carpet for my particular situation. I have not been able to find any information on what percentage solution to use. I would appreciate any comments on this .

    • Natasha Anderson says:

      Hi Eric, I have only used the powder to be honest, so unfortunately won’t be able to help you. However, if you find something that works, let us know!

  99. Rachel says:

    This method was recommended to me by a friend after I found a flea on my bed last night and noticed my dog was still itching despite being on a supposedly powerful flea treatment. The vet said it was too early for another dose so I treated him with a flea shampoo and powdered Borax over the areas of the house that he hangs out in, including the bed, the couch, and the carpets. I guess the infestation isn’t terrible but as we’re moving in a few weeks I don’t want to take any chances and I really don’t want anything jumping on me in the night. What’s strange is that he was staying with my husband at our new place (I’m still working in this area) the last two weeks, and he says he never saw the dog itching or saw or felt any signs of bugs (and he hates bugs so he would notice). But I didn’t notice any fleas here until I brought the dog home. Sigh. I’m hoping I did everything right. Thanks for the article!

    • Natasha Anderson says:

      Hi Rachel, thanks for leaving a comment. I hope everything is alright now too, let me know if you have any issues.

  100. Rachel says:

    Thank you. I didn’t see any when I treated the house on Wednesday, but tonight I feel like I’ve been seeing alive and dead ones all over. I’m hoping this means the Borax and treatments on the dog are working and they’re all just jumping ship and dying. How long does it usually take?

    • Natasha Anderson says:

      Hi Rachel, yeah sounds like it. Give it about a week or two, good luck!

      • Rachel says:

        Hi Natasha. I need some peace of mind because I found some more this morning, and they seem to be concentrated in one corner of the bedroom so I reapplied the Borax there and also on the carpets, couch, and bed. I’m hoping this is just the second hatching and that they’ll all be gone soon because I’m moving next week and don’t want them hitching a ride. :-/

        • Natasha Anderson says:

          Hi Rachel, I am sure that the reapplication of the borax will kill them. Keep me updated!

  101. Debbie Darlanf says:

    If you have dogs on concrete I have used Borax before is it safe to just spread around. It is fleas that cause tape worms correct? They look like rice

    • Natasha Anderson says:

      Hi Debbie, yeah it is safe. Yes they commonly do but they are not the only cause, thanks for your comment.
