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.

  1. Sim says:

    This article is exactly what I needed. I appreciate the side note that diatomaceous earth can also be used. Thank you for saving my legs from getting all eaten up!

    • Natasha Anderson says:

      Hey Sim! Its an absolute pleasure and thank YOU for taking the time to leave a positive response like this, really motivates me to keep writing new and informative guides :)

  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.

  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.

    • Natasha Anderson says:

      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.

    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.

      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!

    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.

    • Natasha Anderson says:

      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!

  52. Tom says:

    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:

    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!

    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!

    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 :)

    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 :)

    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!

    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!

    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. 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!

  63. 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!
