Where Do Fruit Flies Come From?

Summary: Where do fruit flies come from and how do they find their way into your home? Fruit flies need a good source of food, both for the adults for their their young. If this problem has suddenly appeared, you kill them as quickly as possible as they carry bacteria and pose a few health risks.

The truth is that even those that keep their homes clean can get fruit flies. As a result, wonder where are flies coming from, despite their effects to keep things tidy. Much to the dismay of shop owners and restaurants, they also have a continuous battle to fight against these creatures if they want to keep themselves and their customers free of these bacteria ridden insects. It seems that fruit flies appear overnight and it can be very difficult to get rid of them as they breed very fast. However, a little bit of education and understanding as to the makeup and behavior of fruit flies, you will be able to effectively fight this infestation properly.

Where Do Fruit Flies Come From?

where do fruit flies come from image 11 About 100 years ago, many people believed that fruit flies come from something known as “spontaneous generation” as they always keep to appear from nowhere without any apparent warning or signs of breeding. Since their tools where limited, this ideology was not limited to the common man and was even promoted by the scientists of the day. However, due to increased technology and education, we now know that fruit flies do not magically appear in your home without following the basic steps of reproduction. They have successfully been analyzed for over a century and we now have all the answers that troubled early scientists. One major aspect of their breeding process is that its extremely fast and is one of the reasons why a fruit fly problem can sneak up on you without warning. As a result, its very important to educate yourself about where do fruit flies come from and how you can put an end to their infestation without causing further risks to you and your families health.

What Do Fruit Flies Look Like?

Once you have made up your mind to get rid of  your fruit flies in your home or work place, the next step is to be able to easily identify them. Although its easy to know what they look like when they are sitting on your fruit in your kitchen, that wont help you when they are breeding outside. So what does a fruit fly look like?

What Fruit Flies Look Like

As you can see in this picture, fruit flies are rather small creatures and usually reach a maximum size of about 1/8 of an inch. If you are not too good at imagining that, just remember that about three fruit flies together will be the same size as one regular house fly. This is the quickest way to identify them and differentiate fruit flies from normal flies. Other characteristics include a brownish body (sometimes getting darker in some of the fruit fly species) and a black abdominal region. They also usually have bright red eyes that give away their true identity to those seeking to kill them. There are many types of fruit flies and according to the latest count by biology experts, there are about 175 different species in Northern America and about 3000 different variations globally. The reason why there are so many is because scientists have used the advanced methods to crossbreed species in an effort to understand their biological makeup and as a result, there are now even more species of fruit flies then there was originally in nature.

How Long Do Fruit Flies Live and How Do They Breed?

There are four fruit fly life cycle stages. They are ordered chronologically as follows:

Fruit Fly Eggs

Once the mother has found a suitable nesting place (such as your lovely fruit bowl) and the room temperature is around 21 C, she will lay her eggs (they are similar to a flea eggs appearance but are quite a bit larger) which hatch after about 24 hours. As you can see, due to the speed at which these eggs hatch, you could literally be completely free from fruit flies in your home and then the next day, you could have a serious fruit fly problem. This rapid rate of reproduction is actually a major reason why fruit flies are rather difficult to get rid of and its best to catch the infestation as early as possible.

Fruit Fly Larvae

After the previously mentioned 24 hours, the larvae will hatch and will start feasting on the surrounding food. As we can see in this picture on the left, they look like white worms and are often referred to as maggots. Please note that at this stage, they look exactly like the larvae from regular house flies. However, once they change into fruit flies, there are some key characteristics that differentiate them from normal flies and I will be writing an article on where do gnats come from to elaborate on the details in the next couple weeks.

Fruit Fly Puparium

During this phase in the fruit flies development, the larvae is changing into a fruit fly inside a hardened outer shell. (otherwise known as it’s metamorphosis) Its easy to see when this is about to happen as the hardened outer shell of the larvae begins to change into a much darker color, as shown in the picture. After a short amount of time, you will have a fruit fly buzzing around your house, eating your fruit and sitting on your lovely meals. This needs to be avoided and its important to identify these signs as early as possible.

And finally, we have our fruit fly and all the problems that these pests can cause in your home or office. The scary thing is that within 60 hours of coming out of its shell, the females are able to lay up to 500 eggs. And within another 48 hours, those 500 eggs will become fruit flies. Even if only half of those are female, they each can lay 500 eggs EACH after another 60 hours. And remember, that they will eat almost anything that is rotten, especially your fruit.

I am sure you can see that within a very short time, you can have a huge infestation on your hands. It is especially important to be extra clean around the house (or office) if you are going to be away for a couple days as you could come back to thousands of fruit flies flying around and I am sure that you don’t want that.

Just remember the basics of keeping your house clean, throwing away unused or rotten food (and disposing of your garbage as soon as possible). If you already have a fruit fly problem, I highly recommend that you give my previous articles a read. After that brief explanation of the process of where these flies come from, I am sure that its answered some of your questions about possible fruit fly remedies. Thanks for reading my latest article on the origin of fruit flies and I look forward to your comments or any input you may have. :)

    It is so easy to get rid of these flies, I am surprised no one has mentioned it.  First, take two small dixie cups, stick one in the other tightly for added strength.  Then cut two or three slices of well ripe bananas and drop in the cups.  A couple of small well ripe banana peels will help.  Then, take a piece of saran wrap about six or eight inches square.  Stretch it banjo string tight over the top of the cups and wrap it tightly around the cups ending up twisting it tightly at the bottom.  This is to prevent the flies from escaping after the next step.  Once you have the contents sompletely sealed inside the cups, take a round toothpick and punch a couple of dozen holes in the saran wrap.  Push the toothpick all the way in to the thickest part of the pick to make the largest hole.  Make quite a few of the holes just inside the rim. Flies lighting on the rim find the near holes to the rim easier than those more to the middle.  Flatten the bottom well so it will sit level or take a third cup, turn it upside down, and tape the upper and lower together to make a sturdy stand. Place the trap where the infestaation is the greatest and retire to the bedroom to read your favorite book. In twenty four hours, you will be presently surprised at all the trapped bugs.  They smell the bananas, find their way thru the punched holes but cannot find their way out.  When full, take outside and treat them to a propane torch or other form of torture that you can dream up. I would recommend leaving a small light on near the trap.  The flies seem to become inactive in the dark.  Now, wasn’t that simple?  And cheap.

    PS  You can use a larger paper cup than the dixie cup.  Perhaps a coffee cup the size you get at McDonalds.  Size in this case, doesn’t matter.

      Hey Colombo, thanks for that fantastic guide, I will definitely give that a try the next time I have a fruit fly infestation! I also appreciate you sharing it with the communit

    Ive got a fruit fly infestation, millions of them. Normal fly spray just makes them hyperactive. I read an article about it, and saw the cider apple vinegar, which I didnt have, so got 2 small pots, put a tea spoonful of balsamic vinegar, and a desertspoonful of rose wine, put cling film over, with small holes in.
    Got up this morning, and there must be about 50 in each trap. Works wonders :D

    • Natasha Anderson says:

      Hey Dibbles!

      Fantastic, glad to hear that you have had success and thank you for sharing that with us! 

      Have a good one!

  7. Chef Pam says:

    I’m working in a restaurant and I’m usually the one who’s responsible for the cleanliness of it. I got a fruit fly infestation last month so my boss wanted me to handle the problem or my employment is done…..yeah I hated my boss. Anyway I have managed it! What I did was I made a fruit fly trap out of coca cola plastic bottles :) I hung 5 of them around the restaurant and the fruit flies chose the trap instead of our food. Of course hanging plastic coca cola bottles around the restaurant will be unpleasant to the customer’s eyes so what I did was I decorated and painted the bottle to make it look like a traditional native lantern :)

    • Natasha Anderson says:

      Hey Chef! Hehe that sucks but it seems that you did a good job of it, love your idea of decorating the traps. Just make sure that you clean them regularly and take some steps to keep them away permanently otherwise you will be fighting a continuous battle. Let me know if you need some help with this :)

  8. ArnoldTheGreat says:

    Hi, I love this guide. Can I ask a question? I’m living here in a high-rise building and i’ve been diligently trying to get rid of these flies. What is the best way to get rid of them quickly? I do not mind spending a few bucks. Because I was embarrassed when my colleagues sat on the couch and there were flies hovering all over them :(

    • Natasha Anderson says:

      Hey Arnold! I think you just did ;) Hehe, not to avoid the question but you can find an exact (and easy to follow) removal guide right here on this blog, just visit the fruit flies section at the top of this page – if you have any further questions, please feel free to message me and I will help you personally :)

  9. Mel says:

    Easiest way for me was to pour a little red wine in a glass and cover it tightly with wrap then poke a bunch of small holes in the plastic with a toothpick… The flies flew in and were unable to get out. They died happily in a bunch of wine! What better way to go!

      Hey Mel! Its much better ;) I think I wouldnt mind it either lol :P Hehe thanks for leaving a comment, have a good one!

    How do get rid of fruit flies. very good article

    • Natasha Anderson says:

      Hey Judy! Thanks for your kind words! I have an entire article that answers that exact question, you can find it under the fruit flies category at the top of this blog. If you have any further questions, please feel free to contact me :)

  11. amy says:

    hi
    The only thing about all of this is this never ends. You an catch them in these traps but when is it over. I am going crazy with these. I have traps all over but they still keep coming. I have cleaned scrubbed, did the drains you name it I have done it. I am ready to move out!

    • Natasha Anderson says:

      Hey Amy. Do not despair, you will win this battle. Fruit flies always congregate when they have a viable food source. Eliminate that and they will eventually leave. I recommend that you try and find their source of food. Start outside and make sure all your rubbish bins are properly sealed and secure. Keep me updated :)
