Where Do Fruit Flies Come From?


Summary: Fruit flies are common pests of kitchens, but where do fruit flfies come from? The short answer is that fruit flies breed in any forgotten place where food material has slipped between cracks to decompose or where fruit has been left out too long.

James R; Johnstown, PA asks: I getting a lot of fruit flies in my kitchen during the summer. Where do fruit flies come from?

Dear James: To answer your question, "Where do fruit flies come from?", my suggestion would be that the fruit flies are coming in to your home on the fruits and vegetables that you are bringing in from the garden, grocery store or farmer's market. It's very common for this to occur during the warm summer weather.

Wash your fruits and vegetables when you bring them into the house. You can use a product like Veggie Wash if you are worried about removing waterproof pesticides. Or, refrigerate them. Either way, you want to remove the breeding source for the flies.

Ripe, soft fruits like bananas, peaches, pineapple and strawberries are some of the most frequent breeding sources for fruit flies. Once you remove the

breeding source the fruit flies will be gone within hours. They have a very short life span so you won't see lots of breeding adult flies if they have nothing to eat or nothing to lay their eggs in.

A quick shot of any flying insect killer like Raid Flying Insect Killer will also do the trick for the adult flies. But, if you don't get rid of the breeding source you'll have the flies back in full force within a day or so.

I don't know if these are fruit flies, they are real small and I even think i had them in the winter. I don't buy bananas anymore for that reason. Do houseplants bring them in?

Houseplants surely breed small flies and gnats. Allow the soil to dry out for a few days. Lack of moisture will kill off any soil breeding flies.

A great way to get rid of those pests is poor some apple cider vinegar in a small container add a few drops dish detergent, mix and you'll be amazed at how many you collect.

It's summertime. Flies flourish in the heat. They can lay their eggs at the base of stems or in the hole where the stem has been removed. Thoroughly wash fruits and vegetables as soon as they come inside the house. These flies will hatch in hours and are capable of laying eggs in only a number of hours after emerging as adult flies.

I have a worm farm in Texas. Recently I tried a new bedding mix and now I have some sort of soil breeding fly infesting my barn. It looks kinda like a flea with wings, fruit fly I assume. How can I eliminate the fly without killing my worms?

The flies have to be breeding in some type of decaying matter. It could be around the yard or near where you park the truck. If you don't want to apply pesticides you might consider the the Mini Silo Fly Sentry (http://shop.asktheexterminator.com/flies/mini-silo-flysentry.html) and Maxforce Fly Spot bait (http://shop.asktheexterminator.com/flies/maxforce-fly-spot-bait-bottle.htm l). Hand the silo outside near the fly activity.

Fruit flies breed in decomposing materials. Finding the source is a matter of careful examination of your kitchen surfaces. Touch things to see if they are totally clean. Sides of the stove. Refrigerator doors. Air filter over the stove. Inside of garbage cans.

I just renovated my kitchen a couple of months ago. Everything is brand new, but now we have fruit flies. Not only in the kitchen but in other rooms. Yes, the traps work to catch them, but it doesn't eliminate them. I don't know where to look to find the breeding source. Help!

I understand to get rid of fruit flies is to find the source but what if I can't find the source. My house is covered with millions of them. They are in every room in my house. My daughter has a million on her windows. One minute they are in one place and then later I'll find alot of them somewhere else. If I put the air conditioners on in my house will they go away.

I have a problem with fruit flies in my bathroom and bedrooms and near the kitchen windows since last Thurs..They are all near the windows and they go on the mirrors..There are so many..I have never ever had this problem and I have lived in my home for 20 years..Please help Im desperate..What can I do and what can be causing these fruit flies to come..They are not coming out of the drains and we donot eat in the bathrooms or bedrooms. There seem to be alot by the windows and I have kept my windows closed and look to see where their coming from but cannot find where they are coming from

Flies move towards the light, so the windows have nothing to do with fly breeding. I would also guess the flies are not fruit flies, but Phorid flies. These flies breed under the floor tile or behind the tile walls of the shower. Tiny cracks in the grout allow moisture to accumulate under the tile, creating a breeding area for the flies. Revmoving the tile and drying the surface under the tile is the best solution.

well, I have done a thorough cleaning of my house and still have not found the source. I am lucky that I can say I don't have "millions" of these things. There always seem to be just one buzzing around. I see about 3 or 4 every day in different rooms. Sometimes I am successful at smaking them to death between my hands. I have gotten rid of the traps (they were too gross) and I've search everywhere for the source. I have two small children so I was hoping to find an apple core under their bed or something, but I didn't. My husband thinks I am obsessing over nothing. He claims he hasn't seen any in days. I wonder if I should just give up.

I've been heeding your advice and trying to locate the breeding source of my fruit flies, but have not found any decaying/rotting food anywhere. Could they be breeding in my trash can if I don't empty it every day? If I empty it, say, every other day, could this give them enough time to breed in there?

Small flies can breed in as little as 10 to 20 hours in warm conditions. The garbage can should have a liner. Check the bottom of the can to be sure it is not sticky to the touch. Check around the rubber gasket of the refrigerator, too. Touch everything for sticky surfaces.

I fertilized a home plant with compost, and the fruit flies are breeding there clearly. No matter how many traps, sticky fly paper I put up, they do not disappear. Will it help just removing the compost layer from the plant, or what else can really be done about this problem which has persisted for a couple of months. They don't seem to move to other plants I also feed compost.

I have these (nats, flies?)that hover on the outside of my kitchen window. They eventually make it inside the outside and annoy me! I have never seen or heard of this before. Any idea?

The drain beneath the sink appears to have ruptured and now the soil beneath it is infused with rotting food material. How can I neutralize this area to make it unsuitable for fruit fly breeding?

I scrubbed down my kitchen and bathroom with bleach.....Had my boyfriend pull out my appliances as well.....I still have at least a hundred a day....I threw out everything in my refrigerator and scrubbed that out as well.....I treated my drains and even washed all the walls down but still these little buggers keep coming....I use a mixture of Martini Austi and dish soap to trap them (lol, I think they like the wine as much as I do if not more) but seriously now, if you clean everything, seems the only choice left is to call an exterminator....what do you think?
