why do we have fruit flies in our house

Have you ever found your kitchen teeming with fruit flies that seemed to appear out of nowhere? These tiny nuisances can quickly multiply in number, and be tough to get rid of once they re around. So how did these fruit flies get in your kitchen? Contrary to popular belief, this isn t a case of spontaneous generation. Fruit flies are built to find fermenting fruit. Through small, they can detect the smell of ripe fruits and vegetables from a good distance away. If there s a bowl of fruit on your kitchen counter, there s probably a fruit fly or two looking for a way into your home to get to it. Because these insects are so tiny, they can
around windows or doors. Once inside, they reproduce. Before you know it, you ve got yourself a full-fledged fruit fly infestation (say that 5 times fast! ). Sometimes, fruit flies hitch a ride into your home on fruits or vegetables.

Fruit flies lay eggs on the skin of very ripe or fermenting fruit. Those bananas you brought home from the grocery store may already harbor a new generation of fruit flies. If you let your tomatoes over ripen on the vine before picking them, you may be harvesting fruit fly eggs along with your crop. Unrefrigerated fruit, whether its on display in the grocery store, still in the garden, or sitting in a bowl on your kitchen table, may attract fruit flies. Fruit flies have notoriously fast life cycles; they can go from egg to adult in just 8 days. That means one overly ripe tomato left unused on your counter can give rise to a small fruit fly swarm within a week. Fruit flies are also known for their persistence once indoors. PAlthough a female fruit fly adult will only live about a month at best, in that short time, she can lay 500 eggs.

PThey don t even need fruit to keep reproducing. Fruit flies can breed in the slime layer inside slow-draining plumbing, or on an old, sour mop or sponge. So you can get rid of all your fruit, but still find your home infested with fruit flies. Have a fruit fly infestation now? You ll need to eliminate all possible food sources and make your home inhospitable to breeding adult fruit flies. PTry to catch breeding adults quickly. Then follow these to eliminate them for good. Fruit flies need very little to call your kitchen their home, sweet home. All that they require is a moist area of fermenting stuff. That stuff can be ripened fruits or vegetables, as well as drains, garbage disposals, empty bottles and cans, trash bags, or cleaning rags and mops.

Fruit flies lay their eggs up to 500 at a time on these moist surfaces. When the larvae hatch, they feed on the surface too. Because they only feed on the surface, you probably won t eat any of the insects if you just toss out the damaged or over-ripened parts of fruits and vegetables. Because the flies are so teeny, they can sneak into houses as adults through window and door screens or on fruit as larvae. To keep flies out of your kitchen, University of Kentucky entomologists recommend building a homemade flytrap. Roll a paper funnel into a jar. Pour a few ounces of cider vinegar into the jar, or put a ripe, peeled banana in it. Once you ve caught the flies, you can kill them, or animal lovers can release the critters outdoors.
