“They came out of nowhere!” is the most common reply I hear from our customers when dealing with fruit flies. Fruit flies can be a problem year round, but are especially common during late summer/fall because they are attracted to ripened or fermenting fruits and vegetables.

Fruit flies are especially attracted to ripened fruits and vegetables in the kitchen. But they also will breed in drains, garbage disposals, empty bottles and cans, trash containers, mops and cleaning rags. All that is needed for development is a moist film of fermenting material.

“But all my doors and windows are closed,” you say! “How in the world could they possibly get in?” Fruit flies are so tiny that they can enter through even the tiniest of crevices around windows or doors and can even fly right through your window’s insect screen. You see, when a fruit is overripe or starts to go bad it begins to ferment, producing alcohol, which attracts fruit flies. They continue to gobble up the fermenting fruit, and in the process, lay hundreds of eggs which hatch into larvae in mere hours. If you ever went out of town and left a bowl of ripe fruit on the counter, then you know this all too well.

Once the invasion starts it is paramount the source is located. When located, remove the item from the home and place it in the outside garbage can. Discarding it to the interior garbage can will only exacerbate the problem. Fruit flies are primarily nuisance pests, however, they also have the potential to contaminate food with bacteria and other disease-producing organisms.

By the way, you can even bring fruit flies home from the store with your groceries if the fruit has already started to rot there.
