Those tiny «gnats» you see circling an overripe banana on your kitchen counter? They’re not gnats at all. They’re fruit flies. And they’re not only annoying but can be bad for your health. But there are plenty of ways to make them go away for good.
Where Fruit Flies Come From
No matter where in the U.S. you live, fruit flies can show up on your kitchen counters or inside your trashcan. They can turn up any time of year but are most common in the late summer and early fall. That’s because they’re attracted to ripe and rotting food.
Fruits and vegetables — especially bananas, melon, tomatoes, squash, and apples — are their favorites. Rotten onions and potatoes are also a big draw for these tiny, 1/8-inch-long creatures.
An adult female fruit fly can lay up to 2,000 eggs on the surface of anything that’s moist and rotting. Within 30 hours, tiny maggots hatch and start to eat the decayed food. Within 2 days, they’re all grown up and ready to mate, too. While that transition may seem quick, a fruit fly only lives 8 to 15 days.
Why Fruit Flies Are a Health Risk
Research shows that fruit flies can transfer germs from a dirty surface onto a clean one. Some of the bacteria they may carry include salmonella, E. coli, and listeria. These three germs each cause food poisoning. Severe cases may put you in the hospital and can even be life-threatening.
How to Get Rid of Them
If you have a fruit fly problem, insect sprays will kill the adult insects but won’t stop eggs from hatching. To get rid of all the fruit files in your home, you’ll need to:
Look for places where fruit flies can breed. Check for and clean up sticky spills or rotting food on your counters, inside drawers and cabinets, inside and under your refrigerator, and under other kitchen appliances. Aside from overripe fruit and veggies, fruit flies can lay their eggs on cleaning rags and mops, and even in empty cans.
Clean your drain and garbage disposal. You can pour boiling water into them or tape a clear plastic food storage bag over the top and leave in place overnight. Adult fruit flies will try to leave the drain, and you’ll find them in the bag in the morning.
Make a trap. Place 3/4 of an inch of apple cider vinegar or white vinegar with a scrap of fruit (like an apple core) into a lidded plastic container. Cut a dime-sized hole into the lid, then place a funnel into it. You can also fashion a funnel from a rolled-up piece of paper. Make sure there’s some room between the bottom of your funnel and the vinegar. Place the finished trap anywhere you’ve seen fruit flies. Once the sweet smell lures them into the container, they’ll get stuck in the vinegar.
Use bug spray with caution. If you do want to try an insect spray or fog, remember that they contain poisonous chemicals. Carefully read the label and follow the safety guidelines. Keep away from children and animals.
How to Stay Free of Fruit Flies
To prevent fruit flies from getting too comfortable in your house again:
Buy only what you’re sure you’ll eat. One spoiled potato or forgotten box of berries can lead to thousands of fruit flies. Once produce gets ripe, put it in your refrigerator until you eat it. Compost the leftovers or throw them away promptly.
Empty your kitchen trash can every day. When you do, clean up any spills, since these can attract fruit flies, too.
Rinse your recycling. Make sure all jars, bottles, and cans are free of food scraps.
Put screens on your windows and doors. Look for tight-fitting, 16-mesh models that can keep adult fruit flies from coming inside your home.
Turn off lights over your doors and windows. Light attracts newly adult fruit flies.
Seal all containers. If you preserve your own fruits and veggies or brew your own cider or beer, check that your lids are well sealed. If not, fruit flies can squeeze under them and lay eggs.

How to Finally Get Rid of Fruit Flies
You probably already have all the stuff you need to wipe them out.
Of all the household pests that might invade your home, fruit flies aren’t the worst. They’re not going to poison you, they’re not especially disgusting to look at, and they scare off with the flutter of your hand—temporarily, at least. Still, they can make you feel a little ashamed, like you have an unclean home, and they’re certainly annoying.
First, a little good news: Flies aren’t necessarily your fault. “It’s not a cleanliness issue. Flies can come in on your produce when you bring your groceries home,” says Melissa Riker, who blogs home tips at the Happier Homemaker. “And they are incredibly hard to control once you have them in your home because they can lay eggs on anything, even the smallest little crumbs. And they can get in your drains and lay eggs.”
How unpleasant to think about. Luckily, there are plenty of steps you can take to prevent fruit flies from settling in, to get rid of them once you have them, and to prevent them from coming back. Here are a few methods:
Rinse your fruit.
When you bring home fresh produce from the grocery store or market, wash it off before storing or displaying it. “You could just rinse it with water, or you can use one of those fruit and vegetables washes that they sell, or you can just use vinegar and water,” says Riker.
For that vinegar wash, Riker mixes around two parts water to one part vinegar, and notes that the combination might also keep your food from rotting a little bit longer as it kills some bacteria. Make sure to give your fruits and veggies one more final rinse in water before you’re done, though, so the vinegar flavor and scent don’t stick around.
Create a jar trap.
If the little suckers have already infiltrated, here’s one way to kill them. “I would take like a jar and put something that’s going to attract them inside,” says Riker. Fruit flies like sweet, rotting, fermenting things, so you could try over-ripe fruit, old wine, stale beer or soda, or apple cider vinegar. “Put that in the jar, and cover the jar with plastic wrap and poke a couple of small holes. They can get in and they can’t get out,” she says.
Riker suggests placing a few of these jars around your home, perhaps near sinks, cabinets, or the trash, if the problem’s gotten bad and you want to guarantee wiping them out asap.
Or stage a dish trap.
Another way to kill the flies is by. drowning them. “For that, you would use the apple cider vinegar or the wine or the beer as well, but you would add three drops or so of dish detergent,” Riker says. “Put it in a saucer, so it’s wide, because then once they come down to it, the detergent breaks the surface tension and they drown.”
Try a store-bought product.
There are insect sprays and repellants you could spritz around your kitchen, as well as sticky fly paper and plastic traps. But Riker hasn’t tried them, she says, because, honestly, “I feel like the apple cider vinegar really does the same thing. It just attracts them and traps them.” You probably already have all the stuff you need to fix the problem.
