Fruit flies have a way of showing up when you least expect them. One day your kitchen looks perfectly clean, and the next, tiny flies are hovering around the fruit bowl, sink, trash can, and even your morning coffee.
A few flies can turn into a much bigger nuisance in a short amount of time. They’re usually harmless, but nobody wants to swat them away every time they walk into the kitchen.
You probably don’t need an exterminator to deal with a typical fruit fly problem. The first step is finding out where they’re breeding, then removing the food sources and catching the adults that are already flying around.
Find the Source Before You Do Anything Else
Getting rid of the adult flies won’t solve the problem if they’re still able to feed and lay eggs somewhere in your home. Overripe fruit is a common culprit, but it isn’t the only place to check.
Look for a forgotten potato in the pantry, a piece of spoiled produce behind an appliance, sticky spills under cabinets, or food residue inside an old container. Check your fruit bowl, pantry, trash can, recycling bin, and the spaces behind and underneath kitchen appliances.
Once you find the source, throw away anything spoiled and clean the area with soap and water. Pay attention to corners, crevices, and small spills that may have been missed during your regular cleaning.

Don’t Forget the Drains
If fruit flies keep appearing after you’ve cleaned the kitchen, check your drains. Food particles and other organic material can collect inside pipes and create a place for certain small flies to feed and reproduce.
Scrub the drain opening and any accessible buildup with a suitable drain brush or cleaner. An enzyme-based drain treatment made for organic buildup may help break down residue farther inside the pipe, but follow the product directions.
Check bathroom sinks, tubs, floor drains, and sink overflow openings, too. Covering a drain overnight can help you check whether flies are emerging from that opening, but it won’t remove the buildup causing the problem.
Avoid pouring boiling water into pipes unless the plumbing manufacturer says it’s safe, since high temperatures can damage some plumbing materials. Never mix bleach with vinegar, ammonia, or other household cleaners because the combination can release dangerous fumes.

Set More Than One Trap
An apple cider vinegar trap is an easy way to catch adult fruit flies. Pour some apple cider vinegar into a small container, add a few drops of dish soap, and place it near the area where you see the most flies.
The vinegar attracts them, while the soap breaks the surface tension so they have a harder time escaping. Set out several small traps around the kitchen rather than relying on just one.
Store-bought fruit fly traps are another option if you’d rather skip making your own. Many contain an attractant and can sit on a countertop without taking up much room.
Wine, beer, and other sweet liquids can also attract fruit flies. A covered container with small openings can let them enter while making it harder for them to get back out.
If adult flies are still around after you’ve removed the breeding source, indoor insect traps with UV lights and sticky pads may help catch some of them. Keep traps away from children, pets, and food preparation areas.

Check Your Houseplants
Those tiny flying insects in your kitchen might not be fruit flies at all. If you have several houseplants, you could be dealing with fungus gnats, which are often found around damp potting soil.
Fungus gnats tend to fly up when you water or disturb a plant. Let the soil dry out more between waterings if the plant can tolerate it, and avoid leaving pots sitting in trays of standing water.
Yellow sticky traps placed near the soil can catch adult gnats. For larger infestations, products containing Bacillus thuringiensis israelensis (BTI), such as mosquito bits, can help target larvae in the soil when used according to the label.
Remove dead leaves and other decaying plant material from the pots. Keeping the soil from staying constantly wet can make it less inviting to fungus gnats.

Clean the Places You Usually Miss
Wiping down the kitchen counters is a good start, but fruit flies can find food in places that are easy to overlook. Check around the garbage disposal, sink drain, refrigerator, dishwasher, trash can, and recycling bin.
Move small appliances and look underneath them for sticky spills or food crumbs. Wash reusable food containers after use, and rinse cans and bottles before putting them in the recycling bin.
During warmer months, store ripe fruit in the refrigerator when possible. Check produce when you bring it home and discard anything that’s already spoiled.
Take kitchen trash outside regularly instead of letting food waste sit in a full bag for days. A trash can with a tight-fitting lid can also help keep food odors from attracting insects.

Cut Down the Adult Flies
While you’re removing the source of the infestation, you can also get rid of some of the adult flies already buzzing around. A handheld vacuum can pick them up from windows, walls, counters, and other surfaces.
Empty the vacuum afterward so the insects don’t remain inside. An electric fly swatter can also help with individual flies that are difficult to catch.
A small fan may help around food preparation areas, too. Fruit flies are weak fliers, so moving air can make it harder for them to hover around fruit bowls and other spots where they gather.
Removing adult flies helps reduce the number left to reproduce, but it won’t replace the need to clean up their breeding sites.
Look for Ways They’re Getting Inside
If you’ve cleaned the kitchen, checked the drains, and set traps but still see new flies, look around doors, windows, vents, and other openings. Damaged screens and gaps around doors can let insects enter from outside.
Fine mesh window screens and vent covers can help keep flies out. A door sweep can also close the gap beneath an exterior door.
Check the area outside your home, too. Outdoor trash cans, compost containers, and fallen fruit from nearby trees can attract flies close to your doors and windows.
Give the Problem a Few Days
Fruit flies rarely disappear the moment you throw away one spoiled piece of fruit. Eggs and larvae may already be present, so it can take several days of cleaning and trapping before you notice a major difference.
Keep the traps in place, clean areas where organic material collects, remove spoiled food, and take out the trash regularly. If fungus gnats are coming from your houseplants, continue treating the soil until the adult insects stop appearing.
The goal is to remove the places where flies reproduce, rather than just killing the ones you can see. Once the breeding source is gone and the remaining adults have been caught, the problem should gradually fade.
Keeping ripe produce refrigerated, cleaning up spills, checking drains, and taking out food waste regularly can make your kitchen much less attractive to fruit flies.
