Quick answer: Fruit flies are tiny tan flies with red eyes that breed in fermenting fruit, spilled sugary liquids, and the organic film inside drains. Getting rid of fruit flies means finding and eliminating the breeding source — overripe produce, recycling residue, and drain gunk — because sprays never fix the source.
What do fruit flies look like?
Fruit flies are tiny — about 1/8 inch — and tan to brownish, and the common species have bright red eyes. They are slow, hovering fliers usually seen near fruit bowls, trash, recycling, and sink drains.
Signs of a fruit fly problem
The main sign is small flies hovering around ripe produce, bins, or drains, often appearing suddenly and in growing numbers. They breed fast, so a few can become many within days.
Where fruit flies breed
Fruit flies lay eggs on fermenting organic material: overripe fruit and vegetables, spilled sugary liquids, damp mop heads, and the slimy organic film that builds up inside drains and around recycling containers.
How to get rid of fruit flies
Control is source elimination: discard or refrigerate ripe produce, wipe up spills, empty and rinse recycling and trash, clean under and behind appliances, and scrub or treat drains to remove the breeding film. An apple-cider-vinegar trap catches lingering adults, but it is a supplement — finding the source is the fix.
When to call a professional
Persistent fruit flies usually mean a hidden breeding source. A professional can pinpoint drains, voids, and equipment harboring the material and treat them — especially valuable for bars, kitchens, and food service.

Fruit Fly FAQ
How do I identify fruit flies?
Fruit flies are about 1/8 inch, tan to brownish, and most have bright red eyes. They hover around ripe or fermenting fruit, recycling bins, and drains.
Where do fruit flies come from?
They breed in fermenting organic material: overripe fruit and vegetables, spilled juice, beer, wine, and the moist film inside drains and around recycling bins.
How do you get rid of fruit flies?
Remove or refrigerate ripe produce, clean up spills, empty and rinse recycling, and scrub drains to remove the organic film where they breed. A vinegar trap helps catch remaining adults, but eliminating the source is what solves it.
Why do fruit flies keep coming back?
Because the breeding source is still present. Even a small amount of fermenting residue in a drain, under an appliance, or in a recycling bin can sustain a population.
Are fruit flies harmful?
They are mainly a nuisance and a sanitation concern; because they move between waste and food they can transfer bacteria to food surfaces.
