Fruit flies seem to appear from nowhere, but they're actually breeding in overlooked food sources in your kitchen. Eliminate those sources and you eliminate the problem.
Fruit flies breed in overripe fruit, the drain, spilled juice behind appliances, recycling bins, and even wet mops. You must find and eliminate every breeding source — traps alone won't work long-term.
Put all ripening fruit in the refrigerator. A single overripe peach or forgotten banana can sustain hundreds of fruit flies. Check for produce you've forgotten about.
Fruit flies breed in the organic film inside sink drains. Pour boiling water down the drain, then scrub with a bottle brush. Use a Bio-Clean drain treatment or enzyme cleaner weekly.
Place TERRO Fruit Fly traps or DIY traps (apple cider vinegar + a drop of dish soap in a cup covered with plastic wrap with small holes) near the breeding area.
Clean under and behind appliances. Wipe down all surfaces, especially under the toaster and coffee maker. Rinse recycling before it goes in the bin.
A forgotten potato, onion, or piece of fruit fallen behind a cabinet is a common overlooked breeding site for persistent infestations.
Keep fruit refrigerated during warm months. Empty recycling weekly. Run cold water through drains nightly. Problem solved permanently.
Primarily from eggs laid on ripening fruit before you buy it at the store. They can also enter through window screens. A single female lays 500 eggs — infestations grow fast.
They contaminate food with bacteria and yeast from breeding sites (including garbage and drains). They're more of a nuisance than a health risk, but fruit fly populations in commercial kitchens can trigger health code violations.
If you eliminate all breeding sources, you can eliminate a fruit fly infestation in 4–7 days. Traps without source elimination will just thin the population, not solve the problem.
Fruit flies are small (3mm), reddish-brown with red eyes. Drain flies (also called moth flies) are slightly larger with fuzzy, moth-like wings and breed specifically in drains and sewage. Both are solved by eliminating breeding sites.
Yes for catching adults, but they don't address the breeding source. You'll catch 50 fruit flies while 500 new ones are hatching in your drain. Always combine traps with source elimination.
