One fruit fly is a curiosity. Twenty hovering over the fruit bowl is an invasion — and swatting does nothing, because for every fly you see, eggs are already hatching somewhere you haven’t looked. The good news: fruit flies are one of the easiest kitchen pests to beat, and it takes no chemicals at all. You just have to find the breeding source, trap the adults, and cut off the food supply. Do it properly and your kitchen is clear in about three days. Here is exactly how to get rid of fruit flies.
Fruit Flies at a Glance
| Question | Quick answer |
|---|---|
| What do fruit flies look like? | Tiny (about 3mm), tan-brown, with red eyes — slow, hovering flight |
| Where do they breed? | Ripe and rotting fruit and vegetables, plus slimy drains, mops, sponges and recycling |
| How fast do they multiply? | Eggs hatch in about 24 hours; egg to adult in 8–10 days in a warm kitchen |
| What actually works? | Remove the source + apple cider vinegar traps + a drain clean |
| Not sure they’re fruit flies? | Flies breeding in the drain itself are drain flies; tiny black flies around houseplants are fungus gnats — different fixes |
Step 1: Find and Remove the Breeding Source
Traps catch adults; only source removal ends the problem. Start with the obvious: the fruit bowl. Move sound fruit into the fridge for now, and throw out anything overripe, split or forgotten — bananas with brown spots and tomatoes past their best are fruit fly nurseries. Then hunt the hidden sources people miss: the onion or potato that rolled to the back of a cupboard, the recycling bin with juice and wine residues, a damp mop or sponge, the drip tray under the fridge, and spills under appliances. Empty and rinse recycling, wring out and dry mops and sponges, and wipe down counters, the bin and the area around it. If the flies seem to rise from the sink itself rather than the fruit, you may have their cousins instead — see our guide on how to get rid of drain flies, because those breed inside the drain.
Step 2: Trap the Adults With Vinegar
While the next generation is being cut off, mop up the flying adults. Pour a few centimetres of apple cider vinegar into a jar or bowl, add one drop of dish soap, and stir. The vinegar smells like fermenting fruit — irresistible — and the soap breaks the surface tension so flies that land, sink. Set traps beside the fruit bowl, the sink and the bin. For a tidier version, cover the jar with cling film, secure it with a band and poke a few small holes: flies walk in and can’t find their way out. Empty and refresh traps daily; within two to three days the catch should fall to almost nothing. If it doesn’t, a breeding source is still hiding somewhere — go back to Step 1.
Step 3: Clean the Drains and the Damp Spots
Fruit flies also breed in the thin slime that coats sink drains and overflow channels. Scrub the drain rim and stopper with a bottle brush, flush with hot water, and finish with a kettle of freshly boiled water poured slowly down the drain. Repeat for a few evenings if your infestation was heavy. Wash or replace old sponges, launder the dish towels, and let the mop dry fully between uses — a permanently damp mop head is a five-star fruit fly hotel. If tiny black flies are also hovering around your houseplants, those are a separate pest with a soil-based fix — our guide on how to get rid of gnats covers them.
Step 4: Keep Them Gone
Prevention is boring and total. Store ripe fruit in the fridge during warm months, or under a fine mesh cover if it must stay out. Rinse bottles and cans before they go in the recycling, keep the bin lidded and emptied, wipe juice and wine spills the day they happen, and rotate the potatoes and onions so none age in the dark. Check new fruit when it comes home — one split peach in the bag is how most infestations arrive. Follow this for two weeks and the occasional scout fly that wanders in will find nothing to start a family on.

FAQs About Getting Rid of Fruit Flies
How long does it take to get rid of fruit flies?
With the breeding source removed and vinegar traps running, most kitchens are clear in about three days. A tail of a week means one hidden source — usually a drain, a forgotten potato, or the recycling — is still feeding them.
Why do fruit flies keep coming back after I trap them?
Traps only catch adults. If eggs and larvae still have a food source, new adults replace the trapped ones every day. The fix is always the same: find and remove what’s fermenting.
What’s the difference between fruit flies and drain flies?
Fruit flies are tan with red eyes and hover around fruit and food. Drain flies are darker, fuzzy and moth-like, and breed in the slime inside drains — if yours emerge from the plughole and rest on the tiles nearby, treat the drain, not the fruit bowl.
Does apple cider vinegar really work on fruit flies?
Yes — it’s the best DIY trap there is. The drop of dish soap is the crucial part: without it, flies land, drink and leave; with it, they sink. Refresh the trap daily for best results.
Can fruit flies make you sick?
They can carry bacteria from bins and drains onto food, which is reason enough to act fast — but the main issue is contamination and sheer numbers, not disease. Food they’ve swarmed over should be thrown away.
