Produce & spills.
- Overripe fruit, plus forgotten potatoes and onions
- Juice or food spills under the fridge and appliances
Fix: eat it, refrigerate it or toss it outside. Cut away bruised spots.

Finding the breeding spot matters more than the trap.
What actually works / step 02
What actually works.
The larvae live in a moist film of fermenting food. Find every spot like that and the flies run out of nurseries.
Drains & disposal.
- The slimy film in slow or rarely used drains
- The disposal and its rubber splash guard
Fix: scrub, then treat (step 04). Running water alone won't clear it.
Bins & damp stuff.
- Trash, compost and recycling bins
- Unrinsed wine and beer bottles and cans
- Damp sponges, dish rags and mops
Fix: empty and wash the bins, rinse the bottles, and wring everything out to dry.
Tiny flies over potted plants? Those are usually fungus gnats, not fruit flies. Let the soil dry out between waterings.
What actually works / step 03
DIY traps that work.
Traps catch the adults. They won't stop new ones while a breeding spot is still around.
the classic vinegar trap
2 minutes · 3 ingredients
Cider vinegar + a drop of soap.
- Pour about ½ inch of apple cider vinegar into a small jar.
- Add a drop of dish soap so the flies sink.
- Cover with plastic wrap, add a rubber band and poke a few tiny holes.
- Set it where the flies hang out. Refresh it every few days.
Paper-cone trap: roll paper into a cone with a tiny opening (under ¼ inch). Tape it into a jar baited with a piece of ripe banana, a splash of red wine or some beer. The tip shouldn't touch the bait.
Finish the catch by putting the trap in the freezer overnight. Swap out the bait every few days so it doesn't become a nursery itself. Keep traps away from pets and kids.
What actually works / step 04
Treat the drain, don't just rinse it.
If flies keep coming back after the counters are clear, the drain is the usual suspect.
test it first
Is it the drain?
Tape a clear plastic bag over the drain overnight. If there are flies in the bag in the morning, they're breeding in there.
1. Scrub it
Turn off power to the disposal first, and never put your hands inside it. Use a stiff drain brush on the pipe walls and under the rubber splash guard.
2. Treat it
Use an enzyme or bacterial drain gel or foam, following the label. It's usually poured at night when the sink isn't in use, and repeated for several days. Pouring boiling water slowly down the pipe walls can also loosen buildup. Skip it with PVC pipes, or if your sink or disposal maker says not to.
3. Check every drain
Also check bathtubs, floor drains, little-used sinks, and drip pans under the fridge.
Never mix drain products. Combining cleaners, especially anything with bleach or ammonia, can release toxic fumes. Bleach and ammonia don't help with flies anyway.
What actually works / step 05
Stick with it for 1–2 weeks.
One female can lay about 500 eggs, and egg to adult takes roughly 8–10 days. Keep the habits going until a full cycle passes with no new flies.
three daily habitsSmall habits.
Small habits.
No nurseries.
Refrigerate ripe fruit. Take the trash out every day. Rinse recyclables before they go in the bin.
Day 1
Clear the breeding spots, scrub and treat the drains, and set traps.
Days 2–7
Keep up the habits. Refresh the trap bait and repeat the drain treatment per the label.
Days 8–14
You should be catching fewer and fewer flies. By now, a full life cycle has passed.
Still flying?
A source is still out there. Recheck the bins, drains and under the appliances, or ID the fly below.

One last useful clue
Know your tiny troublemaker.
The fix depends on the fly, and these three get mixed up all the time.
Fruit fly
Usually tan or brown, often with reddish eyes. Look near ripe fruit, beverages, trash, or other fermenting residue.
Drain fly
Fuzzy, moth-like wings. Often found resting near sinks, showers, or drains with a wet organic film.
Fungus gnat
Dark, slender, mosquito-like. Often hovers around damp potting soil in houseplants.
