Quick answer. Remove the fruit and the bin juice, then a jar trap with apple cider vinegar and a drop of soap.
Sprays do not beat the bowl of bananas and the recycling bottle.
MarketPalace Guide Center writes this as a solution walkthrough — the order we would use if we were in the room with you. We name the next click, then what to do if that click fails. We do not sell the TV, the kettle, or the plane ticket.
If a menu name on your set or phone does not match, use the closest wording and email hello@marketpalace.shop. We correct live pages when the path has moved.
What you need
- Cider vinegar
- Jar
- Dish soap
In this guide
1. Throw out overripe fruit and rinse bottles
Empty the under-sink bin.
2. Set a jar: vinegar, drop of soap, plastic wrap with holes or a paper funnel
They go in and do not come out.
3. Wipe the bin rails and the drain
A splash of boiling water in the drain helps.
4. Keep the trap two or three days
One night is not enough.
If it still fails
- This is household pest control, not a medical guide.
When you are done, browse more in Home & Fixes or search the Guide Center for the next job on your list. A neighbour problem — a remote, a bill, a suitcase — has its own walkthrough.

Drain flies sit on the bathroom wall and breed in the overflow. A drain gel is for those.
