Flies and drain flies: why they breed and how to stop them
House flies breed in garbage and rotting food; tiny drain flies breed in the slimy film inside sinks and bathroom drains.
- Drain flies come from the drain itself — cleaning the drain is key.
- Flies carry germs from garbage to food.
- Treatment targets both breeding spots and resting spots.
Signs to look for
- Small, furry, moth-like flies near bathroom and kitchen drains.
- House flies around bins, food and windows.
- Larvae in garbage bins or wet waste.
Why they come — and why it matters
- Wet garbage, food waste and organic film in drains and sink traps.
- Rarely used bathroom drains that dry out or build up slime.
- Flies can spread germs to food and kitchen surfaces.
What you can do at home
- Pour hot water down sink and bathroom drains and scrub the drain mouth weekly.
- Keep wet waste in a closed bin and empty it daily.
- Clean under the fridge and behind kitchen appliances.
- Fit mesh on windows near garbage areas.
When to call a professional
- Flies keep returning after drain cleaning.
- You run a restaurant, café or food business.
- There's a garbage collection point near your home.

Common questions
What are the small moth-like flies in my bathroom?
Those are drain flies, also called moth flies. They breed in the slimy film inside drains and floor traps, which is why spraying the air does not get rid of them.
Why do flies come back after I clean?
Surface cleaning does not reach the build-up inside drain pipes, floor traps and sink pipes where the larvae live. Treatment targets that breeding film.
