How to Get Rid of Drain Flies
Remove drain flies by cleaning the source, not just killing the adults resting on your walls.
Quick Answer: Fast Steps
1. Clean the drain thoroughly: Flushing with hot water is the first step.
2. Remove organic buildup: Use a pipe brush to physically scrub the sludge inside the drain.
3. Use the right drain treatment: Bio-enzymatic drain cleaners work best here.
4. Keep the area dry: Fix any leaks and wipe down standing moisture.
5. Repeat for several days: Ensure all larval cycles are broken.
What Are Drain Flies?
Also known as moth flies or sink flies, drain flies are small, dark, fuzzy insects. They are weak flyers and typically rest on the walls near sinks, showers, and damp basements. They are distinctly different in appearance and behavior compared to fruit flies.
What Actually Works vs What Does Not
What Works (Do This)
- Physical scrubbing of the drain pipe (Source cleaning)
- Bio-enzymatic drain cleaners (Eats the slime)
- Repeated cleaning regimens
What Does Not Work Alone
- Spraying flying adults only (Ignores the eggs)
- Setting random traps without drain cleaning
- Pouring bleach once (Bleach flows too fast to clean the sludge)
