Shower flies, also known as drain flies, can become a persistent nuisance in bathrooms. They breed in the thin biofilm that lines drain pipes and traps. This guide provides practical, step-by-step methods to reduce and eliminate shower flies using common tools and products available in American homes and stores.
By following a structured approach—clearing clogs, cleaning drains, and adopting preventative habits—most households see a noticeable drop in activity within days. The emphasis is on safe cleaning practices, effective products, and simple maintenance routines that fit into a typical household schedule.
Quick Answer
To stop shower flies fast: combine thorough drain cleaning with a drain trap and regular maintenance. Use enzyme or bacterial cleaners to break down organic buildup, and physically remove hair and debris from the drain. Seal or cover drains briefly after cleaning to prevent re-entry of adult flies.

- bathroom drain fly trap with bait
- enzyme drain cleaner for bathroom shower drain 32 oz
- drain snake plumber’s auger 1/4 inch x 25 feet
- bacterial drain cleaner shower drain 64 oz enzyme

Step-By-Step: How To Get Rid Of Shower Flies
- Identify the primary breeding drain by watching where flies emerge most; start with the shower drain first.
- Clear visible hair and debris from the shower drain using a shower drain hair catcher with adjustable grid.
- Apply an enzyme drain cleaner for bathroom shower drain 32 oz into the affected drain to break down organic buildup.
- Follow with a bacterial drain cleaner shower drain 64 oz enzyme to sustain ongoing degradation of biofilm.
- Run hot water for several minutes to help the cleaners circulate and reach deeper sections of the pipe.
- If clogs persist, gently insert a drain snake plumber’s auger 1/4 inch x 25 feet and rotate to dislodge dense buildup.
- Place a bathroom drain fly trap with bait near the drain to capture newly emerged flies.
- Rinse the drain again and observe activity over the next 48–72 hours for additional treatment needs.
- Repeat enzyme/bacterial treatments weekly for 2–4 weeks during high humidity seasons.
- Keep the drain cover closed when not in use to prevent adult flies from entering the bathroom from the drain.
- Monitor nearby drains (sink and tub) for signs of infestation and treat if necessary.
- Maintain a regular cleaning schedule and replace the hair catcher grid as it wears out.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent fly activity after treatment | Hidden drain clusters or missed drains | Repeat enzyme/bacterial cleaners; check other drains | Regular maintenance; seal unused drains |
| Smelly drain even after cleaning | Biofilm deeper in the pipe | Extend treatment duration; flush with hot water | Weekly enzyme cleaning |
| Hair catcher grid quickly clogged | Excess hair buildup | Clean more often; replace grid | Brush hair away during showers; use grid |
| Drains re-infested within days | Inflow from other fixtures | Inspect adjacent drains | Keep lids closed; routine maintenance |
Common Mistakes
- Using bleach or harsh chemicals alone, which may not address biofilm and can damage pipes
- Ignoring other nearby drains that can harbor flies
- Rushing the process without letting enzymes and bacteria work
- Failing to replace worn hair-catcher grids, allowing hair to accumulate again
Tips For Best Results
- Use enzyme and bacterial cleaners in alternating cycles to target different layers of buildup
- Keep the bathroom well-ventilated during cleaning to reduce lingering odors
- Install a high-quality shower drain hair catcher with an adjustable grid to intercept hair before it enters the drain
- Schedule monthly maintenance checks for drains in humid seasons
- Label and store cleaners safely out of reach of children and pets
Call A Professional
If drain flies persist after two to three treatment cycles or infest multiple plumbing fixtures, consider contacting a licensed plumber. Signs to seek help include strong persistent odor, repeated clogs, or drains that refill quickly after flushing, indicating more complex pipe issues.
FAQ
What causes shower flies to appear?
Shower flies breed in organic debris and biofilm in drains, especially in warm, damp environments.
Are drain fly traps effective long-term?
They help capture adults but do not treat the underlying infestation; combine traps with enzymatic cleaning for best results.
Can I use household bleach to eliminate drain flies?
Bleach can kill some organisms but may not remove biofilm; enzyme and bacterial cleaners are more effective long-term.
How often should I clean my drains to prevent future infestations?
Perform routine maintenance every 4–6 weeks, with more frequent cleaning during humid months.
Buying Guide
When selecting products to combat shower flies, consider these factors to ensure effective results and ease of use.
Size and scope

Opt for user-friendly products that are simple to deploy, with clear instructions. Some traps are discreet and quiet during operation.
Energy efficiency and safety
Enzyme and bacterial cleaners operate without high energy usage. Follow all safety guidelines to avoid chemical exposure.
Controls and application
Look for cleaners that are easy to apply into the drain and have clear dosing instructions. A drain snake is useful for stubborn clogs.
Placement and compatibility
Ensure products fit your shower drain size and are suitable for home bathroom use. Consider a hair catcher that matches your drain’s grid design.
