What to do if there are always sowbugs in the bathroom?
Bathrooms are a favorite place for sowbugs—dark, damp, and with drains as an entry point. Management requires addressing both plumbing and humidity.
Check and seal pipes
Many sowbugs crawl up from the drains; plumbing treatment is the first step:
- Check for damaged or poorly sealed floor drains. Replace old ones with insect-proof types (with spring or magnetic seals).
- Ensure the pipe connections under the sink are tight; seal any gaps with caulk.
- Check if the toilet's wax ring is old or loose.
- Keep floor drains and openings closed when not in use.
Apply insecticide
- Evenly spray the bathroom floor and corners with bifenthrin-containing household hygiene insecticide.
- Focus on areas behind the toilet, under the vanity, and around the floor drain.
- Once dry, it forms an invisible film. Sowbugs crawling up from the drain or across the floor will die.
- Lasts 2-4 weeks; one application lasts a long time.
Keep it dry
- Run the exhaust fan for 15-20 minutes immediately after showering to remove moisture.
- Pull the shower curtain open to allow ventilation; don't leave it bunched up and damp.
- Wipe up floor water with a squeegee or mop.
- Wring out mops after use and hang them to dry; don't leave them wet on the floor.
Seal cracks
- Check for cracks in corners and floor tiles; fill them with grout.
- Seal the joint between the sink and the wall with silicone caulk.
- Reduce hiding places and entry routes for sowbugs.
