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.
