Silverfish in the Bathroom: Moisture Clues and Fixes

Silverfish in bathrooms are a clue that damp is present.

The short answer

Bathrooms provide moisture, warmth and food such as soap residue, hair and paper. Improve ventilation, fix leaks, dry surfaces, seal cracks around tiles and pipes, remove clutter and store towels and tissue rolls off the floor. Keep drains clean. If silverfish remain, check hidden leaks.

Why bathrooms

• Humidity and leaks.
• Hiding places behind tiles and cabinets.
• Paper, soap residue and hair as food.

Fixes

1. Install or use exhaust fans.
2. Fix dripping taps and leaks.
3. Dry floors and walls after use.
4. Seal gaps around fittings.
5. Store paper items elsewhere.
