Gaps behind cabinets and along baseboards can provide convenient hiding places.
These conditions can support silverfish, especially moisture-associated species.
How to make a bathroom less attractive
Use an effective exhaust fan during showers and allow it to run long enough to remove excess moisture.
Repair leaking taps and pipes.
Dry persistently wet surfaces when practical.
Inspect the area beneath sinks and around toilets for signs of leaks.
Seal appropriate gaps around plumbing and baseboards.
If humidity remains high, a suitable dehumidifier may help, depending on the room and ventilation system.
These measures can reduce favorable conditions for moisture-associated pests, although they may not eliminate silverfish that are living elsewhere in the building.
