How You Know You Have a Silverfish Problem
Other than the obvious — seeing one wiggle across your floor — silverfish signs may include:
- Yellow stains or little holes on paper or fabric.
- Shedded skin – Silverfish molt and leave a little shell behind.
- Droppings – Little black, peppery drops in dark corners.
- Wallpaper damage – Often along seams and corners.
If any of these signs appear in a damp area in your home — you have silverfish.

Getting Rid of Silverfish in Your Home
So what now? You’ve identified them and are packing them up. Here’s how:
1. Dry the Environment
Silverfish cannot live in dry conditions. A dehumidifier is a good idea — particularly in basements and bathrooms. Air must circulate. Ventilation is key.
