If left unchecked, silverfish can cause significant damage, especially to:
Books & paper – They’ll eat the glue and the pages. Clothing & linens – Long-stored items are especially vulnerable. Wallpaper – They’re after the paste! Food – Especially pantry items like flour, oats, and cereal.
Even worse, they breed quickly. A couple of silverfish can turn into a real problem in just a few months.
How to Tell If You Have Silverfish
Besides seeing them dash across the floor, other signs include:
- Yellow stains or small holes on paper or fabric
- Shedded skins—silverfish molt and leave their shells behind
- Droppings—look for tiny black specks in dark, hidden corners
- Wallpaper damage, especially along seams and edges
If you spot any of these signs in damp areas, you’ve got silverfish.
