Why silverfish come inside

Silverfish need moisture and starchy food. Damp basements and bathrooms, stored paper and cardboard, and dry foods give them everything they need.

Silverfish don't bite or spread disease, but over time they can damage books, papers, photos, wallpaper, clothing and dry food.
