General Info
  • Silverfish are fast runners and feed on almost everything
  • They are wingless so they cannot fly
Where They Hide
  • Silverfish live in damp, cool places such as basements and bathrooms
  • They require high-humidity environments
  • They may also be found in bookcases or closet shelves and behind baseboards, windows, or doorframes
What They Want From You
  • They can eat stored food like cereals, but more often they just scavenge small crumbs
  • They also have been known to eat paper that has glue/paste on it, including book bindings and the stains in fabrics
  • They contaminate the food they chew on and stain objects they hide in
Why They’re A Problem
  • Silverfish can stain the objects they hide in like books, cardboard, wall papering, or stored clothing
  • Valuable items like paintings, old books, and documents may also be stained or damaged
