How to Prevent and Get Rid of Silverfish

Wingless, silver and moving across surfaces in a fish-like motion, silverfish are commonly found slithering along baseboards in closets, basements and attics. Even though silverfish do not bite, they can still cause damage to your home.

Things You Will Need

  • Airtight containers
  • Broom
  • Dustpan
  • Duster
  • Dehumidifier
  • Caulking
  • Insecticide containing boric acid or pyrethroids

Wingless, silver and moving across surfaces in a fish-like motion, silverfish are commonly found slithering along baseboards in closets, basements and attics.  Even though silverfish do not bite, they can still cause damage to your home.

Silverfish feed on various items but seem to prefer materials with a high level of carbohydrates and protein.  Fortunately, you can rid your home of silverfish and prevent them from returning.

  1. Store books, newspapers, papers and magazines in airtight containers. Silverfish feed on these items and will damage them beyond repair.
  2. Clean your home regularly. Sweep floors and dust daily. Regular cleaning will drive silverfish out of your home and keep them at bay.
  3. Reduce the amount of humidity and heat in your home. Silverfish prefer hot areas with a high level of humidity. By lowering humidity and heat, you will reduce the chance of a silverfish infestation. Use a dehumidifier to remove the excess moisture from the air and reduce the level of humidity.
  4. Fix leaks -- such as leaky pipes, faucets and drains -- in your home. These leaks help provide favorable conditions for silverfish.
  5. Fill holes and cracks around your home with caulking to prevent silverfish from entering the home.
  6. Apply an insecticide that contains boric acid or pyrethroids around baseboards, shelves, cracks, bookcases, windows closets, basements and attics. Read and follow all directions and warnings printed on the insecticide label.
