What Are Silverfish?


Silverfish are common household pests that can be a nuisance. They’re attracted to damp and dark places. So they are a common problem in bathrooms, attics, and basements. They usually come out to feed at night.

Silverfish are small and slender and have a silver/grey body with a blue sheen. They have an elongated oval shape with scales. They’re harmless to humans, but they can cause damage to fabrics, papers, books, and other items in your home.


Are Silverfish Dangerous?


No, silverfish are not dangerous to humans. You won’t have to worry about silverfish biting you or spreading disease to humans. However, they can cause tons of damage to the things inside your house.


What Do Silverfish Feed On?


Silverfish are scavengers that feed on a variety of things, including:

  • Starches – such as wallpaper, book bindings, and cereal
  • Animal protein – such as dead insects, hair, and nail clippings
  • Dyes and inks – found in fabrics, clothing, and wallpaper
  • Mold and mildew – often found in damp areas such as basements and bathrooms
  • Sugars – found in food and drink spills
  • Molds – found in damp areas such as basements and bathrooms
  • Cellulose-based materials – such as paper, cardboard, and insulation

Silverfish can also go for long periods without food. It is one of the reasons why they’re so difficult to get rid of. They can survive in small cracks and crevices, making it hard to reach them with traditional pest control methods.
