What do silverfish look like?

Silverfish are a wingless, nuisance pest, they are not a fish at all, but are named “silverfish” because of the silvery-gray scales that cover their body and the fast fish-like manner that they move in.

Adults grow to be about ¾ of an inch in length and their bodies are brown in color. Silverfish have a tear-drop shaped body (think carrot), a distinctive long pair of antennae and a super long bristle-like appendage that comes off the back of their body.

Are silverfish dangerous?

Silverfish are not a dangerous pest to people or pets, they don’t bite or sting and aren’t known to cause any health issues. Silverfish are considered to be general feeders, this means they will feed on almost anything, but they do prefer items that are high in starches, sugar, and protein.

Their feeding habits mean that they can contaminate food and damage items inside of a home like wallpaper, pictures, books, clothing, furniture and carpets.

Why do I have a silverfish problem?

Silverfish seek dark, high humidity environments and may enter homes through cracks in the foundation and/or crawlspaces and through spaces found underneath of doors while foraging for food and suitable shelter. The most common way that silverfish are introduced into a home is by bringing in boxes, piles of papers, or packages that are already infested with these nuisance pests.

Inside they can be found living in the basement, attic, crawl space, and bathrooms- silverfish also feed on cellulose which is found in shaving foams, shampoos and other personal products.
