Silverfish are white to brown-grey or bluish-silver in color. They have a tail with three long bristles on the rear. Silverfish are capable of thriving in most climates, but prefer to dwell in dark, damp areas such as basements, attics, kitchens, bathrooms and homes with woodshake roofs. They are especially attracted to paper and damp clothing. Commonly found in stored boxes in garages and sheds.
Silverfish are known for their destructive feeding habits, oftentimes ruining papers, clothing and wallpaper. Homeowners often transport silverfish indoors unknowingly. When brought inside the home, cardboard boxes and plastic containers recently stored in infested areas can allow the pests to spread. Warm and moist spaces, like basements and crawl spaces, attract silverfish. The pests will enter homes through foundation cracks, torn screens, or gaps around doors. Leaving dirty dishes out in the open will also lure silverfish indoors.
Silverfish often present a mild risk to people and property. They do not transmit disease, but the pests may trigger allergies in some people. Silverfish also eat grains and chew large holes into clothing, upholstery, or paper. In large numbers, they can cause a lot of damage. Ruined items often include stored files, books, and vintage clothes.
