Ranging from 12 to 19 mm in size, silverfish are household pests that are attracted to dark, damp areas. They range in colors including white, brown-grey, and bluish-silver. Silverfish are wingless with a flat appearance and 3 thread-like tails. Their size and shape allow them to hide in small spaces.
They feed on starch and sugar and find a lot of these options in your home. You can find them eating paste from book bindings, photos, clothing, bedding, curtains, old papers, wallpaper paste, shampoo, dead insects, pasta, flour, cereal, and other common starches. Because of this they are typically found in kitchens and pantries.
Beyond the kitchen, they can be found in bathrooms, basements, attics, and laundry rooms, which provide dark, damp spaces. They usually find their way indoors when the weather begins to get warmer and drier or when there is excessive rainfall.
Their jaws aren’t strong enough to pierce human skin, but they are fast and can usually escape predators fairly quickly. They will cause damage to your home by chewing fabrics, contaminating food they are eating, and triggering allergies.
Common signs of silverfish include:
- Holes, notches, edges on surface they eat
- Yellow stains or discarded scales
- Feces in the form of tiny black pellets
- Cleaning out closets and cabinets and dusting bookshelves
- Storing food in airtight containers
- Removing piles of wet leaves from your yard
- Using a dehumidifier in damp areas like basements and crawlspaces
- Keeping the perimeter of your home clean and dry
- Sealing the exterior of your home
