Silverfish feed on fungal molds and organic matter. They will damage natural fabrics, paper and book bindings. Treatment of cracks and voids as well as attic and crawl spaces is necessary to minimize silverfish. This pest, however, is one of the most difficult insects to totally eliminate even for a professional company.

Silverfish live in cracks and voids and are commonly found in larger numbers in attics, basements, and crawl spaces. They are also common outdoors in southern states. Homes with cedar shake roofs seem to experience more serious infestations of silverfish. This may be due to the additional molds that form on this type of shingle. More available food results in more silverfish. Inside, silverfish will be seen occasionally or on a regular basis in kitchens, bathrooms, and other rooms.
