This insect gets its name from its silvery, metallic appearance and fish-like shape and movements. Silverfish have no wings, but are able to run very fast. They tend to hide their presence from humans which means any damage they have caused could go unnoticed as well.
Silverfish tend to feed on paper items, glue, clothing and food items, such as flour and rolled oats. Silverfish can live up to a year without food, but require a high humidity environment. They move fast and are typically nocturnal.
Silverfish are found throughout the U.S. and are typically seen in moist, humid areas in the home, such as bathrooms, basements, and attics.
While silverfish are mainly a nuisance pest, they can contaminate food and damage paper goods such as wall paper and books.
Consider a dehumidifier for your home, repair leaky pipes and drains and eliminate or repair any moldy or wet wood. Don’t keep old books and magazines in areas where silverfish are usually found like basements, attics and garages. It’s also important to keep food items such as flour and sugar in tight containers.
