Silverfish are nocturnal and move very quickly. They are secretive, and the severity of an infestation may go unnoticed for long periods of time, allowing for exponential growth. Silverfish reproduce quickly.
Silverfish are known for their destructive feeding habits, oftentimes ruining papers, clothing and wallpaper. They commonly infest dark, damp areas around paper and linen sources. Silverfish infestations can be found in kitchens, laundry rooms, bathrooms, attics and basements.
Silverfish can survive in almost any environment, but they prefer areas with high humidity. Nymphs develop faster in areas that are humid. Therefore, one of the best ways to prevent an infestation is to control humidity. In crawl spaces, open vents and in basements, use baseboards with caulking. Silverfish consume a variety of foods, and stringent housekeeping practices may help prevent an infestation by limiting potential feeding sites.
However, if your home already hosts a silverfish population, Traps sold in stores will only kill individual insects and cannot address an entire infestation. Some people try to use cinnamon to repel silverfish from certain areas, but it does not kill the insects or their eggs.
Addressing a silverfish infestation requires treatment of both adult silverfish and their harborage.
