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, hiring a professional who can create a customized approach is recommended. Traps and insecticides 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. Most do-it-yourself remedies prove ineffective over time, with brief periods of relief followed by another infestation. There are a variety of silverfish traps on the market. However, these traps target individual insects and cannot prevent entire silverfish populations.
Silverfish infestations require professional treatment. Your local pest control expert will be able to assess the situation within your home and determine the most effective methods of extermination for your specific problem. At the first sign of a silverfish infestation, contact your local pest control professional.
White to brown-grey or bluish-silver in color, silverfish are teardrop-shaped insects that measure up to12-19 mm in length. Three long bristles on rear. Grow from egg to adult without visible change in appearance.
