The tear-drop-shaped Silverfish is brown-to-blue gray in color. They can survive in almost any environment, but prefer cooler and damper environments, which makes them a considerable pest problem in the Pacific Northwest. 1/2” – 1” in length, Silverfish can cause damage in homes with their destructive feeding habits and also pose a health threat by getting into our food and home supplies.

Silverfish Detection and Prevention

Silverfish are nocturnal and fast moving, which can make them hard to spot.  The most common place to spot them is around the drains in bathtubs and in or around sink cabinets.  You may also detect a Silverfish problem by their destructive feeding patterns (on linens, wallpapers, silks and paper goods) and their pepper-like fecal material.

Being elusive and rapid breeding means that a Silverfish infestation can often go undetected until it is severe.  When this happens, a trained professional is usually required to remove the current problem and more importantly, prevent its re-occurrence.

Stringent housekeeping practice is the best deterrent for Silverfish as well as keeping the exterior and interior of your structure well sealed.

Silverfish Behavior

Silverfish seek their homes in dark, damp places, which draws them to basements, bathrooms, kitchens, attics, and garages.

Feeding primarily on starches, sugars, and cellulose, Silverfish will find food sources in everything from our food to our home goods, including shampoos, soaps, and even glue.

In addition to the health risks they can cause, Silverfish can be destructive to wallpapers, linens, papers, and garments.  They are also rapid breeders, with some species laying up to 20 eggs a day.
