Silverfish are small, wingless insects with a silvery metallic appearance and fish-like movements. Often called “bristletails,” they are known for the three long, bristle-like appendages at the rear of their bodies. These pests are notorious for infesting and damaging materials such as wallpaper, books, envelopes, and clothing. They feed on paper items, glue, fabric, and food staples like flour and rolled oats, causing significant harm over time. Silverfish thrive in humid environments and are typically found in dark, damp areas like basements and bathrooms.
