Silverfish are small insects with silvery scales that rub off easily. They also have 3 long antennae-like tails. They're active at night, and like starchy materials, such as paper. They can live for up to 4 years.
They Come Out at Night and Eat Paper
You flip on the light in your bathroom, only to see little gray bugs running for cover. If they have long antennae-like tails and are covered with silvery scales, you're looking at silverfish. They like damp places and live on the starch in paper, book bindings, and well-pressed shirts. The outdoor species, called bristletails, eat molds, lichen, and dead insects. Here are some simple steps you can take to control them.
Cut Back on Your Reading Material
Magazines, newspapers, and books are favorite feeding grounds for silverfish. While you don't want to toss every book in the house, the extra magazines and newspapers lying around might be prime silverfish food. Recycle them, along with paper bags, at your local recycling facility. Protect your important papers by storing them in sealed plastic containers or bags.
Seal Holes and Cracks
Holes around pipes are good hiding places for silverfish. Seal them up, as well as any other holes and cracks in your siding, screens, or near windows.
