Silverfish don’t directly eat clothing--they’re more interested in what’s in the fabric than the fabric itself. Nevertheless, they can do real damage to what’s in your closet.
A silverfish, sometimes called a bristletail, is a flat, skinny, wingless insect with long antennae and three long tails out its backside.
Silverfish are long-lived insects and slow breeders, but a female can have up to 100 offspring before she dies. Eggs hatch in as little as three weeks, and the juveniles mature by six weeks.
Silverfish live in wet places and can often be found in bathtubs, book and closet shelves, as well as window frames.
Silverfish eat the starch in clothing, especially in cotton, linen, rayon or wool. The damage usually appears as a stain.
Store clothing and books in dry places, and use mothballs or pest strips in closets. Keep carpets and walls clean, and reduce your home’s humidity.
If you have a serious infestation, there are insecticides made specifically for silverfish (see Resources).
