A fast-moving silvery insect in a bathroom or bookcase may be a silverfish. A single sighting does not automatically call for pesticides. Begin with nonchemical prevention recommended by Penn State Extension.

1. Note where you see activity, especially in damp, dark bathrooms, basements, bookshelves and under sinks.
2. Inspect and repair leaking plumbing or condensation; improve ventilation or use a dehumidifier where appropriate.
3. Remove accumulated cardboard, newspapers and paper packaging; keep stored belongings dry.
4. Keep flour, cereals and pet food in tightly sealed containers and vacuum dust from corners and gaps.
5. Seal suitable cracks at baseboards and use monitoring sticky traps away from children and pets.
6. If the problem persists or books and wallpaper are damaged, confirm the insect and consult a pest professional. Never mix pesticide products or spray indiscriminately.
