Although silverfish are tiny, they have surprisingly broad appetites. They feed on materials rich in starches, carbohydrates, proteins, and certain natural fibers.
Common food sources include:
- Paper and cardboard
- Wallpaper paste
- Book bindings
- Glue and adhesives
- Dry foods such as flour, cereal, rice, and pasta
- Pet food
- Cotton, linen, and silk fabrics
- Dead skin cells and hair
- Mold and mildew
Because many of these materials are common in modern homes, silverfish often have no difficulty finding food.
3. Dark and Undisturbed Areas
Silverfish prefer hidden spaces where they are unlikely to be disturbed. Cracks in walls, spaces behind furniture, storage boxes, closets, and areas beneath sinks provide ideal shelter.
They are primarily nocturnal, meaning they become most active at night.
Common Places Where Silverfish Hide
Finding one silverfish often means others may be hiding nearby. Knowing where to look can help identify the source of the problem.
Bathrooms
Bathrooms are among the most common silverfish habitats because of constant moisture from showers, sinks, and tubs.
Check:
- Behind toilets
- Under sinks
- Around plumbing fixtures
- Behind baseboards
- Inside cabinets
Kitchens and Pantries
Silverfish are attracted to stored food products and cardboard packaging.
