Silverfish

Natural Habitat

Damp, dark, and cool environments like basements, bathrooms, kitchens, and attics; often found near paper and starch sources.

Diet & Feeding

Strictly herbivorous/detritivorous; they feed on carbohydrates and sugars, including book bindings, wallpaper paste, cereal, and clothing containing starch.

Behavior Patterns

Nocturnal and extremely fast runners; they avoid light and can live for several years. They undergo ametabolous metamorphosis (gradual development without distinct pupal stages).

Risks & Benefits

They do not bite humans or spread disease, but they are considered household pests because they can damage property such as books, photos, and clothing. They play a minor role in debris decomposition in nature.
