Silverfish

Natural Habitat

Typically found in dark, moist, and humid environments within homes, such as bathrooms, basements, attics, and kitchens. They often hide in cracks, crevices, or under objects during the day.

Diet & Feeding

They feed on carbohydrates and starches. Their diet includes paper, glue (in book bindings), wallpaper paste, photos, fabric (cotton, linen, silk), sugar, dead insects, and dandruff.

Behavior Patterns

Silverfish are nocturnal and move very quickly with a wiggling motion that resembles a swimming fish (hence the name). They are long-lived insects (up to 3 years) and can survive for long periods without food.

Risks & Benefits

They do not bite, sting, or transmit diseases to humans. However, they are generally considered household pests because their feeding habits can damage books, wallpaper, clothing, and stored food items. Their presence often indicates high humidity levels.
