Silverfish are nocturnal insects typically 13–30 mm (0.5–1 in) long. Their abdomens taper at the end, giving them a fish-like appearance.
Silverfish are considered household pests, due to their consumption and destruction of property.
They eat a wide variety of foods, including glue, wallpaper paste, book bindings, paper, photographs, starch in clothing, cotton, linen, rayon fabrics, wheat flour, cereals, dried meats, leather and even dead insects.
Silverfish often live in damp, cool places.
