Silverfish
Lepisma saccharinum
- Order & Family
- Order: Zygentoma; Family: Lepismatidae
- Size
- 12–19 mm (0.5–0.75 inches) in length
Natural Habitat
Damp, dark areas such as basements, attics, kitchens, and bathrooms; they prefer environments with 75% to 95% humidity.
Diet & Feeding
General scavengers that consume matter containing polysaccharides, such as starches and dextrin in adhesives. This includes book bindings, carpet, clothing, coffee, dandruff, glue, hair, some paints, paper, photos, plaster, and sugar.
Behavior Patterns
Nocturnal, fast-moving, and avoid light. They undergo hemimetabolous metamorphosis (egg, nymph, adult) and are unique among insects for continuing to molt after reaching adulthood, potentially living up to eight years.
Risks & Benefits
They do not bite humans or spread disease, but they are considered household pests because they can damage books, photographs, and clothing. They also indicate a possible moisture or humidity issue in the home.
