Natural Habitat

Moist, humid, and dark areas such as basements, attics, kitchens, bathrooms, and laundry rooms.

Diet & Feeding

Consumes starchy substances and polysaccharides found in book bindings, carpet, clothing, glue, paper, photos, plaster, and sugar.

Behavior Patterns

Nocturnal and extremely fast-moving pests. They undergo ametabolous metamorphosis (lacking a pupal stage) and can live for several years. They avoid light and are often found when items are moved or at night.

Risks & Benefits

They do not bite or transmit diseases to humans but are considered household pests because they can damage books, wallpaper, and textiles. They are a food source for other predatory arthropods like spiders and centipedes.
