Natural Habitat

Found in damp, high-humidity environments like basements, kitchens, or bathrooms, often hidden behind wallpaper, in stored food, or on old book bindings.

Diet & Feeding

They feed primarily on microscopic fungi, mold, algae, and organic starches such as glue from book bindings and cereal paste.

Behavior Patterns

They are wingless, fast-running insects that thrive in moist conditions. They reproduce quickly in humid environments but will die if humidity drops below 50-60%.

Risks & Benefits

They do not bite humans or pets and do not transmit disease. They are primarily nuisance pests that indicate a humidity problem or the presence of mold, though they can contaminate dry food goods.
