Natural Habitat

Warm, high-humidity environments indoors; often found in books, papers, wallpapers, stored food, and sometimes on damp fabrics or furniture.

Diet & Feeding

Feeds on microscopic mold, fungi, starch, glue (book bindings), and grain products.

Behavior Patterns

They do not fly but run in a jerky, halting manner. They thrive in damp conditions and are often associated with mold growth due to humidity.

Risks & Benefits

Generally considered a nuisance pest rather than a direct threat; they do not bite humans or animals and do not transmit disease, though large populations can contaminate food and may trigger allergies in sensitized individuals.
