Dark, damp indoor areas such as bathrooms, basements, wall voids, and storage spaces; also leaf litter outdoors.

Feeds on carbohydrates and starchy materials, including paper, book bindings, wallpaper paste, fabrics, and crumbs; usually scavenges at night.

Fast-running, wingless, and nocturnal, it hides in cracks during daylight. Development is gradual, and adults may live for several years.

Generally harmless to people and does not transmit disease, but it can damage paper, books, wallpaper, and some textiles. It contributes modestly to decomposition outdoors.
