Natural Habitat

Found worldwide in pantries, kitchens, and warehouses where dried plant material or stored products are kept.

Diet & Feeding

Polyphagous; they feed on dried foods like bread, flour, cereal, and spices, as well as non-food items like leather, books, and pharmaceuticals.

Behavior Patterns

They are capable of flight and are often attracted to light. Females lay eggs directly on food sources, and larvae tunnel through the material as they feed.

Risks & Benefits

No direct health risk to humans as they do not bite or sting; however, they are a significant economic pest that causes food spoilage and can damage historical artifacts like old books.
