Natural Habitat

Dwellings, granaries, and warehouses; typically found in pantries or kitchens around stored food products.

Diet & Feeding

Polyphagous; they eat a wide variety of dried plant products including flour, bread, spices (like paprika), pet food, and even medicinal herbs or books.

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 and grow until pupation.

Risks & Benefits

They are serious household and commercial pests that contaminate and destroy food supplies. They pose no direct physical risk (stings or bites) to humans but can cause significant economic loss and waste through food spoilage.
