Natural Habitat

Commonly found in pantries, kitchens, warehouses, and anywhere dried food products are stored. They can infest homes, grocery stores, and food processing facilities.

Diet & Feeding

Broad range of dried plant and animal products, including grains, spices, stored foods (flour, cereals, bread, dog food), dried herbs, tobacco, paper, and even some drugs.

Behavior Patterns

Adult drugstore beetles are good fliers and are attracted to light. Larvae are typically found within infested food sources, where they feed and develop. The lifecycle from egg to adult takes approximately 40-50 days under optimal conditions.

Risks & Benefits

Potential Risk: Significant pantry pest, causing damage and contamination to stored food products. Infested items must often be discarded. They do not bite or sting humans and are not known to transmit diseases. Potential Benefit: None in a human-controlled environment; as decomposers, they play a minor role in natural environments.
