Drugstore Beetle

Natural Habitat

Commonly found indoors in pantries, warehouses, and storage areas; often infests stored food products, spices, pet food, and sometimes book bindings or pharmaceutical products.

Diet & Feeding

Polyphagous scavengers; they consume a wide variety of dried plant products, including flour, grains, spices (especially red pepper), cereals, pet food, leather, tobacco, and dried museum specimens.

Behavior Patterns

Adults are active fliers and are attracted to light. The larval stage is responsible for the damage, tunneling through stored goods. Their life cycle from egg to adult takes 3 to 7 months depending on temperature and food availability.

Risks & Benefits

Risks: Major pest of stored food products, capable of ruining large quantities of pantry items. They are generally harmless to humans (they do not bite or sting) but can contaminate food with larvae and waste. Benefits: None in a household setting; ecologically, they act as decomposers of dried organic matter.
