Drugstore Beetle (or Cigarette Beetle)

Natural Habitat

Found worldwide, primarily in indoor environments such as pantries, warehouses, kitchens, and libraries.

Diet & Feeding

A wide variety of dried plant and animal products, including flour, cereal, dry pet food, spices, dried books (the glue and paper), and even prescription drugs.

Behavior Patterns

The larvae do most of the feeding damage by boring into items. Adults are proficient fliers, are attracted to light, and typically live for several weeks without feeding once they mature.

Risks & Benefits

They are major pests to stored food, botanical museum specimens, and library books. They do not bite humans or pets, but they can contaminate food sources with waste and larvae fragments.
