Drugstore Beetle

Natural Habitat

Found worldwide in human structures, particularly in pantries, kitchens, pharmacies, and locations where dry organic matter is stored.

Diet & Feeding

A generalist feeder on a wide variety of dried plant and animal products, including flour, cereal, dry pet food, spices, leather, wool, and even toxic substances like prescription drugs.

Behavior Patterns

Adults are capable of flight and are often attracted to light; they do not eat but focus on reproduction. The destructive stage is the larva, which tunnels through food sources during development. They have a symbiotic relationship with yeast that allows them to digest various low-nutrient materials.

Risks & Benefits

Primarily an economic and household pest. They damage food supplies and can bore through packaging material. They are not harmful to human or pet health in terms of bites or disease, but they contaminate food and can cause significant losses in libraries or museum collections by eating book bindings and specimens.
