The Drugstore Beetle has a brown oval shaped body with grooves running down its back. Adults can fly and are attracted to light. Adults may be first noticed near windows or on windowsills. Once a food source is located, females lay up to 75 eggs and the larvae hatch within a few weeks. Larvae transitions take months to complete, during which time the larvae are feeding on the food source.
The larvae of the Drugstore Beetle are small, c-shaped and white. They feed on stored dried foods such as cereals, grains, fruits, vegetables, cookies, spices, and chocolate and have also been found in pharmacies feeding on medicinal herbs and prescription drugs. They also eat the paper and leather bindings on books.
Inspect dry foods and packaging before purchasing and store pet foods away from pantry. Discard infested food and vacuum food storage area thoroughly, especially in cracks and corners. Store dry food goods in airtight containers.
The Drugstore Beetle can be active all year, especially in warm weather and heated buildings.
