The Drug Store Beetle has a large shield that protects its head, and a small body, usually less than ¼ inch in total length. It infests dried food products, and is often incorrectly referred to as a “weevil.” The larvae may also burrow into paper products, especially books. Occasionally they are found in upholstery.

The Drug Store Beetle is considered a pantry pest, but can also spread human tapeworms. They are an intermediate host, and contaminated corn meal and flour, which is undercooked, can then spread the tapeworms to humans.
