Physical Characteristics

The drugstore beetle – also known as the bread beetle and biscuit beetle – got its name because it infested stored herbs in apothecaries, or early drugstores. Adults are 1/16 to 1/8 inches long and reddish brown-to brown in color. The drugstore beetle looks a lot like the cigarette beetle (or tobacco beetle), except that the drugstore beetle’s elytra, or shell-like wing covers, are grooved lengthwise, whereas the cigarette beetle’s elytra are smooth. Its antennae culminate in a three-segment club, and are not serrated or saw-toothed like a cigarette beetle’s antennae. Drugstore beetle larvae are 1/16 to 1/8 inches long, whitish, C-shaped, with many short hairs, and look virtually indistinguishable from cigarette beetle larvae.


Drugstore Beetle

Drugstore beetles will attack stored food, herbs and spices, along with items containing keratin – hair, horn, leather, and museum specimens. They’re often found in bread, flour, meal, breakfast cereal, and such spices as red pepper; they also will feed on books and manuscripts. Adults can fly, and they’re attracted to light.


Inspect the above-mentioned items for drugstore beetles or other pests, keep your kitchen and other areas clean, store items in Tupperware-type containers or sealed glass jars in a dry place, and rotate products, using your older goods first. Also, be on the lookout for bird nests, which can provide harborage to – and thus be a source of – drugstore beetles.
