Drugstore Beetles in Coastal Southeastern North Carolina
Drugstore beetles are small reddish-brown beetles that infest stored foods, spices, dried herbs, pet food, and even books and dried flowers. They’re one of the most omnivorous stored product pests, eating things other pantry beetles avoid. Once established in a pantry, they spread between food items quickly.
How to Identify Drugstore Beetles
- Size: 1/8 inch (small)
- Color: Uniform reddish-brown
- Shape: Cylindrical body, hooded head
- Wings: Adults can fly short distances
- Behavior: Active in pantries and storage areas
The smooth cylindrical shape and uniform reddish-brown color distinguish them from cigarette beetles, which have a humped back and pubescent (fuzzy) appearance.
What They Infest
Drugstore beetles eat an unusually wide variety of items:
- Flour, cereal, pasta, rice
- Dried herbs, spices, and tea
- Pet food and bird seed
- Dried fruits and nuts
- Chocolate and candy
- Potpourri and dried flowers
- Leather and leather goods
- Books, especially old books with starch-based bindings
- Dried plant specimens and herbarium collections
Their broad diet makes them difficult to eliminate by simply discarding the obvious infested item, because they’re often in multiple locations.
