Larder Beetle

Coleoptera, Dermestidae


The larder beetle is a very common and widespread household insect pest. The insect's name comes from it's presence in dried, cured meats stored at room temperature prior to refrigeration. Today, larder beetles may be a pest in stored foods and other items of high protein content. Larder beetles outdoors are valuable “recyclers” that play an important role in the breakdown and recycling of animal protein. The larder beetle adult is slightly longer than 1/4th inch. It is roundly oval and dark brown to black with a characteristic light colored band running across the body. This light band contains 6 more or less prominent dark spots. Larder beetle larvae are up to 1/2 inch long. They are tapered in shape and covered with sparse, stiff hair.


Outside both the larvae and adults feed on items such as fur, hair, hides, feathers, and occasionally stored products such as dried fish, pet food and cheese. Adult beetles are sometimes observed outdoors where they have been feeding upon the pollen of flowers. In the house, however, the most likely source is dead insects or other animals (boxelder bugs, attic flies, mice, etc.) that have accumulated inside walls or attics.


This was found outdoors, probably eating dried cat food.
