Larder Beetle | Dermestes lardarius

Описание: Dermestes lardarius, commonly known as the larder beetle, is a species of beetle in the family Dermestidae, the skin beetles. It is found worldwide. It is a common pest of households and storage facilities in much of the world.

Adult larder beetles overwinter primarily outdoors, although they are capable of finding their way indoors. The spring and fall months are a common time for larder beetles to enter the home or building. They may enter the structure in search of dead insects, like boxelder bugs, that have died in attics or wall voids.

Adult larder beetles and larvae feed on high-protein materials like pet food and organic fibers such as furs, hair, feathers, and silk. Larder beetles will also feed upon dead insect or rodent remains that have accumulated within walls or attics. Larvae are capable of boring a short distance into wood, books, or insulation for protection as they seek a place to pupate.

Indoors, larder beetles are considered a nuisance. However, they have the potential to be economically important pests. Although not very common, larvae are capable of causing structural damage by boring repeatedly to pupate. Even though adults are capable of biting, they are generally not harmful to humans or pets.

Outdoors, larder beetles are beneficial. They play an important role in breaking down and recycling dead animal and organic materials.
