Carpet Beetle (Larva)

Natural Habitat

Typically found indoors in dark, undisturbed areas like under furniture, in closets, drawer cracks, and carpets. In nature, they live in bird nests and animal dens.

Diet & Feeding

The larvae (pictured) feed on keratin-rich natural fibers such as wool, silk, fur, feathers, hair, leather, and dead insects. They do not eat synthetic fabrics unless soiled with food or sweat.

Behavior Patterns

Larvae are photophobic (they avoid light) and move slowly. They undergo complete metamorphosis, living as larvae for several months to a year, molting multiple times and leaving behind light brown, papery shed skins.

Risks & Benefits

Risks: They are a major household pest that causes significant damage to clothing, carpets, tapestries, and taxidermy. The bristles on the larvae can cause an allergic skin reaction called 'carpet beetle dermatitis' in some people. Benefits: In nature, they are scavengers (decomposers) that help break down dead animal matter.
