Adult carpet beetle (likely a black carpet beetle)

Adults occur indoors on carpets, woolens, and near windows; larvae develop in dark places containing animal-based materials.

Adults mainly feed on pollen outdoors; larvae eat wool, fur, feathers, hair, and other animal-derived materials.

The pictured small, oval, dark-brown beetle is consistent with an adult carpet beetle. Larvae—not adults—cause most household damage; adults may wander or fly toward light.

Larvae can damage textiles and shed hairs that may irritate skin. They do not bite or transmit disease; adults can pollinate flowers.
