Carpet beetle (likely a varied carpet beetle)

Homes, especially closets, carpets, upholstered furniture, and places where lint, hair, or dead insects collect.

Adults feed mainly on pollen and nectar; larvae eat animal-based materials such as wool, feathers, fur, and dead insects.

The pictured beetle is very small and mottled, consistent with a carpet beetle, though the photo is not detailed enough for certain identification. Larvae develop indoors and may leave shed skins; adults often appear near windows.

Harmless to people and pets, but larvae can damage natural-fiber textiles. Adults help pollinate flowers outdoors.
