Carpet Beetle (specifically a Case-bearing Clothes Moth larva casing or Carpet Beetle debris)

Found indoors, typically in dark, undisturbed areas such as closets, under carpets, in air ducts, or around baseboards where natural fibers accumulate.

Larvae feed on keratin-rich materials, including wool, silk, fur, feathers, hair, lint, and sometimes stored food products.

The larvae of the Case-bearing Clothes Moth carry a silken case around with them, which they camouflaged with fibers from their environment. Carpet beetles hide in cracks and crevices. They avoid light.

Risks: Major textile pests; larvae can cause significant damage to clothing, carpets, upholstery, and taxidermy. They do not bite or sting humans, though some people may have allergic reactions to larval hairs. Benefits: In nature, they act as scavengers/decomposers of animal matter.
