Likely a carpet beetle larva (or shed larval skin)

Indoors, especially carpets, closets, and stored natural-fiber materials; larvae hide in dark, undisturbed areas.

Larvae feed on wool, feathers, fur, lint, dead insects, and other animal-derived materials; adults mainly feed on pollen outdoors.

Larvae are slow-moving and often leave bristly shed skins as they molt. Adults may enter homes from outside and lay eggs near food sources.

Do not bite or spread disease, but larvae can damage fabrics and stored items; their hairs may irritate sensitive skin.
