Likely carpet beetle larva or shed skin

Indoor fabrics, carpets, upholstered furniture, closets, and areas containing lint or pet hair; adults may occur near windows and flowers.

Larvae consume keratin-rich materials such as wool, fur, feathers, hair, and dead insects. Adults generally feed on pollen and nectar.

Larvae hide in dark, undisturbed places and molt repeatedly, leaving bristly shed skins; adults are winged and often attracted to light. They develop slowly indoors and may damage stored textiles.

Larvae can damage clothing, carpets, and taxidermy materials; their hairs may cause mild skin or respiratory irritation. They are harmless to people and contribute to decomposition outdoors.
