Likely clothes moth larva

Dark, undisturbed indoor areas such as closets, carpets, and upholstered furniture.

Larvae feed on keratin-containing materials, including wool, fur, feathers, and lint; adults do not feed on fabrics.

Larvae may leave small silken cases or move away from feeding sites to pupate. The photo is too unclear for a confident species-level identification.

Larvae can damage natural-fiber clothing and furnishings; they are not harmful to people or pets.
