Case-bearing clothes moth larva (likely)

Dark, undisturbed indoor areas such as closets, carpets, upholstery, and stored textiles; larvae often carry a portable silk-and-fiber case.

Larvae eat keratin-containing materials, including wool, fur, feathers, hair, and occasionally natural-fiber textiles. Adults do not feed on clothing.

Larvae avoid light and crawl while concealed in their case, enlarging it as they grow. They pupate within or near the case; adults are small, weak-flying moths.

They can damage wool, fur, carpets, and other animal-derived fabrics, but do not bite or transmit disease. They contribute modestly to decomposition of keratin-rich debris.
