Household Casebearer (often confused with Plaster Bagworm)

Typically found indoors in humid climates; common on stucco walls, under furniture, in garages, and often seen hanging from cobwebs or crawling on carpets and woolens.

Detritivores that feed on organic debris including hair, lint, spider webs, dead insects, woolen fibers, and fur.

The larva lives inside and drags around a flattened, pumpkin-seed-shaped protective case made of silk and debris. The case has openings at both ends so the larva can turn around inside to feed from either end. They eventually pupate inside this case.

Risks: Generally considered a minor household pest; they do not bite or sting humans but can damage fabrics like wool, silk, or fur if left unchecked in closets. Benefits: They can act as minor janitors by cleaning up dead insects and spider webs.
