Household Casebearer

Indoors within houses, storage areas, and garages, often on walls or in corners

Larvae feed on spider webs and natural fibers including wool, silk, and human hair

Larvae construct a protective silk case covered in fragments of sand, dust, and fiber; they can turn around inside the case to feed from either end

They are a household pest that can damage woolens and carpets but are harmless to humans and pets
