Household Casebearer / Plaster Bagworm

Commonly found inside homes, on walls under spider webs, or in closets and bathrooms

Larvae feed on spider webs, wool, human hair, felt, and other natural fibers

The larva constructs a protective silk case covered with sand, soil, or lint. It moves along surfaces by extending its head and legs from the front of the flat, melon-seed shaped case.

Presents a minor risk as a household pest that can damage textiles and natural fibers; however, they are not harmful to humans or pets.
