Household Casebearer (Plaster Bagworm)

Commonly found inside homes, particularly on walls in humid subtropical environments

Larvae feed on spider webs, wool, hair, and natural fibers

The larva constructs a protective silk case covered with sand, dust, and debris. It can turn around inside the case to feed from either end.

Generally harmless to humans but can be a minor pest of household fabrics and natural fibers; they help clean up old spider webs.
