Household Casebearer

Typically found inside houses, particularly on walls in humid environments, as well as under furniture and in closets.

Larvae feed on spider webs, wool, hair, and household fibers.

The larva constructs a protective silk case flattened like a pumpkin seed, covered with sand or dust. It can move by poking its head out from either end of the case.

They are considered minor household pests because they can damage silks and wool fabrics, though their presence mostly indicates high humidity or an accumulation of dust and spider webs.
