Household Casebearer

Indoor environments, particularly in humid climates. Often found on walls, under furniture, or in closets.

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

The larva builds a flattened, spindle-shaped case from silk and debris that it carries for protection. It can move by protruding its head and legs from either end of the case.

Generally considered a minor household pest because they can damage silk or wool clothing and fabrics, but they do not pose any health risk to humans.
