Household Casebearer

Indoors in humid climates, often found on walls, under furniture, and in corners where dust and silk accumulate.

Larvae scavenge on natural fibers including wool, fur, hair, and silk, as well as spider webs and dead insects.

The larva constructs a protective, spindle-shaped case from silk and environmental debris (dust, sand, fibers). It can turn around inside the case to protrude from either end to feed or move.

Generally harmless to humans but considered a household pest because it can damage clothing, upholstery, and carpets made from natural fibers.
