Household Casebearer

Indoor environments, particularly on walls and under furniture in humid climates

Natural fibers including wool, fur, hair, and silk, as well as spider webs and dead insects

The larva constructs a protective silk-lined case covered in dust and debris; it can peek out from either end of the case to feed or move

Considered a household pest as it can damage clothing and carpets made of natural fibers; no direct risk to human health
