Household Casebearer

Found inside homes, particularly in humid corners, under furniture, or on walls and baseboards.

Larvae feed on spider webs, wool, hair, and organic detritus such as dead insects.

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

Generally considered a minor indoor pest; they can occasionally damage natural fabrics like wool or silk, but they do not pose a direct health risk to humans.
