Household Casebearer

Found inside houses, particularly in areas with high humidity, on walls and in corners.

Larvae feed on spider webs, wool, and natural fibers like hair or fur.

The larva lives inside a portable, flattened, silk-lined case covered in sand or dust. It is often seen crawling slowly up walls.

Generally harmless to humans but can occasionally damage silk or wool fabrics. They help clear away spider webs.
