Household Casebearer

Commonly found inside residential homes, specifically on walls or in corners, humid environments, and closet spaces.

Larvae feed on spider webs, wool, hair, and organic fibers containing keratin.

The larva constructs a protective silk case covered in sand, dust, and lint; it can turn inside the case to feed from either end.

Potentially harmful to natural fiber clothing, rugs, and upholstery; does not pose a direct health risk to humans but is considered a household pest.
