Household Casebearer

Typically found inside buildings, especially on walls of houses in warm, humid climates.

Larvae feed on natural fibers such as wool and silk, as well as spider webs and organic debris.

The larva constructs a protective silk case covered in sand, dust, and debris. It is open at both ends, allowing the larva to turn around inside and emerge from either side to travel and feed.

Generally harmless to humans but can be considered a household pest as it may damage clothing, rugs, or fabrics made of natural fibers.
