Household Casebearer

Natural Habitat

Commonly found inside homes, on walls, and near baseboards, especially in humid or subtropical climates.

Diet & Feeding

Larvae feed on spider webs, wool, hair, and biological detritus found on household surfaces.

Behavior Patterns

The larvae live inside a spindle-shaped silk case covered in sand, dust, and debris; they can poke their head out from either end of the case to crawl.

Risks & Benefits

Potentially harmful to fabrics like silk or wool and can be a nuisance pest, but they pose no direct health risk to humans.
