Household casebearer

Typically found inside houses, on walls, or under furniture in warm, humid climates.

Larvae feed on spider webs and natural fibers like wool, silk, and human hair/dander.

The larva constructs a protective spindle-shaped case from silk, dust, and sand; it can poke its head out from either end to move or feed.

They are considered a minor household pest because they can damage clothing or fabrics made of natural fibers; they pose no physical risk to humans.
