Household Casebearer

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

Larvae feed on spider webs, wool, hair, silk, and organic debris

Larvae live inside a flattened, spindle-shaped case made of silk and covered with sand or dust. They can turn around inside the case to protrude from either end.

Considered a household pest that can damage natural fiber fabrics and silk; otherwise harmless to humans.
