Household Casebearer

Indoors within households, particularly in warm, humid climates; often found on walls or floors.

Larvae feed on spider webs, wool, hair, and biological debris found in household dust.

The larva builds a flattened, spindle-shaped case from silk and environmental debris (sand, dust, lint) which it drags along as it moves. It can poke its head out from either end of the case.

Generally considered a minor household pest. They do not bite or sting, but their presence can be a nuisance and they may occasionally damage silk or wool garments if food sources are limited.
