Household Casebearer (often confused with Clothes Moth Larva)

Typically found indoors in warm, humid climates; often seen on stucco walls, under furniture, in closets, or around spider webs in corners.

Detritivores feeding on old spider webs, wool, hair, lint, dead insects, and natural fibers.

The larva constructs a flattened, pumpkin-seed-shaped protective case out of silk and debris (sand, soil, fibers) which it drags around as it moves. It can turn around inside the case to feed from either end.

Generally considered a minor pest. While they can damage wool or biological fibers, they usually feed on general house dust and cobwebs. They do not bite or sting humans.
