Household Casebearer (often the larva of the Plaster Bagworm or similar clothes moth)

Found indoors in homes, particularly in humid climates; often seen on walls, baseboards, carpets, and in closets.

Feeds on natural fibers like wool and silk, spider webs, dead insects, lint, and sometimes dried food products.

The larva constructs a flattened, pumpkin-seed-shaped protective case out of silk and debris (sand, dust, fibers) which it carries around. It emerges from either end to feed or move.

Risks: Can be a household pest that damages woolen clothing, rugs, and upholstery. Benefits: None significant to humans, though they do help decompose minor organic debris.
