Plaster Bagworm

Humid environments, often found on walls inside homes, garages, and under floorboards where moisture is present.

Larvae feed on spiderwebs, wool, human hair, fur, and various natural fibers/debris found in household dust.

Larvae construct a protective silk case covered in sand, dust, and fiber particles; they are active foragers that can poke their heads out of either end of the case to crawl.

Generally considered a harmless household pest; they do not bite humans but can cause minor damage to wool fabrics or decorative items made of natural fibers.
