Plaster Bagworm

Typically found in tropical and subtropical regions; often found inside buildings, on walls, or under furniture where dust and debris accumulate.

Feeds on spider webs, fallen hair, lint, and natural fibers like wool and silk.

The larva constructs a protective silk case covered in sand, dust, and debris. It can crawl with its case and move by poking its head out from either end. It eventually pupates inside this case.

Generally considered a minor household pest; they can damage natural fiber clothing and carpets, but they do not pose a direct health risk to humans or pets.
