Plaster Bagworm

Commonly found inside homes on walls, under furniture, and in garages or sheds, particularly in humid climates.

Larvae feed on spider webs, wool, human hair, and silk, as well as organic lint and debris.

The larva constructs a silken case covered in sand, dust, and lint for protection. It can move the case by poking its head out of either end. It undergoes metamorphosis inside this case.

Harmless to humans as they do not bite or sting. However, they can be considered a minor nuisance or household pest because they may feed on natural fiber fabrics and leave unsightly cases on walls.
