Plaster Bagworm

Natural Habitat

Found inside homes, particularly in high-humidity environments like bathrooms or under furniture on walls.

Diet & Feeding

Larvae feed on spider webs, wool, human hair, and silk fibers.

Behavior Patterns

The larva constructs a protective spindle-shaped case from silk and environmental debris, which it carries while crawling in a manner similar to a slug. It can emerge from either end of the case.

Risks & Benefits

They do not bite or sting humans. They are considered household pests as their feeding can damage natural fiber fabrics and carpets.
