Household Casebearer (often nicknamed Plaster Bagworm)

Typically found indoors in warm, humid climates; commonly seen climbing plaster walls, in closets, on carpets, or underneath furniture.

Larvae are detritivores that feed on old spider webs, dead insects, shed human hair, pet fur, wool, and lint.

The larva constructs a protective, flattened, spindle-shaped case using silk and debris (sand, paint fragments, dust) from its environment. It drags this 'house' along as it travels and can extend its head from either opening to feed.

Primarily a nuisance pest. They do not bite or sting humans or pets. However, they can cause minor damage to fabrics, rugs, and wool clothing, similar to clothes moths.
