Household Casebearer

Indoor environments, particularly in humid climates, often found on walls or under furniture.

Larvae feed on spider webs, wool, hair, and organic debris found in household dust.

The larva constructs a silken flat, pumpkin-seed shaped case covered in dust and sand. It drags this case while moving and can retract inside for protection or pupation.

Generally harmless to humans. They are considered minor household pests as they may occasionally damage woolen fabrics or natural fiber clothing.
