Household Casebearer (Case-bearing Clothes Moth larva)

Natural Habitat

Commonly found inside homes, particularly on walls in humid environments, bathrooms, garages, and under furniture.

Diet & Feeding

Larvae feed on spider webs, wool, silk, hair, and other organic debris. They may occasionally damage natural fiber clothing or upholstery.

Behavior Patterns

The larva constructs a protective silk case covered in sand, dust, and lint (resembling a pumpkin seed or husk). It can poke its head out of either end to move or feed. It eventually attaches the case to a vertical surface to pupate.

Risks & Benefits

They are considered minor household pests because they can damage clothes and textiles made of natural fibers. They do not bite or pose directly health risks to humans, but can be an indicator of high humidity or accumulation of dust and cobwebs.
