Household Casebearer (Case-bearing Clothes Moth larva)

Commonly found indoors on walls, under furniture, or in closets, particularly in warm, humid climates.

The larvae feed on spider webs, wool, feathers, hair, and dust particles containing protein-rich organic debris.

The larva builds a flattened, spindle-shaped silken case covered in sand, dust, and fibers. It can stick its head out of either end to move and feed, and eventually pupates inside the same case.

They are considered minor household pests because they can damage natural fiber fabrics like wool or silk, but they pose no health risk to humans or pets.
