Case-bearing clothes moth (larva)

Indoor environments, particularly in closets, drawers, or areas with low traffic where natural fabrics are stored.

Larvae feed on keratin-containing animal products such as wool, fur, feathers, hair, felt, and leather.

The larva constructs a protective silk case covered with fibers from its food source, which it carries around as it moves. They are photophobic (light-avoiding) and prefer dark, undisturbed locations.

They are a significant domestic pest that can cause extensive damage to clothing, upholstery, and carpets. They do not pose a direct health risk to humans but can be economically destructive.
