Case-bearing clothes moth (larva)

Indoor environments, particularly in closets, drawers, or areas with stored animal-based textiles

Keratin-rich materials such as wool, silk, fur, feathers, hair, and leather

The larva builds a portable silken case incorporating fibers from its food source. It carries this case as it feeds and eventually pupates inside it.

Risk: Significant pest that can cause extensive damage to clothing, carpets, and upholstery. No direct health risk to humans, but can be an economic nuisance.
