Natural Habitat

Indoor environments, specifically dark, undisturbed areas like closets, drawers, and under furniture where natural fibers are stored.

Diet & Feeding

Keratin-rich materials including wool, silk, feathers, fur, and hair. They occasionally feed on synthetic fibers if blended with natural ones or stained with food/sweat.

Behavior Patterns

The larva spins a portable silken case incorporating debris and fibers from its food source. It carries this protective case as it crawls and eats, eventually pupating inside it. Adults do not feed and are primarily active at night.

Risks & Benefits

They are a significant domestic pest, causing irreversible damage to clothing, carpets, and upholstery. They pose no direct health risk to humans but can be economically damaging.
