Natural Habitat

Indoor environments, particularly in dark, undisturbed areas like closets, under furniture, or storage bins containing animal-based textiles.

Diet & Feeding

Keratin-rich materials including wool, silk, fur, feathers, hair, leather, and occasionally carpets or upholstery fibers.

Behavior Patterns

The larva spins a protective silken tube or 'case' that it drags along as it feeds, incorporating fibers from the material it is eating into the case. They typically avoid light and remain hidden during the larval stage.

Risks & Benefits

Significant household pest; larvae cause permanent damage to clothing, rugs, and heirloom textiles by chewing holes. They are not harmful to human health but can cause substantial economic and sentimental loss.
