Natural Habitat
Common indoors in dark, undisturbed areas such as closets, drawers, under furniture, in carpets, baseboards, and storage boxes containing natural fibers.
Diet & Feeding
The larvae feed on keratin-rich natural fibers including wool, silk, fur, feathers, hair, dead insects, and pet dander. Adults feed on pollen and nectar.
Behavior Patterns
Larvae prefer dark, secluded places and molt multiple times as they grow, leaving behind light brown, translucent shells or 'skins' (like the one pictured). They are photophobic (avoid light).
Risks & Benefits
