Webbing clothes moth (larval case/larva residue)

Found inside homes, particularly in dark, undisturbed areas like closets, drawers, and under furniture.

Larvae feed on natural animal fibers including wool, cashmere, silk, hair, fur, and feathers.

Larvae secrete silk as they feed, often leaving behind web-like trails or tunnels on fabric. They are nocturnal and avoid light; the life cycle can range from 1 month to several years depending on environment.

Risk: They are major household pests that cause significant damage to clothing, blankets, and rugs. Benefit: In nature, they help decompose animal debris containing keratin.
