See this bug in the Encyclopedia

Natural Habitat

Commonly found indoors in dark, undisturbed areas like closets, pantries, and under furniture where natural fibers are present.

Diet & Feeding

Larvae feed on keratins found in natural animal fibers such as wool, silk, fur, feathers, and lint, as well as some stored dried foods.

Behavior Patterns

The larva spins a silken case around itself, incorporating bits of fiber from its food source. It carries this case with it as it moves and feeds, never leaving it. It pupates inside this same case.

Risks & Benefits

Significant risk to household property as they damage clothing, carpets, and upholstery. No direct health risks to humans (they do not bite or sting), but they are considered a major domestic pest.
