Carpet Beetle Larva

Natural Habitat

Found indoors in homes, warehouses, and museums, often in carpets, upholstery, closets, or near baseboards where debris accumulates.

Diet & Feeding

Scavengers that feed on natural fibers and animal products including wool, silk, fur, feathers, leather, dead insects, and dried pet food.

Behavior Patterns

Larvae are avoidant of light (negatively phototactic) and prefer dark, secluded areas. They go through multiple molts, leaving behind translucent brown shed skins. They move slowly and can remain in the larval stage for several months depending on food availability.

Risks & Benefits

They are significant household pests that damage clothing, rugs, and furniture. They do not bite humans, but their stiff hairs (setae) can cause 'carpet beetle dermatitis,' an allergic skin reaction or respiratory irritation in sensitive individuals. They provide no significant benefits to the indoor ecosystem.
