Black Carpet Beetle

Natural Habitat

Found indoors in homes, warehouses, and museums, as well as outdoors in bird and rodent nests.

Diet & Feeding

Larvae scavenge on keratin and chitin found in animal products like wool, silk, feathers, fur, and leather, as well as dried plant materials and stored grains. Adults primarily feed on pollen and nectar.

Behavior Patterns

Larvae are avoidant of light and prefer dark, secluded areas where food sources are plentiful. They undergo a complete metamorphosis from egg to larva, pupa, and finally adult. Adults are attracted to light and are often seen near windows.

Risks & Benefits

This species is a significant household pest that can cause extensive damage to clothing, upholstery, and carpets. They do not bite humans, but larval hairs can cause allergic reactions or dermatitis in some individuals. In the ecosystem, they serve as scavengers by breaking down organic debris.
