Carpet Beetle

Natural Habitat

Indoors, especially in areas with organic fibers like carpets, clothing, upholstered furniture, and natural insulation. Also found in nests of birds and other animals outdoors.

Diet & Feeding

Larvae feed on a wide variety of animal-based materials, including wool, silk, fur, feathers, leather, dried meat, dead insects, and pet dander. Adults feed on pollen and nectar outdoors.

Behavior Patterns

Adult carpet beetles are often attracted to light and may be found near windows. However, the larvae cause damage by feeding in dark, undisturbed areas. They undergo complete metamorphosis; eggs are laid on preferred food sources, larvae hatch and feed, pupate, and then emerge as adults. Larval stages can last for several months to a year.

Risks & Benefits

Risks: Can cause significant damage to household items made of natural fibers, including clothing, carpets, and museum specimens. Some individuals may experience allergic reactions to larval hairs. Benefits: Outside of human dwellings, they play a role in decomposition by consuming animal remains and shed organic material. Adults can also act as pollinators.
