Carpet Beetle

Natural Habitat

Indoor environments, particularly in carpets, upholstery, closets, and baseboards; outdoor environments in bird nests or on flowers.

Diet & Feeding

Larvae feed on natural fibers such as wool, silk, fur, and feathers, as well as stored pantry goods like grains and dry pet food. Adults primarily feed on pollen and nectar.

Behavior Patterns

The beetles undergo complete metamorphosis. Adults are often seen crawling on walls toward light sources or windows. They are most active in spring and summer.
