Carpet beetles are typically small black beetles that are approximately 1/8 of an inch long. The adult beetles and larvae both tend to feed in dark, undisturbed areas. Carpet beetles feed on animal fibers, such as wool, silk, fur, feathers, and leather. Their feeding habits make carpet beetles a serious threat to your home, as they can damage clothing, bedding, and carpet. Carpet beetle infestations spread quickly and can cause major damage to your home.
