The beetle family (Dermestidae) consists of carpet beetles, which feed on animal and plant matter and may, therefore feed on wool clothes or stored food. The most common beetles in Michigan are described. The larder beetle requires animal products to reach maturity, and is a common pest in dried dog food. Cleaning and use of an insecticide are recommended for control. The Black Carpet Beetle infests wool rugs, furniture, and grains. Length of life cycle depends on available food and temperature. The Varied Carpet Beetle and the Common Carpet Beetle are similar, and both may infest flour, spices, woolens, silk, and other items of animal origin. Control for carpet beetles starts with prevention measures. The best prevention is good housekeeping. Several classes of insecticide are discussed, with the emphasis on safety measures.
