Generally, this species only has one generation a year. The time it takes to become an adult varies from six months to a year. In addition, an adult black carpet beetle can live for an additional two months. The average adult size is about 2.8 to 5 mm long and they are oval, dark brown to shiny-black in color, and have brown legs. Varied carpet beetle The varied carpet beetle, Anthrenus verbasci, attacks typical household objects. Carpet beetles are normally associated with things such as carpets, wool, furs, and any processed animal or plant food. Their appetite also includes dead insects, spiders, and even nectar and pollen. They are typically found throughout the United States and Canada. Females can lay up to 40 eggs and the number of larval instars is seven or eight. The time it takes to become an adult varies from about eight months to a year. In addition, the adults can live around 2 to 6 weeks. This species varies in shape, size, color, and pattern of scales. On average, the adults are 2 to 3 mm in length and have scales that vary from white, brown, yellow, or even gray-yellow. The hairs of the larvae can cause allergic reactions such as contact dermatitis or blisters in humans who come into contact with the sharp tiny hairs. Khapra beetle On hatching, the larvae of khapra beetle (Trogoderma granarium) are around 1.6 to 1.8 mm long and mostly covered with dense setae, some simple and some barbed. Larvae are yellow-white but the head and body setae are brown. As the larvae further develop, their color changes to a golden or reddish brown and the abdomen portion becomes proportionally shorter. The mature larvae reach a maximum length of 6 mm long and 1.5 mm wide. The khapra beetle is a stored-product pest. Infestations are difficult to control because they crawl into cracks and crevices, remaining for long periods of time. They tend to infest grains and create serious losses to stored products. The adults are covered with setae and are approximately 1.5 to 3 mm long and 1 to 2 mm wide. Male khapra beetles are brown to black with reddish brown markings on the elytra. Females are slightly larger and are lighter in color. The short, 11 segmented antennae has a club of 3 to 5 segments, which fit into a groove on the side of the
