Attagenus

Attagenus is a genus of beetles belonging to the family Dermestidae, commonly known as carpet beetles. These small, oval-shaped beetles are often found in and around human dwellings, where their larvae feed on a variety of organic materials, including fabrics, carpets, stored food products, and animal specimens. The adults are typically dark brown or black and measure between 2 to 5 millimeters in length. They are often attracted to light and can be found on windowsills or walls.

The life cycle of Attagenus beetles involves egg, larval, pupal, and adult stages. The larvae are hairy and worm-like, and it is during this stage that they cause damage by consuming keratin and other proteins found in natural fibers. Depending on environmental conditions and food availability, the larval stage can last for several months to over a year. Adult beetles, in contrast, feed on pollen and nectar and have a much shorter lifespan, typically only a few weeks.

Several species within the Attagenus genus are considered pests. Attagenus pellio, the two-spotted carpet beetle, is a common example, characterized by two distinct pale spots on its elytra. Attagenus unicolor, the black carpet beetle, is another widely distributed species, notable for its uniformly black appearance. Control of Attagenus infestations usually involves thorough cleaning to remove food sources and larval habitats, along with targeted insecticide treatments if necessary. Identification of the specific species can aid in effective management strategies.
