Attagenus

Attagenus is a genus of beetles belonging to the family Dermestidae, commonly known as skin beetles or carpet beetles. These beetles are found worldwide and are notable for their larvae, which are significant pests of stored products, natural fibers, and museum collections.

Description:

Adult Attagenus beetles are typically small, ranging in size from a few millimeters to around 10 millimeters in length. They are generally oval or elongated in shape and are often dark brown or black in color, though some species may exhibit lighter coloration or patterns. The adults are capable of flight and are attracted to light.

The larvae of Attagenus are elongated and covered in bristles. They undergo several molts as they grow, and the shed larval skins can often be found in areas where infestations are present. The larvae are highly destructive due to their feeding habits.

Habitat and Distribution:

Attagenus beetles are found in a wide range of habitats globally. They thrive in both temperate and tropical climates. They are commonly found in homes, warehouses, museums, and other locations where they can access sources of food such as textiles, furs, dried insects, and grains.

Diet and Pest Status:

The primary concern with Attagenus beetles is the feeding habits of their larvae. The larvae are scavengers that feed on a variety of materials containing keratin, such as wool, silk, feathers, hair, and dried animal products. They can cause significant damage to carpets, clothing, upholstery, taxidermied animals, and insect collections. The adults generally feed on pollen and nectar and do not cause the same level of damage as the larvae.

Control and Prevention:

Controlling Attagenus infestations requires a multi-pronged approach, including sanitation, targeted insecticide treatments, and preventive measures.

• Sanitation: Thorough cleaning, including vacuuming carpets, upholstery, and crevices, is essential to remove potential food sources for the larvae.

• Insecticides: Insecticides labeled for carpet beetles can be used to treat infested areas. It's crucial to follow label instructions carefully.

• Prevention: Storing susceptible items in airtight containers or using cedar chests can help prevent infestations. Regular inspection of stored items and prompt treatment of any infestations are also important. Freezing items for a period of time can also kill larvae and eggs.
