• The back of these insects are spotted with gray-yellow,brown,and white scales which form two bands across the top.
• The underside of the body is gray to yellow.
Biology
• Females lay about 40 eggs in a lifetime; eggs hatch in 10 to 20 days.
• Larvae develop in 222-323 days and remain as a pupae for 10 - 13 days.
• One generation per year.
• Adult beetles live 14 - 44 days.
• Complete metamorphosis
Habits
• The larvae feed on a wide variety of foods, including carpets, woolens, skins, furs, stuffed animals, leather bindings on books, feathers, silk, and plant products, (corn, and red pepper).
• The favorite larval food, however, is dried insects or spiders, and, these insects are terrible pests in dried insect collections.
• Adults feed on pollen, are good fliers, and enter homes through open windows.
Control• The initial step in carpet beetle control is the
correct identification of the pest, followed by a thorough inspection by a Pest Management Professional. The PMP will identify and eliminate the sources of the infestation.
• The customer should be questioned about past pest problems, birds, flies and other insects, rodents, etc. and the sites of these infestations closely examined.
• All products containing natural materials should be examined, paying particular attention to stored clothing, carpets, and food products
• Sanitation, including removal and/or treatment of infested material, is the first step in remediating the problem.
Application • The exterior of the structure should be inspected
for plants that attract the adult beetles and should be removed or treated with an appropriately labeled product.
• During warmer months, perimeter foundation treatment with a wettable powder or micro encapsulated formulation reduces the number of beetles entering the structure
• Application of a residual insecticide to cracks and crevices and immediate area around an infestation site with an appropriately labeled product might be necessary
• In cases where the infestation is associated with a wall void or other inaccessible space, a dust formulation which provides better residual activity should be used.
