BLACK CARPET BEETLE( Attagenus spp.)
The adult is 2.8 - 5 mm in length. It is mostly dark brown to black in color. The larvae is long and carrot shaped with a tuft of hairs emerging from the rear end.
Food: The larvae of this pest will feed upon a great variety of animal and plant products, such as carpets, felt, woolen goods, skins, furs, stuffed animals, leather book bindings, feathers, horns, hair, silk, cattle hair, and insect meal. Also it will attack plant products such as seeds and grains, corn and cayenne peppers.
Life Cycle: The female Black Carpet Beetle will lay 42 - 114 eggs near a possible food source. The larval stage is the destructive stage. The period from egg to adult will last about 1 year, possibly more depending on environment.
Two types of insects are responsible for damage to wool clothing, wall hangings, feathers, silk garments, felt, furs, wool rugs and carpeting. In Wisconsin there are two species of clothes moths and several species of carpet beetles that attack natural fibers. Most damage is done during storage because these insects are most active in dark, undisturbed areas.
