Adult carpet beetles are about an eighth of an inch long, and round in appearance. The backs of the insects have much the same color scheme as the larvae. The larvae have small, hairy, soft bodies about a quarter inch long, depending on the instar. The larvae feed on a wide variety of foods, including carpets, furs, woolens, skins, stuffed animals, leather, feathers, silk and many plant products. The adults feed on nothing except pollen and nectar from flowers outside.
In spring and early summer, the adult will lay up to a hundred eggs, usually cemented to the product, or on furs, woolens or any dried natural or animal material. The eggs hatch in about three weeks.
The larval stage can withstand a long period of no food, and can molt as many as 30 times. They also prefer clothes or fabrics soiled with perspiration, body oils and urine. As with Black Carpet beetles, the adults will pupate in the last larval skin and use the last skin to hide in for as long as a month.
My guess...
