Alphabetical List of Critters - Carpet Beetles
Four species of carpet beetles are of major concern in Maine. Most important is the Black Carpet Beetle, which is black in color (as its name implies), oval and less than 1/4 inch long. The beetles are good fliers and are attracted to light, so finding adult beetles on window sills is often the first sign of infestation.
The larval stage does most of the damage. Even though they are called carpet beetles, the larvae feed on many other items. Preferred foods include animal products, such as skins, furs, feathers, wool, hair and dead insects, but they also eat cotton to some extent. They are known to eat holes in yarns that are blends of wool and synthetic fibers.
