Carpet beetles mostly eat carpet, wool, dead insects, furs, hides, feathers, horns, hair, silk and bones. These beetles are found in attics, wool carpets, tapestries and wall-to-wall carpeting so they can ruin clothing, upholstery and carpeting by eating it.

Powder post beetles fly and are attracted to light. They usually feed on hard woods and are found in hardwood floors, timbers and crates, antiques and other things made of hard wood. They can kill or damage trees and things made from wood, such as furniture. There are even documented cases that powder post beetles have destroyed houses.
