Inside homes, these “fuzzy” bugs are often found on the floor or around baseboards, in closets, beneath upholstered furniture and on the undersides of carpeting. The larvae feed on things like animal furs, feathers, human hair, pet hair, silks, book bindings, and other like items.
Adult carpet beetles will feed on seeds, plants, and flowers during their short lifetime and frequently enter into homes and buildings from the outside. They enter through small cracks and openings around windows, doors, and in exterior walls. They will also use the spaces around electrical lines, above-ground pipes and other utility entrances that lead into a home.
Carpet beetle larvae are covered in bristles and if they come into contact with a person they can cause a minor skin irritation.
