Carpet Beetle Treatment

Carpet beetles like to hide in storage containers or underneath your furniture. These insects can cause great damage to priceless items or family heirlooms. Treatment can be time consuming, as the insects are resilient and their eggs will continue growing into adults unless proper cleaning is performed. Does this Spark an idea?


Vacuum the infected area immediately, sucking up adults and larvae. Carpet beetles can be safely vacuumed from the floor area and from inside any storage chests and closets.

Cleaning Materials and Storage

Carpet beetles look for sources of food, mostly fabrics, and can cause damage when feeding on animal fibers such as wool, fur, feathers and hair in clothing, carpeting, upholstery and other household furnishings. Treat clothing that is safe for machine washing with laundry detergent, just as you would during pre-washing procedure, by pouring detergent on materials. Place items in the washing machine and wash with hot water and laundry detergent.

Place items that are not safe for washing machine cycles in a plastic zipper bag and put in the freezer for 48 hours. Dry cleaning and ironing will also kill adults and larvae.

Borax powder or Boric Acid can be sprinkled on infested areas, but wear gloves when handling borax as it can cause skin irritation for some people.

Place mothballs inside storage containers, but try avoid crystals (naphthalene) as they can cause an unpleasant smell that is hard to get rid of.


Black Flag, Ortho, and Raid make insecticides that will kill carpet beetles. The insecticide is usually in an aerosol spray can. Spray the insecticide in chests, boxes, closets, attics, basements, floor cracks, registers, or cold air ducts, on baseboards, moldings and trim. Read instruction labels to see if you can spray insecticide on fabrics, linens and on upholstered furniture.

Carpet Cleaning

Adult carpet beetles will feed on pollen, while larvae feed on lint. Their favorite places are carpeted areas, especially around trim where dust and lint collect. Carpet cleaning may be necessary as carpet beetle eggs are resilient. A professional carpet cleaning service would need to steam all carpeted areas and treat them with cleaning chemicals to kill the pests and stop further infestation.
