What are Carpet Beetles?

Carpet beetles are small, oval-shaped insects that are part of the Dermestidae family. There are several species of carpet beetles, but the most common ones in homes are the varied carpet beetle, the black carpet beetle, and the common carpet beetle. Adult carpet beetles are usually less than 1/4 inch long and have a mottled appearance. Their larvae are covered in small hairs and are often referred to as “woolly bears” because of their fuzzy appearance.

Signs of a Carpet Beetle Infestation

There are several signs that homeowners should look for if they suspect a carpet beetle infestation. These include:

  • Small, oval-shaped beetles on walls, floors, or windowsills
  • Small holes in carpets, clothing, or other fabrics
  • Shed skins or fecal pellets of carpet beetle larvae
  • An unpleasant odor caused by dead carpet beetles

Causes of Carpet Beetle Infestations

Carpet beetles are attracted to natural fibers, such as wool, silk, and cotton. They can also be attracted to pet hair, feathers, and dead insects. Homeowners can unwittingly bring carpet beetles into their homes on clothing, furniture, or other items that have been stored in areas where carpet beetles are present. Poor housekeeping and infrequent cleaning can also contribute to the growth of carpet beetle populations.

Prevention of Carpet Beetle Infestations

There are several steps that homeowners can take to prevent carpet beetle infestations. These include:

  • Regular cleaning and vacuuming of carpets, furniture, and other fabrics
  • Proper storage of clothing and other items in sealed plastic containers
  • Regular washing of bedding and linens
  • Elimination of any dead insects or birds from the home
  • Sealing of cracks and crevices in walls and floors to prevent entry of carpet beetles

How to Get Rid of Carpet Beetles Naturally

There are several natural methods that can be used to get rid of carpet beetles. These include:

  • Freezing infested items: placing infested items in the freezer for at least 72 hours can kill all life stages of carpet beetles.
  • Heat treatment: exposing infested items to high temperatures (above 120°F) can kill carpet beetles.
  • Diatomaceous earth: this powder, made from the fossilized remains of marine phytoplankton, can be sprinkled on carpets, furniture, and other fabrics to kill carpet beetles.

Chemical Treatments for Carpet Beetle Infestations

In severe cases, homeowners may need to use chemical treatments to eliminate carpet beetle infestations. These treatments should be used with caution and only as a last resort. Common chemical treatments for carpet beetles include:

  • Insecticides: these can be applied directly to infested areas, such as carpets, furniture, and closets. Some insecticides may also be used to treat cracks and crevices in walls and floors.
  • Insect growth regulators: these are chemicals that prevent the development of carpet beetle larvae, preventing them from maturing into adults and reproducing.

How to Clean and Protect Your Home from Carpet Beetles

Cleaning and maintaining a clean home is essential in preventing carpet beetle infestations. Here are some cleaning tips to help protect your home from these pests:

  • Vacuum carpets, furniture, and other fabrics regularly to remove any carpet beetle eggs or larvae.
  • Wash bedding, curtains, and other linens in hot water.
  • Store clothing and other items in sealed plastic containers.
  • Eliminate any dead insects or birds from the home.
  • Seal cracks and crevices in walls and floors to prevent entry of carpet beetles.

A professional can assess the extent of the infestation and recommend the best course of action to eliminate the pests.
