Getting Rid of Carpet Beetles

Carpet beetles can be a frustrating household pest, infesting carpets, furniture, and other fabric items. These small insects are often overlooked until damage becomes visible, as they feed on natural fibers like wool, silk, leather, and even hair and feathers. Carpet beetle larvae are especially destructive, as they burrow into fabrics, leaving holes and damaging valuable items.

In this guide, we’ll cover everything you need to know about identifying carpet beetles, understanding their lifecycle, and, most importantly, how to eliminate them and prevent future infestations.


What Are Carpet Beetles?

Carpet Beetle

Carpet beetles are tiny, oval-shaped insects that belong to the family Dermestidae. While adult carpet beetles feed primarily on pollen and nectar, their larvae are known for damaging carpets, upholstery, clothing, and other household items containing natural fibers.

There are several types of carpet beetles, with the most common species being:

  • Black Carpet Beetles: Black or dark brown in color.
  • Varied Carpet Beetles: Black with white, brown, and yellow patterns.
  • Furniture Carpet Beetles: Similar to varied carpet beetles but with a more rounded shape.

Carpet beetle larvae, sometimes referred to as “woolly bears,” have bristly hairs and a segmented, worm-like body. They can grow up to 5 mm in length and are usually tan to light brown in color.


Signs of Carpet Beetle Infestation

To effectively get rid of carpet beetles, it’s essential to recognize the signs of an infestation early. Here’s what to look for:

  1. Shed Skins and Fecal Pellets: Carpet beetle larvae shed their skin multiple times as they grow, leaving behind small, shell-like casings.
  2. Visible Larvae: You may spot small, hairy larvae crawling on carpets, rugs, clothing, or upholstery.
  3. Damage to Fabrics: Check for small holes in carpets, wool clothing, blankets, upholstered furniture, or curtains.
  4. Dead Adult Beetles: Adult beetles are attracted to light, so you may find them near windowsills or light fixtures.

How to Get Rid of Carpet Beetles: Step-by-Step Guide

Here are the most effective methods to eliminate carpet beetles from your home. Following these steps diligently will help remove the infestation and protect your belongings.


1. Vacuum Thoroughly and Regularly

Vacuuming is one of the most effective ways to remove carpet beetles and their larvae from carpets, furniture, and other fabric surfaces.

  • Vacuum All Areas: Focus on carpets, rugs, under furniture, baseboards, and other areas where carpet beetles may hide. Don’t forget upholstered furniture, drapes, and even mattresses.
  • Empty the Vacuum: Immediately dispose of the vacuum bag or empty the canister outside, as beetles and larvae can survive inside the vacuum and reinfest your home.
  • Repeat Regularly: Vacuum daily during the early stages of an infestation to prevent eggs from hatching and larvae from spreading.

2. Wash Affected Fabrics

To kill carpet beetles and remove their eggs, wash all infested or potentially infested fabrics.

  • Hot Water Wash: Wash all washable fabrics (clothes, bedding, curtains) in hot water to eliminate eggs and larvae. Use the highest temperature setting recommended for each item.
  • Dry Cleaning for Delicate Fabrics: For non-washable items like wool or silk, take them to a dry cleaner, as dry cleaning kills carpet beetles without damaging delicate fabrics.

3. Use Insecticides

For severe infestations, insecticides can be effective at killing carpet beetles and preventing further spread. Use insecticides carefully, and only on areas that won’t come in direct contact with people or pets.

  • Choose the Right Insecticide: Look for insecticides with active ingredients like cyfluthrin, bifenthrin, or deltamethrin, specifically labeled for carpet beetles.
  • Apply to Problem Areas: Spray insecticides along baseboards, under furniture, and on carpeted areas where beetles are present.
  • Avoid Treated Areas: Keep pets and children away from treated areas until the insecticide has dried.

Note: Follow all safety instructions on the insecticide label, and consider wearing gloves and a mask while applying.


4. Use Boric Acid

Boric acid is a natural insecticide that is effective against carpet beetles and other pests. It can be safely used on carpets and upholstery as long as it’s applied correctly.

  • Apply a Light Dusting: Sprinkle a thin layer of boric acid on carpets, rugs, and upholstered furniture.
  • Work It In: Use a soft brush to work the boric acid into the fibers.
  • Vacuum Up Residue: After a few hours, vacuum thoroughly to remove the boric acid and dead beetles.

5. Try Natural Remedies (Essential Oils)

For a chemical-free approach, essential oils can help repel carpet beetles and prevent further infestation.

  • Use Cedar Oil: Cedar oil is known for its insect-repelling properties. Spray diluted cedar oil (a few drops in water) on carpets, furniture, and other vulnerable areas.
  • Use Lavender and Eucalyptus: Lavender and eucalyptus oils have insect-repelling properties and are safe for most fabrics. Place sachets of these oils in drawers, closets, and storage areas to deter beetles.

6. Seal and Store Items Properly

Once your home is free of carpet beetles, it’s important to store vulnerable items in a way that prevents future infestations.

  • Use Plastic Storage Containers: Store wool, silk, leather, and other natural-fiber clothing in airtight plastic containers, as carpet beetles cannot chew through plastic.
  • Use Cedar Blocks or Mothballs: Place cedar blocks or mothballs in storage areas to add an extra layer of protection.
  • Keep Storage Areas Dry: Carpet beetles are attracted to moisture, so avoid storing clothing in damp or humid areas.

How to Prevent Future Carpet Beetle Infestations

Once you’ve gotten rid of carpet beetles, it’s essential to take preventive steps to avoid future infestations. Here are some preventive measures:

  1. Regular Vacuuming and Cleaning: Vacuum carpets, rugs, and upholstery weekly, especially in areas near windows and baseboards.
  2. Store Seasonal Clothing Properly: When storing seasonal items like winter coats or woolen blankets, seal them in plastic and keep them in a cool, dry place.
  3. Inspect New or Second-Hand Items: Check second-hand items like clothing or rugs before bringing them into your home to ensure they’re free from carpet beetles.
  4. Use Pheromone Traps: Pheromone traps designed for carpet beetles can help monitor and control any potential infestations.
  5. Control Humidity: Carpet beetles thrive in humid environments. Using a dehumidifier in storage areas can reduce moisture and make your home less hospitable to pests.
