Carpet Beetles: Identification, Damage, and Control

Carpet beetles are common household pests that can cause damage to carpets, clothing, upholstery, and other natural fiber materials. These small beetles are often overlooked until infestations become severe.

Identification of Carpet Beetles

• Adult Carpet Beetles:

  • Oval-shaped, about 1/16 to 1/8 inch long.

  • Color varies depending on species, often with a mottled pattern of white, brown, yellow, or black.

  • Found near windows, lights, and in dark, undisturbed areas.

• Carpet Beetle Larvae (Most Damaging Stage):

  • About 1/8 to 1/4 inch long.

  • Covered in bristle-like hairs.

  • Brownish and slow-moving, often found in closets, under furniture, or in stored fabrics.

Damage Caused by Carpet Beetles

• Textile & Fabric Destruction:

  • Larvae feed on natural fibers such as wool, silk, leather, fur, and feathers.

  • Damage appears as irregular holes or bare patches on clothing, rugs, or upholstery.

• Contaminated Food Products:

  • Some species infest dried food products like grains, flour, and pet food.

• Allergic Reactions:

  • The bristles of carpet beetle larvae can cause skin irritation or allergic reactions in some people.

Prevention & Control

1. Cleaning & Maintenance

• Vacuum carpets, furniture, and baseboards regularly to remove larvae and eggs.

• Wash and dry infested clothing and fabrics at high temperatures.

• Store wool, silk, and fur items in airtight containers.

2. Eliminate Food Sources

• Keep food and pet food in sealed containers.

• Remove old bird nests or dead insects in attics and basements, as carpet beetles may feed on them.

3. Use Insecticides & Natural Repellents

• Apply boric acid or diatomaceous earth in cracks and crevices.

• Use insecticides labeled for carpet beetle control (e.g., pyrethrin sprays) in infested areas.

• Cedar and lavender sachets can help deter carpet beetles in closets and storage areas.

4. Professional Pest Control

• For severe infestations, consider hiring a pest control service to apply targeted treatments
