Carpet Beetle Infestation: Identification, Prevention, and Control

Tiny holes in woolens, shed skins near baseboards, or larvae in closets? You may have carpet beetles. These pests feed on natural fibers (wool, silk, fur, feathers), pet food, spices, and even books.

Identification

Adults are small, oval, often patterned. Larvae are hairy, carrot-shaped "woolly bears." They prefer dark, undisturbed areas: under furniture, in closets, behind baseboards, in air ducts.

Prevention & Non-Chemical Control

• Vacuum thoroughly and frequently (carpets, upholstery, vents).
• Store susceptible items in airtight containers.
• Heat-treat infested clothing (dryer on high 30+ minutes).
• Expose items to sunlight—larvae flee light.
• Remove dead insects, rodent nests, and bird nests from attics/vents.

When to Call a Pro

For widespread infestations, professional pest control (e.g., Ross Environmental Solutions in NJ) provides targeted insecticide applications, fumigation if needed, and long-term monitoring. DIY pesticides often fail due to hidden populations.
