5 Things to Know About the Varied Carpet Beetle
The varied carpet beetle (Athrenus verbasci) is a tiny but destructive pest that can cause serious damage to household items and museum collections. These beetles are particularly known for feeding on natural fibers and stored organic materials. Here are five key things to know about the varied carpet beetle and how to protect your belongings from an infestation.
1. Varied Carpet Beetles Have a Distinctive, Speckled Appearance
Unlike many other household pests, varied carpet beetles are small, oval-shaped beetles with a mottled pattern of white, brown, yellow, and black scales on their wing covers. This coloration gives them a speckled or “varied” look, which is how they got their name. Adults are often found near windows as they are attracted to light.
2. The Varied Carpet Beetle Larvae Are the Real Problem
While adult varied carpet beetles primarily feed on pollen and nectar, the larvae are responsible for causing damage. These small, brown, hairy larvae, often called “wooly bears”, feed on natural fibers like wool, silk, leather, fur, and feathers. They can also infest stored food products, such as dry pet foods and cereals. Their bristle-covered bodies can cause allergic reactions in some people.
3. Varied Carpet Beetles Can Infest Homes, Museums, and Storage Areas
Varied carpet beetles are notorious for infesting homes, museums, and storage areas, where they can cause damage to textiles, taxidermy, and insect collections. Museums and historical archives must take special precautions, as these pests are attracted to animal-based materials, including wool rugs, fur garments, and preserved specimens.
4. Varied Carpet Beetles Often Enter Homes Through Open Windows and Infested Items
Varied carpet beetles can find their way indoors in several ways:
Flying in through open windows and doors - especially in spring and summer when adults are most active.
Hitchhiking inside on infested clothing, furniture, or secondhand goods.
Laying eggs in cracks, crevices, air ducts, and attics, where larvae can develop unnoticed.
5. Prevention and Early Detection Are Key
To avoid a varied carpet beetle infestation:
Regularly vacuum carpets, furniture, and storage areas to remove eggs and larvae.
Store wool, silk, and fur items in airtight containers with moth-resistant materials.
Inspect secondhand furniture, rugs, and clothing before bringing them inside.
Use pheromone traps to detect and monitor beetle activity early.
Seal cracks and crevices to prevent beetles from laying egg in hidden areas.
