Carpet Beetle Infestation: Identification, Prevention, and Control


A carpet beetle is a small insect that is usually oval-shaped that could create an infestation when you’re not careful about them. They can cause a significant amount of damage to furniture, carpet, bedding, and more in the long run.

You wouldn’t want to leave these insects alone especially when you’ve spotted one already. The young ones and the larvae live off eating silk, wool, leather, and other natural fibers. Not only that, but they also consume pet hair, flowers, and plants.

One of the best ways to prevent the spread of insect infestations is to identify them from the get-go. Once you’ve marked where they hide and where they go for food, you can quickly plan how to control the pests with the help of professional pest control services.

Carpet Beetle Species To Be Aware Of

There are several carpet beetle types:

  • Common Carpet Beetle or the Anthrenus Scrophulariae (Linnaeus)
  • Varied Carpet Beetle (Anthrenus Verbasci)
  • Furniture Carpet Beetle or the Anthrenus Flavipes (Leconte)
  • Black Carpet Beetle or the Attagenus Unicolor (Brahm)

The common carpet beetle can cause the most damage even in its larval stage. These pests and bed bugs are not the same, although many people tend to confuse them with each other. Even if both are some similarities, the former are more attracted to natural fibers and are fond of damaging clothing, furniture, and rugs.

Not only that but carpet beetles will also consume felt located inside music instrument cases and under your lamps and furniture. The structure of their mouths is designed to chew more on fiber materials and plants. Unlike bed bugs, these pests won’t bite but it would feel like they’re biting you because of the long red hairs they possess.

Carpet Beetle Life Cycle

The insects lay eggs less than 1mm in length. Their eggs are white or cream-colored, and adults can lay about a hundred eggs at once. The hatching period takes around 10 days up to a month.

Furniture carpet beetles on the other hand can lay 60 eggs with a 9 to 16-day hatching period. The species’ larvae live around 70 to 90 days before they begin to pupate. The next stage of these insects is 14 to 17 days in pupa until they emerge as adults. A furniture carpet beetle has a lifespan of about 4 to 8 weeks.

You are dealing with dime-sized common carpet beetles that measure around 2.5 to 3.8 mm long in adulthood. They are quite small and the common carpet beetle has a striped black shell with orange yellow or white colors combined.
