Carpet beetles are small pests, typically measuring between 2 mm and 5 mm. They have short, clubbed antennae and a distinctive oval shape, often appearing in shades of dark brown to black. Some species, like the furniture carpet beetle, flaunt colorful scales—think white and yellow patterns on their thorax, with vibrant orange and red down their backs. Varied carpet beetles, on the other hand, sport a mix of white, brown, and dark-yellow scales that darken with age.

Signs of Infestation

While adult carpet beetles can be spotted on windowsills, it’s the larvae that do the real damage. Look for irregular holes in your carpets and fabrics; unlike moths, which create tiny holes everywhere, carpet beetles tend to munch on larger areas. You might also find cast skins from molting larvae, which can trigger allergic reactions in sensitive individuals.

Prevention Tips

To keep these pests at bay, regularly inspect your plants and flowers, as adult carpet beetles often hitch a ride into your home on them. A thorough vacuuming can eliminate lint, hair, and other debris that serve as food for larvae. Don’t forget to check window screens and vents for any potential entry points, and keep your rugs, drapes, and stored fabrics clean. If you find yourself facing a serious infestation, it’s time to call in the experts.

Where They Live

Carpet beetle larvae love dark, secluded spots. Outdoors, they can be found in bird nests and organic materials, while indoors, they thrive in air ducts, lint, and even dry dog food. Black and common carpet beetles prefer cooler climates, while varied carpet beetles enjoy warmer environments.

Life Cycle of Carpet Beetles

Carpet beetles go through four life stages: egg, larva, pupa, and adult. Females lay eggs near food sources like carpets and leather. Eggs typically hatch in about two weeks, and larvae can take anywhere from a few months to two years to mature, depending on the species. Once they pupate for one to two weeks, adults live for about two months.

FAQs

Why do I have carpet beetles?
They often enter homes on plants or flowers and lay eggs in cozy spots like carpets and wool. The larvae then seek out dark areas to grow.

How concerned should I be?
Carpet beetle larvae can damage fabrics and cause skin irritation with their bristly hairs. If you see adult beetles, it’s a sign that larvae or eggs are lurking nearby—time to call pest control!
