Do I have a Bed Bug or Carpet Beetle?

Bed Bug vs Carpet Beetle: The Differences


The most significant difference between the bed bugs and carpet beetles is that carpet beetles don’t bite, and bed bugs do. Bed bugs need blood to grow and reproduce. Like a mosquito, a bed bug will stick its elongated nose into your skin and extract your blood. This usually leaves red bite marks that can itch.

If you’ve heard of carpet beetle bites, they’re simply an allergic reaction to the hair on the larva’s body. Carpet beetle larva are covered with spiky hair bristles, similar to a fuzzy caterpillar. When they crawl over some humans who are allergic, these prickly hairs can cause a reaction that looks like a bite.

Instead of blood, carpet beetle larvae eat organic matter in the form of wool, fabric, carpet, leather and feathers. They are voracious for their size and capable of damaging rugs, garments and upholstered furniture. Their path of destruction continues until they are able molt enough times to become an adult. Once a carpet beetle becomes an adult, it shifts its diet to pollen.

In addition to dietary differences, bed bugs and carpet beetles look different:

Bed bugs are small, oval-shaped and reddish brown or tan in color. Their bodies are flat and about the size of an apple seed. The don’t have wings and are not able to fly. They are nocturnal and prefer quiet dark areas like under mattresses.

Carpet beetles are also oval shaped but are black, brown, white or orange and often have a molted pattern. They have wings and can fly to new locations. Adults are attracted to windows and areas of light.

How You Get Carpet Beetles vs Bed Bugs

Bed Bugs and carpet beetles often travel in similar ways. Both are hitchhikers that latch on to clothes, luggage or furniture in order to find new feeding grounds.

Bed bugs are notorious for travelers. They crawl into suitcases or purses and then spread through airports and hotels, ultimately arriving in your home. They will lay eggs and produce nymphs (baby bed bugs) that continue the cycle of feasting on your blood and creating more bed bugs.

Carpet beetles sometimes hitchhike. They also lay their eggs in food sources like carpeting and blankets. An adult might fly in through and open window or door and deposit the next generation in your bedroom. Carpet beetle nymphs will devour your carpets and fabrics until they reach adulthood and then fly off in search of pollen.
