Have you ever wondered what kind of a black bug with white stripes on back crawls across your pricey carpet that is lavishly furnished? Carpet beetles are little black bugs with white stripes. The pests prey on numerous other materials made of wool, fur, felt, silk, feathers, skins, and leather, just like clothes moths do. 

These substances include keratin, a fibrous animal protein that the larvae can consume. Cotton and synthetic textiles, like polyester and rayon, are generally resistant to attack, unless they are extensively stained with body oils or combined with wool. Unnoticed carpet beetle infestations can spread and destroy delicate things.

General Appearance

These insects, which measure between 2 and 5 mm in length and are also known as furniture beetles, various carpet beetles, or black carpet beetles, are relatively little. They could appear to be dark brown or bug with black and white stripes. Even though there are various varieties of carpet beetles, they typically have some traits in common, such as an oval shape and distinctly small antennae that are grouped.

Evidence of Carpet Beetles

If carpet beetles invade a home or building, they will leave behind signs of their presence. There will be harm done to the carpets, clothes, hair, and fur of animals. In fabrics, carpet bugs will gnaw erratic holes. It is unknown if carpet beetles consume synthetic fibers. They will consume animal remains as food as well. Additionally, frequently discovered in food goods including cereal, pasta, and almonds are carpet beetles.


Apart from cotton, diet carpet beetles consume a wide range of other dietary items, such as animal materials like skin, fur, feathers, and wool as well as dead insects. Since synthetics cannot be digested, carpet beetles do not eat them as larvae. Additionally, they occasionally eat grain-based foods and various dried dairy products. They can consume plant-based foods like flowers as well.


Carpet beetles are regarded as one of the harmful black bugs with white stripes that are most prevalent worldwide. Due to their ability to eat a wide array of foods, including fibers, plants, and animal products, they can thrive in various situations. Between the larval and adult phases, a carpet beetle must go through multiple molting processes. When they are larvae, they are drawn to warm, gloomy surroundings, but when they are adults, they are drawn to light.


Carpet beetles can survive just fine in both indoor and outdoor circumstances; however, females typically prefer to lay their eggs in areas with an ample supply of food for the developing larvae. Most of these components enter a home through doors, windows, or other small openings. They also live in other animals’ or birds’ nests. They can be found in chimneys and walls, where they consume extinct animals and insects for food.

Controlling Carpet Beetles

There are ways to help, even if carpet beetles are a challenge to manage as a pest. Be sure to carefully seal all your food. Containers for storing food are excellent to use. Regularly brush away any pet hair. Maintaining clean, clutter-free flooring is crucial. To protect them against carpet beetles, clothing made of wool, leather, or silk should be stored in airtight plastic containers. Any fabrics that have been impacted by carpet beetles should be dry cleaned.

Removal of carpet beetles

The easiest technique to get rid of carpet beetles if you discover signs of them in your home is to vacuum and then steam clean the affected area.

The Bugman, a pest management business in the Pacific Northwest, and other internet resources for pest control advise washing tainted pillows or textiles in hot water with detergent and wiping off any suspected carpet beetle habitats with pure vinegar.

Boric acid sprinkled on furniture, carpets, or rugs will also eliminate any leftover insects. After two hours, vacuum up the boric acid dust after it has been sprinkled. Get rid of that vacuum bag right away.


  • How do carpet beetles spread?

Where food is plentiful, carpet beetles like to deposit their eggs on animal-derived larval foods like wool carpets, clothing, furs, and museum specimens. They can lay more than 100 eggs at once. It can take these eggs 10 days to a month to hatch.

  • Do carpet beetles bite or larvae people?

People are not bitten by carpet beetles or their woolly bear larvae. The rough hairs of carpet beetle larvae irritate the skin, yet the rashes brought on by carpet bugs as described above can resemble rashes. If you’re getting bitten by something, it’s probably not carpet beetles or their larvae but rather a completely new issue.

  • Do carpet bugs have wings?

Yes, carpet beetles can fly, and they may also enter your home through open windows, which is how you first become infested with them. Carpet bugs’ capacity to fly, however, just serves to increase their annoyance and facilitates their proliferation throughout your home.
