Carpet beetles can be killed using a variety of methods, including natural and chemical solutions. Here are some effective ways to get rid of carpet beetles:

• Vacuuming: Regularly vacuuming carpets, rugs, and upholstered furniture is an effective way to remove food sources as well as carpet beetle eggs, larvae, and adults.

• Boric acid: Sprinkling boric acid on carpets, rugs, and furniture can be lethal to carpet beetles. Leave it for a couple of hours, then vacuum the areas well. Make sure that children and pets do not come into contact with the areas treated with insecticide.

• Vinegar: Mix equal parts white vinegar with water and use a spray bottle to lightly coat carpets and other fabric-based areas. Vinegar is naturally effective against carpet beetles due to its acidity.

• Diatomaceous earth: This fine white dust found in the earths surface kills carpet beetles and their larvae. Be sure to request food-grade diatomaceous earth, which is low in crystalline silica and is considered safe for humans.

• Chemical insecticides: Products containing bifenthrin, deltamethrin, or cyfluthrin can be effective against carpet beetles. Always test first on a small, inconspicuous area to ensure your carpet wont be damaged or stained.

Its important to note that carpet beetles can be difficult to control and may require a combination of methods. Additionally, prevention is key to avoiding infestations. This includes regular cleaning, eliminating accumulations of lint, hair, dead insects, and other debris that serve as food for carpet beetles, and sealing off any crevices between the outdoors and indoors of the home.
