How to Kill Carpet Beetle Larva

Updated April 17, 2017

Carpet beetles are annoying pests for any home. They get into furniture, carpet, wood, and anything else that they can chew on. Their larva which resembles a caterpillar feeds on everything, including dead skin cells and faeces. However you can remove these bugs and prevent them from coming back.

Identify the type of carpet beetle infesting your home. The three types of carpet beetles include the varied carpet beetle, furniture carpet beetle and black carpet beetle. The varied carpet beetle is small, round with dull brown, black, and white shell. The furniture carpet beetle is also round with a yellowish spotted shell, and the black carpet beetle is oblong-shaped with a shiny black shell.

Pull up carpets, check underneath furniture cushions, rugs and wooden objects to find the source of the problem. Carpet beetles like to eat anything, from carpet to faeces, pet food to dead insects.

Vacuum your entire home. Make sure to vacuum all carpeted areas and fabrics.

Wash fabrics in hot, soapy water to kill carpet beetles, larva, and their eggs. Anything that you can put in the washer, you should immediately do so, including piles of dirty clothes on the floor or old rags in the garage corner.

Steam clean the carpets by hiring a professional, renting a steam cleaner vacuum from a local supply store, or using your own steam cleaner. Most professional steam cleaners have a package designed to get rid of bug infestations in carpets.

Use boric acid on your carpets and fabrics to kill the bugs and to prevent any new carpet beetle invasion. Boric acid is a bleaching agent, so be sure to sprinkle lightly and vacuum within two hours to remove the boric acid and dead carpet beetle larvae.

Buy a carpet beetle prevention spray. Gentrol is just one brand of carpet beetle dust that you can also use to continuously protect against a carpet beetle infestation.
