Carpet beetles make their way into a home on flowers and through windows or doors, multiplying when suitable food sources, such as pet fur, wool or silk, are available. This allows the larvae to feed, which creates another batch of eggs. After a few cycles, the home could have an infestation of hundreds or thousands of beetles, depending on the abundance of food.
A carpet beetle infestation can lead to holes in clothing or carpets made from natural fibers. This damage often looks similar to what a moth would do to these fabrics.
Keeping the home free of pet hair and other items that carpet beetles eat works best when eliminating them from the home. Throwing out badly infested items can also keep their numbers low and allow the homeowner to keep the problem under control. In more severe cases, chemical treatment might become necessary.
