If you suddenly spot an army of slow-moving, round, black bugs inside your home, there’s a good chance you’ve met your first carpet beetles. These tiny pests look harmless, but they can do some hefty damage. (Want to know something truly gross? The name “carpet beetle” comes from their love of eating carpet and laying eggs there. Yuck.)
“On warm spring days, adult carpet beetles can easily make their way inside through open windows or doors,” says Michael Bentley, board-certified entomologist and director of training and education for the National Pest Management Association. Once inside, they can lay eggs that hatch into larvae that will damage fabrics, carpets, and other items made from natural fibers.
