An adult carpet beetle won't cause your home any harm. Unfortunately, the same cannot be said of their larvae. Carpet beetle larvae can eat holes in rugs, curtains, upholstery, clothing, and books. You may not even know you have an infestation until you notice the damage the pests have already caused. If you spot something suspect, roll up your sleeves and clean. Thoroughly dust and vacuum to remove dust bunnies and cobwebs that shelter these pests. Then, remove clothes from your closet and storage bins, and wash everything or send it to the dry cleaners. Finally, treat your rugs with an insecticide, boric acid, or diatomaceous earth to kill any larvae that remain.
