Carpet beetle is a type of bug known for its affection for eating wool, silk, and fur. Damage caused by its larvae can be mistaken for moth damage or a simple tear and wear. Females can lay 50 to 100 eggs on average, and the larvae do most of the damage to the rug, feeding on the keratin and chitin in the natural fibers. Once the infestation has reached this advanced stage, it can spread to other parts of the home.
