Their names may indicate that they just eat carpets but this is far from true. Carpet beetles can cause damage to a wide variety of materials of animal origin. When you see flying or crawling adult carpet beetles, it may indicate the presence of an infestation. You may also see damaged materials or sand-like larval droppings. This will confirm their activity.
Adult carpet beetles are quite small – only 5mm in length – and oval-shaped. Larvae are usually a reddish-brown colour and are covered with stiff bristles all over their bodies.
