Check your garments occasionally to make sure that you don’t have a moth or moisture problem. With proper care, wool can be a durable and long lasting fiber. Always care for your garment following the instructions on the care label. Perspiration and food stains attract moths. Brushing your jumper with a wool brush can loosen eggs, and simply popping your sweater into the freezer before you store it will kill them. Another tip is to store your sweater in a sealed clean plastic bag. This will prevent moths from attacking it. Be very careful if using moth balls and crystals as they may be harmful to children and pets.
