There are several ways to protect your woolen blankets during storage. 1. When storing for a long time, store clean blankets in airy shelves that don't have places that moths can thrive in. They just love to get into dark, damp, airless corners. Take the blankets out regularly to air them, giving them a good shake and perhaps air them in a warm garden for a couple of hours. Moth and moth larvae really hate to be disturbed. 2. Pack clean dry blankets in vacuum storage packs. These will keep your blankets safe from moths for many months. A brilliant solution for packing large blankets away for the summer. 3. Use red cedar wood placed in between the layers of your folded blankets. They have a lovely smell and the oils in the wood are said to kill the moth larvae. Again, it is wise to check blankets every few months as these are not always 100% effective. You can buy cedar chest to store all your bedding in. 4. Mothballs or moth crystals can be placed near your blankets. These contain some nasty chemicals and insecticides, so only use these as a last resort. This is an excellent solution to consider if you have a bad infestation.
