Storage Techniques for Wool Blankets
Storing wool blankets properly will prevent moths from feasting on the blankets. Moth balls contain naphthalene or paradichlorobenzene. In a tightly sealed container, the vapors from mothballs become highly concentrated and will repel adult moths and kill larvae. These vapors will also degrade plastic materials in the immediate area. Does this Spark an idea?

Launder
-
Dry clean wool blankets to remove body oils and kill eggs and larvae before storing for the season. Do not wash wool blankets in the washing machine because the twisting and turning will stretch the material and ruin its finish. Allow damp or wet wool to dry away from a heat source to prevent shrinking.
Preparation
-
Insert white tissue paper in between the folds of the blankets to prevent wrinkling and store in an airtight plastic bag. Squeeze out excess air or use a bag that can be vacuumed sealed.

Cedar and Plastic Storage
-
Use a cedar chest or plastic storage container only if the containers can be tightly sealed. Cedar will lose its oil protective properties over time and plastic containers with loose-fitting lids will allow moths to gain entry and eat through the wool. If using mothballs, check the plastic container at the end of the season for softened or weak spots. If any are found, discard container.
Mothballs
-
Make a pouch of loosely woven fabric to place mothballs in the same container as the blankets. Do not allow moth balls to come in contact with the blankets and use additional tissue paper to form a barrier between the mothball pouch and the blankets if necessary. Keep mothballs away from pets and children to prevent poisoning.
