Buy bags to vacuum the air out, for one month or two, they should be dead. Make sure the air is not getting in the bags, for that you need to buy good ones, I buy mine form ebay. walmart and other stores do not have the good quality ones, the air still gets in, Love the idea of using drapes. Made recently my own soap. Melted plain one, added bunch of spices I had in the kitchen, ginger, cayenne pepper, rosemary, all that stuff, feel difference of the soap.helps!
