We're battling the buggies down here in the deep and humid South and need dessicant packets (the little salt looking packets that come with new shoes). We're packing some of our paper and fabric items in well sealed plastic bins and would like to throw a dessicant packet in each. Anybody know - - where you can get dessicant packets (American hardware chains or big box retailers)? - what are some of the brand names that they are sold under? - what is the chemical name I am looking for? Thanks!
