Something I just thought of for those of you who live in high humidity areas, including New York and much of the east coast this spring/summer. I saw for sale, somewhere, a brown disc of some sort that's purpose was to keep in your container of brown sugar to absorb the humidity so your sugar didn't turn into a rock. Perhaps something like this or some other sort of dehydrator would work if you were to keep them right in the bin with your worms?
