first of all, instead of putting moldy cigars in a surplus humidor, throw them out, they are useless. And from what I have heard, cigars with mold don't have to come into contact with other cigars for the mold to spread, and it can spread like wildfire. Now you are sure it is mold, and not the white dust like substance that gathers on cigars as they age and mature? But throw out the moldy ones, otherwise the rest of the cigars in your surplus humidor will most likely also become infected. I had that problem in the past when I had humidors with trays, sometimes the cigars on the top tray right below the humidifier would get mold, eventually before I stopped using regular humidors I didn't even put cigars on the top tray unless I was going to smoke them very soon. These damn cigars can be so hard to take care of sometimes can't they? It isn't enough to pay $5 or $10 a stick, you would think for that price they could take care of themselves, but no, they need tender loving care.
