I would NOT put the other four in your humidor yet!! First, put them into the freezer (in the bag)for about 2 days. Then remove them and put them in the refrigerator for a day or two, then into your humidor. This will kill and beetle eggs that may be on the other cigars. As for the celephane, I thought it would keep the beetles out, but have heard cases where the beetles eat right through it!! Hope this helps! Happy smoking all!
