Hi All: Read somwhere that CO2 will kill wax moth eggs. Has any one tryed to use Dry Ice ? One could stack up the supers and seal them up with duct tape and put the dry ice on the top and the CO2 , being heavier than air, will sink to the bottom as it sublimes. Hope some one has tried it. I don't want to loose comb in the control of the experiment. Thanks in advance. James Peterson
