No, and I am not exposing them to the cold during a vaporization treatment. In the winter (when it becomes cold) where I am located the bees will brood less or not at all. Most of the varroa mites will be phoretic, attached to the bees, or walking around the hive not in brood cells. This is where oxalic vaporization works best. It kills mites walking around the hive or attached to the nurse bees. It does not penetrate brood cappings, so it cannot kill mites under the cappings. OA dribble is a much different method, and in many beekeepers opinions, a much more difficult method to get consistent results.
So you want it cooler so you coat more bees despite exposing them to cold? I plan on doing a OA dribble.
