Winter Oxalic Acid Vapor Treatment in the Apiary

It’s mid-January and we have had quite a long cold spell so it’s the perfect time for treating for bee colonies with Oxalic Acid vapor as brood rearing should be at a minimum. Yesterday’s temperatures were a little over 40 degrees and there was no wind — a perfect day for the vaporizer.¬†When the vapor hits the cluster a strong colony like the one in this little Nuc will roar as it fans and moves the air around. It’s nice confirmation in the wintertime that the colony is alive and strong.
