Mid-Winter Hive Check

Local beekeepers took advantage of above-average January temperatures to check their hives. One found his hives full of bees and brood and, fearing swarming, asked me if he should split the colonies. I recommended that he wait while making sure that they have plenty of stored food and hive capacity. February is too early to divide colonies in central Arkansas. The bees, which are now protecting brood, need to have strong winter colonies to provide cluster warmth. Also, commercially produced queens are not available in the winter, and it’s a long time till colonies will be able to make their own queens. I suggested to the beekeeper that if he wants to increase his hive count, he should wait until there are plenty of drones walking on the combs before making splits. I like to see large numbers of adult drones on the combs to tell me when it is time to produce queens. With brood production increasing, colonies will continue to expand, experiencing an increased demand on their dwindling supply of stored honey. The maximum stressful situation will occur in March. As we approach March, colonies have large populations of bees, little natural forage, and no queens available.

With the beekeeper’s concern that his bees were crowding their hives, I suggested that he should try to suppress the bees’ urge to swarm by making sure that the colonies have plenty of hive capacity. He could, on a fairly warm day, add another box of drawn comb atop the existing hive bodies. Frames of capped honey should be placed directly above the brood nest. Since bees move upward in their hives over winter, when spring approaches, he can reverse the hive bodies to expand the available brood area. Warm weather in winter affords bees the opportunity to forage red maple, as in today’s photo. Red maple is a good source of pollen and nectar; however, in many years, cold or rainy weather prohibits bees from foraging this early-blooming tree.
