Wow, we are enjoying 75+ degrees here for the next few days before the temperatures get more seasonal. Last week we had a frost two mornings in a row, followed by two days of rain.
I installed 1/2” insulation board in the inner cover over the weekend because of the colder temps and then we have had this up tick of heat. The insulation addresses the tendency for condensation to develop on the underside of the inner cover which will then drip down onto the cluster of bees freezing them out. Honeybees can manage the cold but not the cold moisture on their bodies. The insulation is a buffer between the outside and inside temperature of the hive. Thus heat radiating upward from the cluster of bees when it hits the inner board will not condense.
I had concern the bees would get too hot since I have the entrances reduced and the insulated inner cover. But they are managing just fine. I still need to cut some quarter inch wire screen to use as a mouse guard. Nothing fancy but will work. When the temperatures get consistently cold I will wrap with black roof paper.
The Ohio State bee Inspector was here two days ago. All three of my hives are doing well. Healthy, well feed bees and a good queen have a better shot at making it through the Winter.
The apivar strips were removed yesterday. All the hives should be good until February when an alcohol test will be done and possibly do an oxalic acid vapor treatment if needed.
