Here in the Ottawa River valley, we had our first overnight killer frost last week. (Oct. 20) Since then, the daily high temperature has averaged out at about 12-15 Celcius (53-59 F.). My bees have been fairly active when the sun has been shining on the hive bodies (2 stories high). They are still greedily taking down medicated sugar syrup from feeder pails. This weekend, I plan to wrap each hive, as I have done in the past, in old carpeting with flaps for access and ventillation.
