Spring is here; at least today. Next week looks like another chance of snow!!! But on this spring like day I was out treating survivor colonies with Oxalic acid vapor. While out and about I heard and saw the honey bees up in maple trees gathering pollen. They were returning to their hives with a pale gray/yellow load in their pollen baskets. I also received reports that pussy willows are now in bloom.
I had just finished gassing this hive with oxalic acid vapor. When I had plugged the upper hole and bottom entrance there were only about 10 bees present. This crowd of bees returned in only the 5 minutes of the treatment. They must have been furiously working nearby maple trees.
