Almost two weeks ago we had a big snow and then a few days later it was warm. Came home from work late afternoon and found a few hundred of bees seemingly dead in the snow in front of my hives. Some were probably dead already and cleaned out, but many, up to 20-30 feet away, had either gotten cold or landed in the snow.
Now again, it's happening. Big snow yesterday, today warm (in the 40s) and sunny. Lots of bees in the snow. Why do they do this? And anything I can do to stop it? I think I'll put come cardboard down in front of the hives.
Last time I scooped up about 20 and brought them in the house and warmed them and they revived. But there were too many and it was too late do do anything else.
