Honey Bees in the Winter

When it gets too cold for the honey bees to leave their hives it can be much harder to tell how the colony is doing. The hives look pretty lifeless on a cold winter day. There may be some dead bees scattered at the entrance. This is actually a good sign, especially if they are recently dead and as long as there aren’t too many of them. It means there are still live bees inside, and they’re cleaning out the dead. If there’s a warm day and the bees can leave the hive, they’ll clean off the entrance board of their hive and fly the dead bees away from it.

Another sign to look for when there’s snow on the ground is little flecks of yellow in the snow: bee poop. Bees do not poop inside their hive unless they are sick or it stays very cold for a really long time and they just can’t get out.

The snow also seems to melt a little faster right on the entrance board when the bees are doing well. Other than that, you can’t tell much unless you get a really warm day and are able to take a peek inside, or at least see bees flying around the entrance. But for most of the winter, the bees will be hidden inside their hive, clustered together around the queen, vibrating their flight muscles to generate heat, and eating the honey they stored away during the summer. And then, at some point, usually around mid February here (if not even earlier), the queen will start laying eggs and the bees will have to raise the temperature inside the cluster (to above 90˚F) because the larvae need it extra warm to survive.
