Our two hives have been wrapped since November 21st, 2010. That’s about 50 days. We had a little snow near the end of November, but it’s been mild and damp ever since with temperatures averaging between -5° and 5°C (23 to 41°F). Then we got hit with about 40cm (or 16 inches) of wet snow last night. I doubt the bees have consumed much of their honey stores with those mild average temperatures, but I’ve been concerned about the moisture inside the hives. It’s been an exceptionally soggy winter so far.
It’s still too cold to inspect the hives, but blowing into the top entrances provides a simple way to see if the bees are still alive, and it doesn’t bother the whole colony. If all is well, only a few guard bees will buzz up to the top entrance to scare away my bad breath. Here’s the video:
A few guard bees don’t guarantee the whole colony is alive and well, but I’m going to take it as a good sign. All the snow is likely to melt within a week. After that, I’ll lift the hives to check their weight. If they’re light, I might have to give them some candy boards or paddies. If they’re still heavy with honey stores, I’ll leave them alone until mid-February. I’ll probably feed them some pollen paddies by March no matter what. We’ll see.
UPDATE (Jan. 18/11): It’s probably better to simply shine a flash light in the top entrance instead of blowing in it. Unless of course the cluster is in the bottom brood chamber. Then I guess blowing is more affective.
