I usually add just-in-case sugar above the top bars in my hives around early November. By that time — in my local climate — it’s usually so cold that the bees move to the bottom of the hive beneath their honey stores (and then gradually eat their way towards the top of the hive throughout the winter), which makes it easy for me to put the sugar in without bothering them. But that didn’t happen so much this year because November has been unusually warm. Only in the past few days have I noticed the bees, at least in some of the hives, clustering below the top bars. So I decided to add some sugar bricks today…
It was 18°C / 64°F today and the bees in all of my hives — even with shrew-proofing 6mm / quarter-inch mesh covering all the entrances — were out in full force.
I’ve heard arguments that the bees can’t get through quarter-inch mesh. But that’s not true. If it was, my bees would have been locked inside their hives behind the mesh all last winter. The bees in the above photograph wouldn’t be flying around today.
Despite following the Mountain Camp method of dry sugar feeding in the winter more or less since I started beekeeping, I don’t do it anymore. I’ve switched to easy-to-make and easy-to-add sugar cakes.
I don’t use dry sugar anymore because the bees tend to remove it from the hive if they’re not hungry enough to eat it. Spraying the sugar down with water so it hardens helps to prevent this, but if the weather is still warm enough so that the bees are flying around, they’ll do what active bees like to do: clean house. Whatever grains of sugar are not hardened together will often get tossed out of the hive. I used to add dry sugar sometime in November after the temperatures took a serious dip — when the bees were clustered below the top bars, not actively flying around in house-cleaning mode. Overall, the discarded sugar wasn’t a huge problem. If the bees were hungry, they ate the sugar regardless of the weather. But still, sometimes it seemed like a waste of sugar.
I may not wrap all of my hives this year, but I’ve decided to wrap at least the ones that don’t get much sunshine.The black wrap will perhaps warm them up a degree or two on really cold (but sunny) days so they can move more easily onto honey frames. My feelings about wrapping my hives continues to evolve. I began in 2010 by wrapping my hives in roofing felt just like this, except now I use thumb tacks instead of staples because they’re easy to push into the hive and don’t disturb the bees like the bang of a staple gun. (Both this and using push pins to attach shrew-proofing mesh was recommended to me by one of the 6 regular readers of Mud Songs. You know who you are. Thanks.) Over the years, though, mostly due to laziness and the fact that my beehives were an inconvenient distance from where I lived, I got out of the habit of wrapping them and it didn’t seem to make any difference to my over-winter survival rates. Generally, colonies that went into winter in good shape, came out in good shape whether they were wrapped or not.
But last winter, not having wrapped any of my hives, I wasn’t too impressed with how they came out of the winter. None of them died, but neither where they strong. Having hives mostly full of old and stressed queens may explain some of it, but I also noticed in hindsight most of my hives get very little direct sunlight in the winter, much less sunlight than any of my hives in the past. So just to be safe, I’m wrapping the hives that get the least of amount of sunlight. We’ll see what happens.
