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.
