I fed my bees sugar syrup until it was too cold for them to take any more of it, which isn’t always the smartest thing to do because even though the bees are able to store the syrup, they may not have time to cure it (evaporate most of the water from it) and cap it like they would with honey during warmer weather. Subsequently, as in my case, the ole beekeeper discovers a top third deep filled mostly with uncapped syrup — or as we like to say in the real world, moisture. Not enough moisture to drip down on the bees and kill them, but enough to dampen the frames and allow some mold to grow.
I wholeheartedly agree with that beekeeper. He seems like a smart guy.
In a previous post, Moisture Quilts vs Hard Insulation, I argued that hard insulation over the inner cover is a cheap and easy way to keep a hive relatively warm and dry over the winter. And it is. I used hard insulation in my hives for several winters with no problems. Even though I’ve since switched to moisture quilts, this year — as in a couple of weeks ago — I set up two of my five hives with hard insulation as a demonstration that I planned to report in on over the winter. But I pulled the plug on that experiment because I discovered moldy frames in the top boxes of those two hives yesterday.
I’m a true believer in moisture quilts as the best overall ventilation and moisture reduction aid for Langstroth hives in the winter. I’m a true believer because I’ve seen soaking wet hives become dry as a bone within a week of having moisture quilts installed.

Empty moisture quilts are excellent ventilation aids in the high heat of summer too, allowing the bees to regulate the temperature of the brood nest with less fanning and to cure honey sooner. Moisture quilts are also really cheap and easy to make. Everybody wins. Continue reading →
I’m a huge fan of moisture quilts because they keep my bees warm and dry all winter long better than anything I’ve used before. But for my first two winters when I kept my hives in the city in a relatively dry climate, hard insulation over the inner cover worked fine. For people who don’t have much time, money or carpentry skills, the winter preparations I demonstrate in this video are better than nothing.
I’m not saying this is the best winter set up for a hive, but I have a good sense of my local climate and I think this minimal set up will work out okay.
Here’s a photo and text that I’ve copied from a beekeeping journal I maintain for myself. It’s a more detailed entry than I normally bother with, but it’s a summing-up sort of entry, setting the stage for what I’m dealing with going into winter. I’ve also added a few more details for my legion of Mud Songs followers.
1401 (in the back): 3 deeps + a honey super. (All of my honey supers are full of drawn comb, as are most of my deeps.) Approximately year-old naturally mated queen. Good layer and the most docile bees I’ve ever seen. Colony was used to create splits in July. Not likely to get any honey, though I did see nectar in some honey frames the last time I looked. No inner cover. Empty moisture quilt for ventilation. Continue reading →
