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. …
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.
I noticed yesterday there’s significant gap between the bottom and top deep as well as between the top deep and the inner cover of one of my hives. Here are some photos:
I noticed the crack between the deeps when I first installed the top deep:
Thinking it was the new top deep, I switched it with another one but the same gap (or crack) still appeared. Which leads me to conclude that the top edge of the bottom deep isn’t flat. And who knows what’s happening with the crack beneath the inner cover. The inner cover might be warped. I hope that’s all it is, because that’s one big massive crack.
I’m used to dealing with some cracks between the hive components from time to time. Most of the cracks provide ventilation that doesn’t hurt the bees. But the cracks in this hive are a bit much. I’ll probably fill them in with duct tape once I’m done tearing the hives apart for the year. Completely replacing all the deeps and inner covers with ones that still might not fit tightly together — I can’t be bothered. I have no interest in messing with the bees that much at this time of year.
