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 →
Here’s a 6-minute video from an inspection I did yesterday that shows me spotting the queen, adding a frame of drawn comb to give the queen more space to lay, and there’s a shot of the bees cleaning up a mouldy frame of pollen taken from one of my dead colonies — and you’ll hear me talking about my plans for inspecting all my hives and how I’m going to manage them. That part sounds boring, but it might give new beekeepers a sense of how to go about inspecting their hives, that is, having a plan and knowing that most plans are a joke. The bees will tell you want they need.
I mention in the video that I plan to add another deep to the hive, which is what I did, though it’s not in the video. It’s in this 1-minute time-lapse behind-the-scenes video where I explain why the hive has a moisture quilt and a few other things.
UPDATE: I’ve since converted all of my fabulously patented ventilation rims into moisture quilts. See the updates at the end for more details.
I made some improvements to the design of my ventilator rim (a.k.a. a ventilation eke). It’s still cheap and easy to make and should do a fine job (I hope) at improving the ventilation of any Langstroth hive. First, I cut four pieces of wood for the front, back and sides of the rim. Here’s a shot of the side pieces:
PREFACE (OCTOBER 08, 2015): I made these insulated inner covers once and didn’t make them again because a piece of insulation over the inner cover in the winter position works just as well and requires no work other than cutting the insulation. I also use moisture quilts instead of hard insulation. See the updates at the bottom of this post for all the details.
The two insulated inner covers with venilation holes / top entrances cut in front. (Oct. 15, 2010.)
Winters in St. John’s, Newfoundland, provide a messy mixture of rain, snow and high winds with irregular periods of freezing and thawing. Wrapping Langstroth honey bee hives with a Type 15 asphalt felt isn’t a bad idea. Neither is installing mouse-proof entrance reducers. Preventing condensation, though, is the top priority. A 1-inch thick piece of R5-rated hard insulation over the inner cover in the winter position will prevent condensation from building up inside the hive during the winter. We used a 1.5-inch thick piece of insulation during our first winter (because we couldn’t find anything else) up until the end of January. Then we had to switch to insulated inner hive covers because the regular inner covers don’t provide enough room for candy cakes and pollen patties. A shim lifting a regular inner cover up an inch or two would provide enough space. However, an all-in-one insulated inner hive cover might be more convenient. It requires moderate carpentry skills (which means we’ll probably go with the shims instead), and it’ll cost a little more, but here’s how we made them if anyone is interested. We’ve tested them, and they work.* Continue reading →
