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. Continue reading →
It was zero degree Celsius today (also known as the temperature at which water freezes). It was also extremely damp and miserable. Not a bad day to see if visual inspections of the clusters match the thermal images from my Flir One for Android camera device. Not a bad day to make some pre-winter adjustments to some of my hives too.
Hive #1. Other than dropping in some sugar over the top bars in a week or two, and maybe wrapping the hive, Hive #1 is just the way I like it.
Bottom to top: Solid bottom board; 6mm / quarter-inch shrew-proofing mesh; 2 deeps; rim with entrance hole meshed in; moisture quilt full of wood chips; a piece of scrap plywood / top cover. (Oct. 28, 2016.)
A word about that top cover. Yup, it’s a piece of plywood I found in the corner of my shed. I put something heavy on top to keep it in place, but that’s it. I’ve had it on the hive for several months now, always meaning to replace it with a real top cover but never getting around to it. I may leave it on the hive all winter. Why not? The inside of the hive is warm and dry. Whether it’s a commercially made telescoping top cover dipped in wax with a metal cover, or a dirty piece of scrap plywood taken from a junk heap, it doesn’t seem to make any difference to the bees.
Top cover removed, moisture quilt open. (Oct. 28, 2016.)
From this angle, it looks like the cluster is straddling the deeps.
Today’s the day I removed all the feeders from my hives.
I placed a hive top feeder over a rim on one of my hives about a month ago. I removed the feeder today and found burr comb built up over the top bars, the bees filling in the space I created with the rim.
Burr comb built up over the top bars. (Oct. 23, 2016.)
My best guess is the bees ran out of room for the syrup, so they began building comb above the top bars so they could fill it with syrup. Continue reading →
Here’s a quick video that demonstrates the installation and use of a moisture quilt for winter insulation and ventilation.
All of my moisture quilts are built differently because I’ve never put much planning into building them (I have zero woodworking skills). Some are converted ventilation rims that require a rim underneath, like the one in this video. Others have built in rims as part of the design. Some fit perfectly and create a tight seal on the bottom. Some don’t. And it doesn’t seem to matter either way because they all do a great job at wicking moisture out of the hives and keeping my bees dry all winter.
Moisture quilts, in my experience, aren’t necessary in local climates that aren’t particularly damp and foggy and wet. Smaller colonies that don’t produce much condensation from the bees’ respiration don’t always need extra ventilation or insulation either. A piece of hard insulation over the inner cover often does the trick. Moisture quilts can be a bit scary, too, when it seems like half the colony on warm days attaches itself to the bottom screen of the quilt. But for me the pros outweigh the cons. If dampness is a problem inside any of my hives, I know a moisture quilt will fix it.
Here are some quick snapshots I took this morning of my hives using an infrared camera device attached to my cell phone. It doesn’t provide the most helpful readings at the moment, probably because it’s not cold enough outside to highlight the heat that’s radiating from the insides of the hives. I also used the default settings on the device. More precise calibrations might provide me with better images. But for now, here are my best guesses about what’s happening inside my hives according to these infrared images.
My best guess for this 2-deep hive: the cluster is favouring the top box and there’s a crack between the boxes where heat is escaping. (Oct. 22, 2016.)
I purchased four mated queens in August with the intention of splitting some of my older colonies to create four new colonies. The requeening didn’t work out so well, but eventually I think (I hope) I got one colony started up well from a split and another one requeened. The other two mated queens were killed outright and another replacement queen I picked up a week later isn’t dead, but it’s barely laid an egg and it’s currently living in a nuc box — and it looks like this:
Last year I posted a video of a simple modification I make to hive top feeders that prevents bees from drowning in them. I staple screen over the syrup reservoirs and along the bottom edge inside the reservoirs so there is no way the bees can get into the reservoirs and drown.
If the screen above the reservoirs extended over the entrance area of the feeder (the part where the bees come up to access the syrup, whatever part that’s called), then the bees would also be contained inside the hive. I didn’t have enough screen to do all that recently, but I did add some screen to the entrance area of the feeder so it looks like this:
Hive top feeder with screen stapled over the area where the bees comes up. (Oct. 02, 2016.)
I bought three nucs from the Newfoundland Bee Company in mid-July and today, two and a half months later, each of the subsequent hives are overflowing with bees. Here’s a not-so-great photo I snapped during a marathon beekeeping session that shows what I found in one of them when I opened it today. I even found two frames of capped brood in the top deep of this hive. I’ve never had nuc-hives so full of bees at this time of year before.
A hive packed with bees after reducing it to 2 deeps four days ago. I found 2 frames of capped brood in the top box too. That queen is on fire. (Sept. 30, 2016.)
I have to applaud the Newfoundland Bee Company. The queens that came with their nucs are incredible. I probably could have gotten a honey harvest from these hives if I had thought to super them up. My only concern is that there are too many bees in the hive and they’ll eat through their winter honey stores too fast. I know the cluster will reduce in size by the time November rolls around, but at the moment it would be one seriously gigantic cluster. Continue reading →
