My Flir thermal imaging camera is a finicky piece of gear that never consistently produces a readable or useful thermal image of my beehives or, more specially, the cluster of bees living in the hives.
I often post items to my beekeeping Facebook page that I don’t post here on my blog, which is generally reserved for content I create myself. For the stuff I had nothing to do with but still piques my beekeeping interests, the Mud Songs Beekeeping Facebook page is the place.Â For instance, here’s my latest Facebook post that talks about how pollen patties can help maintain the brood nest when the weather turns to junk:
So it’s looks like the hive pillow is doing its job. Moisture is rising up through the inner cover hole, passing through the wood chips, condensing on the cold top cover, dripping down on the top of the pillow, where it then evaporates through the holes in the ventilation rim. Hence, the bees inside are kept dry.
A thermal imaging video I posted yesterday shows where my bees are clustering inside their hives, more or less. The video was created by combining high-resolution footage from my cheap cell phone camera with low-resolution footage from my expensive Flir One For Android thermal imaging device. But I also have one of these nice and cheap devices advertised as: “Infrared Thermometer Laser Industrial Temperature Gun Non-Contact with Backlight -50-380Â°Cï¼ˆNOT for Humans).”
I wanted to see if the laser gun — which is about 25 times cheaper than the cheapest Flir One device — might work just as well as a thermal imaging device. Yeah, I know it won’t work as well, per se, but is it good enough for my backyard beekeeping brethren on a budget? I’ll tell you right now, the answer is maybe. Maybe even probably.
Let’s check out my hives with a thermal imaging camera:
Someone on a social media site asked about a non-intrusive way to check on the bees in the winter other than blowing through the entrance or tapping on the hives to see if it riles up the bees. Someone else answered: “Put your phone in the entrance and record the sound. Then you can play it back and turn up the volume. I’ve tried it in the past and could hear their buzzing.” So I gave it a go. Does it work? Well… maybe, maybe not. But I did learn something today.
Some people have noticed that most of my hive boxes are painted black and have asked, “What are you, nuts?”
I would have asked the same thing a few years back. But then I moved to Flatrock, Isle of Newfoundland, where I can see the North Atlantic Ocean from my house, and it’s freezing here.
Someday I’ll start posting instructional beekeeping videos again, but these days I enjoy down and dirty beekeeping work more, just hanging out with the bees and talking out loud, saying whatever comes to mind. I did this a couple days ago while inspecting all seven hives in my little shaded beeyard. Most of it was junk, what I said and what I got on video, but I still think there’s something to be had from watching these kinds of videos where not much happens, because real life, real beekeeping, is exactly that 95% of the time. It’s grimy tedious work. Let’s see what happens…
Subtitled: Checking on Bees That Were Buried in Snow For More Than a Month
I still haven’t posted a video of the big storm from January 17th, 2020, that buried most of my hives, but it’s coming. It’s a spectacle, not really a beekeeping video.
In the meantime, I’ve put together two videos of the same thing — a 7-minute video for people who just want to see the bees and not hear me babble on about stuff, and the 25-minute unabridged version of the first inspections I did with these hives since they got snowed in over a month ago. It’s longer than the typical killing-time-at-work video, but it may be worth a look for new beekeepers who want to get into the nitty-gritty of winter beekeeping. I cover a lot on ground in this one. (Watching it in segments and coming back to it throughout the day might be the best bet.) It’s interesting how snowshoes have become standard beekeeping gear for me since the storm. And by interesting I mean annoying.
Here’s the highlights reel:
Some of you may have heard that the eastern part of the isle of Newfoundland where I keep bees got dinged with a massive snowstorm on January 17th, 2020. The official forecast called for about 90cm (3 feet) of snow. But with winds hitting about 120km/h (75mph), more than a few snowdrifts were taller than me.
The city of St. John’s and surrounding municipalities were under a State of Emergency for about a week. Everything was shut down. I couldn’t check on some of my hives until the roads were passable nine days later. This is what I found when I checked on them:
This is the shortest video I’ve ever posted (about 23 seconds long). It shows what most of my hives look like now (on December 10th) when I pop the tops off and look inside. They’ve been like this for a few weeks now.
Here’s another one of my behind-the-scenes videos. It’s 13 minutes long. Most of it, if not all of it, was shot on my cell phone. This is the stuff I normally throw away, but some people have expressed an appreciation for this kind of thing, just uneventful everyday beekeeping activities. I’m pretty sure these kinds of videos are contributing to the lack of interest shown in my blog lately. Which is fine. I like this quiet time.
Despite the colony in this video being pitifully weak, it did seem to bounce back a bit about 10 days after the inspection shown in the video. Here’s a photo from a hive inspection I did on May 19th, 2018:
Postscript: Yup, the video has some typos in it. That happens sometimes when I rush to get something together over my lunch hour at work. I’ll fix it later.
I usually add just-in-case sugar above the top bars in my hives around early November. By that time — in my local climate — it’s usually so cold that the bees move to the bottom of the hive beneath their honey stores (and then gradually eat their way towards the top of the hive throughout the winter), which makes it easy for me to put the sugar in without bothering them. But that didn’t happen so much this year because November has been unusually warm. Only in the past few days have I noticed the bees, at least in some of the hives, clustering below the top bars. So I decided to add some sugar bricks today…
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.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.
The following is probably the most detailed video of a hive inspection that I’ve posted since the dawn of Mud Songs. For everyone who couldn’t attend the informal beekeeping workshop I had planned to put on today, this video shows what you missed (or would have missed if I’d gone ahead with the workshop). It’s a 24-minute video, which is longer than my usual videos because I left in the all the parts with me yammering on about what I’m doing — exactly the kind of yammering I’d do if I was giving a workshop.
As of today, I’m beginning to reconsider how I do my first hive inspection of the year. I like to reverse the hive (i.e., move the brood nest to the bottom), but next year if I find all the bees are contained in a single deep (which is often the case), instead of moving the bees to the bottom and putting another deep on top, I might move the bees to the bottom and leave the hive like that — as a single-deep hive. It shouldn’t be a problem as long as the bees have enough honey and the queen has some room to lay.
Bees that are confined to a smaller space supposedly work that space faster and better than they would if there was more space (e.g., if there was a full deep on top of them). Apparently, this is common knowledge for beekeepers who always have nucs on hand. The colonies in their nucs tend to build up quicker than those housed in full-sized deeps and hives.
I say it’s common knowledge, but it’s not something I’ve had any experience with until today, sort of, possibly. A brood nest of a colony that I reduced to a single deep a few weeks ago (instead of reversing it) is expanding at least twice as fast as the brood nest in my other colonies that were reversed. It could just mean I have a better queen in the single-deep colony. Or! Maybe the bees in that single-deep hive did better because they were able to concentrate on the limited space they had instead of spreading out their efforts across twice as much space.
I don’t know. But next year when I do my first hive inspection of the year, instead of reversing the hive, if the bees are in a single deep, I’ll reduce the hive to that single deep until the brood nest is ready to expand into a second deep.
March 2019 Postscript: This is pretty much what I do all the time now. If the bees are contained in a single deep during the first hive inspection of the year (sometime in April if I’m lucky) and I don’t see bees on all 10 frames yet, I’ll toss the second (or even third) deep and let the bees expand into that single deep before I add a second deep.
I’ve overheard many conversations about this, not with local beekeepers but online where I continue to tap into the knowledge and experience of some of the world’s best beekeepers. Some of the phrases overheard in these conversations include, “You don’t want to demoralize the bees by giving them too much to work on,” or “Small colonies do better is small hives and big colonies do better in big hives.”
Like I said, that’s pretty much how I play it these days. A colony with only 3 or 4 frames of bees seems to build up faster when it only has 6 or 7 extra frames to work on instead of 16 or 17 frames. It seems to make sense when I stop and think about it.
For any first-year beekeepers in Newfoundland (or a similar climate) wondering what they might find during their first hive inspection of the year (which usually falls somewhere between late April and mid-May), here’s a video of my first hive inspection in 2011 that shows a fairly healthy colony coming out of winter, one that allowed me to steal a boat load of honey from it later that summer (though I may have had to feed it for a few weeks to give it a boost; I don’t remember).
I found honey on the outside frames, some pollen mixed in and then capped and open brood spread out over five or six frames in the middle. I might have been concerned with one or two frames of brood (though queenright colonies with zero brood as late as May 15th isn’t unheard of) but five or six frames of brood during the first week of May is pretty good for my local climate. (None of my colonies are doing as well this year. They’re still recovering from The Attack of The Shrews.) The hive body underneath was more or less empty.
These days I’m usually much faster with my inspections, but overall the video demonstrates how I still inspect (and reverse) my hives every spring. I have a more detailed video in the works, but for now I’ll break it down like this (assuming we’re dealing with a 2-deep Langstroth hive and it’s a warm, windless sunny day somewhere between 11am and 2pm):
I have a colony of bees that always clusters on the west side of their hive — and I don’t know why.I’ve had this colony for almost four years now (she’s an old queen that I started from a swarm cell) and I’ve noticed this clustering behaviour since day one. Even when I rearrange the frames of the brood nest in the spring so all the brood is in the middle of the hive, the brood nest eventually shifts to the west side of the hive.
I’ve checked everything over the years and there’s nothing unusual about the hive set up. No signs of mice, no leaks on one side of the hive, nothing. I’ve used various hive bodies and other hive components. I even moved the hive to a different beeyard and rotated it so the cluster was on the east side. Within a month the cluster shifted to the west side. My best guess is the bees prefer the heat of the setting sun.
July 2019 Postscript: There’s nothing unusual about the bees favouring the warmer or sunny side of their hive. I’ve seen in many times, both in the winter and the summer.
July 2019 Introduction: I don’t add dry sugar to my hives like this anymore. I use sugar bricks instead. However, I’d probably follow this method if I couldn’t use sugar bricks.
I usually pour dry sugar over newspaper into my Langstroth honey bee hives so the bees have something to eat just in case they run out of honey during the winter. Some people refer to it as the Mountain Camp Method, but I’m00 pretty sure beekeepers have been pouring dry sugar into their hives long before Mr Camp came along and popularized it. I’ll call it Dry Sugar Feeding for now on. In any case, it may not be the best method for feeding bees over the winter, but it works well for me and that’s what matters most. I like it because it’s the easiest method I’ve ever tried and it may be better for the bees than hard candy or candy boards. Do a little research on Hydroxymethylfurfural and you’ll know what I’m talking about.
When I first fed my bees dry sugar, I waited until January or February when the bees, if they were low on honey, would cover most of the top bars in the hive. But waiting that long is a pain in the butt for all kinds of reasons, so now I put the sugar in long before the bees really need it — just like I did today. Here’s an 11-minute video recorded a few hours ago that demonstrates the dry sugar method in all its glory. I also explain near the end how moisture quilts work.
P.S.: I’m not a big fan of feeding the bees pollen patties early in the winter because most of the time they don’t need it and it’s not always good to give the bees solids when they can’t get outside for cleansing flights. I try to reserve pollen patties for small colonies that could use a little boost in brood production. The colony in the video that I refer to as being about the size of a human head will get a pollen patty in a week or two. A small cluster like that, which is likely to get smaller before it gets bigger, won’t be able to stay warm much longer. The colony could be in trouble if I can’t get the queen laying soon.
Another postscript (written in part as a response to the first comment): If I had to do this again, I would place something round in the middle of the newspaper, a small bowl or a jar perhaps. Then after I poured the sugar on, Iâ€™d remove the bowl or jar so that a round sugar-free area of newspaper was left behind. Then Iâ€™d cut a hole in the exposed newspaper so that when the cluster came up, the bees would go through the hole without having to chew through the newspaper to get at the sugar. The hole would also allow moisture from the cluster to rise directly up to the moisture quilt. (If I have a chance, I’ll record a follow-up video.)
January 12th, 2016: I eventually cleared a hole in the dry sugar.
