Thermal Imaging Beekeeping Hack
This GIF might take a few seconds to load.
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.

Beekeeping on Facebook
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. 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:

Hive Pillow Update
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.

Zapping Beehives With an Infrared Laser Gun Thermometer
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 -50-380°C（NOT for Humans).”
Laser Gun Thermometer.
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.

Thermal Imaging on Beehives
Monitoring a Beehive With a Phone (or Not)
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.

Black Hives
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.

Converting To All-Medium Hives (Sort of)
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…

Winter Beekeeping with a Vengeance
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.
This is what my “beeyard” looked like on January 18th, 2020.
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:

A Rat Gnawing on My Beehive
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.
I’m guessing a rat did this (January 26th, 2020).
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:

Low Winter Clustering
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.

Dry Summer → Less Nectar → More Pollen → More Brood?
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.

How To Inspect a Beehive (or How I Happened to Inspect This Particular Hive on This Particular Day)
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.

Second Thoughts on Reversing
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.
I added the second deep to this hive today, which has more bees than my hives with two deeps. (May 07, 2016.)
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.
How to Do The First Hive Inspection of the Year
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):

A Brood Nest That Favours The West Side
I have a colony of bees that always clusters on the west side of their hive — and I don’t know why.
Cluster expanding from the west side. (April 23, 2016.)
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.
A Real Life Demonstration of Feeding Honey Bees Dry Sugar
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.
2 kg of dry sugar over the top bars.
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, I’d remove the bowl or jar so that a round sugar-free area of newspaper was left behind. Then I’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.
Monitoring Honey Bees with a Stethoscope
I often use a cheap stethoscope to monitor my honey bees in the winter when they’re still clustering below the top bars and out of sight. It’s the least disruptive method I have for checking on the bees.
Listening to the bees with a stethoscope.
It took some practice, but I can tell how deep and how large the cluster is by listening through the hive with the stethoscope. Most of the time, though, I’m just checking that the bees are still alive. That’s usually good enough for me.
A $7 stethoscope.
Sticking my ear against the hive works too, but it’s not as dignified as walking around with a stethoscope.
FEBRUARY 20, 2016: I have to say I continue to be impressed with the $7 stethoscope I bought on Amazon. I listened again to my bees today and could hear a lively buzz of bees in every hive. It takes a bit of imagination to interpret how the bees are doing from the often distant-sounding hum heard through the stethoscope, but at least I can tell they’re still hanging in there.
April 2019 Postscript: I still have my stethoscope, but I don’t use it often anymore. I just bend a knee into the dirt and stick one ear to the side of the hive. I can hear the bees better through my ear.
Switching Out Hard Insulation for Moisture Quilts
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.

Benefits of Frequent Hives Inspections
July 2019 Introduction: I still probably dig into my hives more than I should. My constant curiosity may have made me a pretty good beekeeper when I started, but it’s more likely a liability these days. I should just leave the bees alone most of the time but I don’t.
There are many arguments for and against hands-off beekeeping. For new beekeepers just starting out, for the first year (except for winter), I’d dig into those hives at least once a week. Minimum. Even if it’s just to refill a frame feeder and look down at the bees without pulling out any frames, every chance to stick your face inside a hive is a learning experience. And by you I mean me, because that’s what I did when I started and I know it put me way ahead of the game compared to other beekeepers I know who took a hands-off approach. I know hands-off beekeepers five or six years in who still can’t tell the difference between a queen cup and a drone cell. That’s not good.
I still look in my hives about once a week, but I don’t often dig deep into them. I rarely, if ever, dig into the bottom deep of a hive past the month of May. One thing I don’t do as much as I should is check for swarm cells. I do, but I don’t go crazy with it. I know beekeepers who dig down into the bottom of their hives every seven or eight days after the month of May to check for swarm cells. They see it as standard hive management, and I understand that, and I probably should do it myself, but I really don’t like disturbing the bees that much. I’ll roll the dice and leave the bees alone if I don’t think they’re likely to swarm. In my experience, the colonies that have been the most robust and have made the most honey for me are the ones I was able to leave alone. All summer long they look they could swarm any minute, but they don’t, and they make truck loads of honey for me. People don’t talk about this enough, but managing bees so they come very close to swarming and make tons of honey instead — it’s not easy.
So I guess there’s a time to dig into the hives and a time to leave them alone. Working out that fine balance may be the foundation of good beekeeping.
Hive inspections every two weeks aren’t always such a bad thing, especially for new beekeepers, because one of the best ways to learn what the bees are up to is to see what the bees are up to. (Collect that data!) I found an excuse to dig into my hives at least once a week during my first summer of beekeeping, and I learned more from my intrusiveness and observing everything up close and personal than I ever did from reading or watching the bees from a safe distance. Yes, there is a risk of disturbing the bees and killing the queen, but I was careful and gentle and made sure to put all the frames back the way I found them, and everything worked out fine.
Regular inspections also allowed me to remove comb that would have otherwise gunked up the frames and made future inspections messier. Comb connected between frames will often split open and scrape against honey in adjacent frames and spill honey all over the place. Drone comb, especially between brood boxes, is exceptionally gross when pulled apart.
Regular inspections also allowed me to remove the super glue known as propolis. Frames that are bonded to the hive box with propolis don’t move. It requires careful manoeuvring to pry out the frames with a hive tool — to snap off the propolis — and even then all the extraneous comb between the frames tends to squish bees and tear up honeycomb as well as brood comb along the way. Whereas frames that are cleaned up every two weeks can usually be pulled up with bare hands.
Regular inspections and cleaning up the frames make things less perilous for the queen. Any comb between the frames or the brood boxes can easily trap and kill the queen (along with other bees) while the frames are being pulled out. (Some refer to this as rolling the queen.) Comb between the brood boxes leaves no space for the queen. If the queen is on that comb while a frame is slid back in, she’s dead.
Here’s a photo of a hive that I haven’t touched for almost three months.
Most of the frames are stuck together with wax and propolis after three months of not being touched by humans. (Oct. 12, 2015.)
Those frames are super-glued to the hive box with propolis and are held together by brace-comb as one big solid 10-frame block. Pulling those frames will be one seriously tangly experience (an experience I’m glad to have avoided during my first summer of beekeeping).

What Does Fresh Brood Look Like?
Fresh brood looks like this (click the image for a closer view):
Fresh brood in the upper deep (or hive body). The queen expanding the brood nest up without any help from humans. (August 10, 2015.)
I was planning to pull up a frame or two of brood from the bottom box to make sure the queen expanded the brood nest up (a lazy edition of pyramiding), but I found fresh brood on the second or third frame that I inspected. The queen didn’t need any help from me. So I put everything back the way I found it and left the bees alone.
Pyramiding The Brood Nest
June 2019 Introduction: The original post from 2015 was incredibly long and detailed and I obviously had too much time on my hands. Thanks to social media platforms such as Facebook, Murray, my goldfish, has a greater attention span than most people flicking through their phones these days. It’s not in our bones to slow down and read anything carefully anymore. To hell with poetry! Give me a meme! In that spirit of progress, I present to you a lovely digestible little ditty called, “What is this pyramiding business, anyway?”
This is a hive packed with bees…
Bees crowding all 10 frames. Perfect candidate for pyramiding. (August 2, 2015.)
…so many bees that they’ve run out of space in the hive and it’s time to add another box (i.e., a deep super or a hive body) so the colony has room to grow. But sometimes the queen won’t expand the brood nest into the new box because the workers fill it with honey instead, which can cause the queen to become honey bound (trapped in by honey with nowhere to lay), which can then trigger a swarm, not something most beekeepers want.
A little trick called pyramiding is the solution to that possible problem.

Reversing Brood Boxes, or Not
It’s June 2019 and I’ve significantly rewritten this post from 2014 to reflect my practice of not always reversing the brood boxes in the spring. To cut to the chase, these days I tend to reduce my hives to a single deep in the spring because the colony seems to stay warmer and expand faster when it’s restricted to a single deep. Only when the colony is close to filling the single deep with bees do I add a second deep. If the weather is still cold or the colony is more on the weak side, the second deep goes on the bottom where it’s less likely to screw up the thermodynamics of the brood nest. But if the weather is warm, the colony strong and expanding quickly, the second deep goes on top. You can pretty much skip the rest of this post now.
I used to reverse the brood boxes in my hives in early spring as soon as I had a warm enough day for it. That means at the end of winter in a typical 2-deep hive when the brood nest was usually living only in the top deep, usually some time in April, I would move the top deep (full of bees) to the bottom of the hive and then the bottom deep (mostly empty drawn comb) to the top of the hive.
The logic behind reversing is to prevent swarming by providing space above the brood nest for the colony to expand. That logic assumes honey bees always expand the brood nest upwards. Perhaps the bees have a greater tendency to expand upwards in the spring after a winter of working their way up into their honey stores. But experience tells me that most colonies will expand wherever they can find space, whether it’s up or down or sideways. So the whole argument for reversing is easily dismissed.
Aware of that, I reversed my hives anyway because reversing allowed me to assess the strength of the colony going into the new season and make adjustments on the spot if necessary. I would add drawn comb to the brood nest if the cluster needed the room. I would add frames of honey or pollen if the bees were starving for it. I would give them frames of brood from another colony if they were weak. In short, I would take whatever action was required to get the bees started on the right path for the new season.
Then for the rest of the year, because I knew exactly what condition the colony was in at the beginning of the year, I’d be able to assess the strength of the colony without having to dig much into the hive and disturb the brood nest every time I did an inspection.
