When I received an email from Kelly McLachlin explaining that she had an established colony of honeybees living in a Beech tree in her backyard, I was obviously very intrigued. I had her send me pictures of the tree and the bees and I was still slightly confused. I knew how much hollow space honeybees needed to make their hive and it was perplexing to see them coming and going from a crack in a seemingly solid and healthy tree. When I arrived on site however, things started to become clearer.

The Trap-Out

Another beekeeper, Marco, and I set out to extract this colony without harming the bees or the tree. Kelly was very accommodating and we decided to try a “trap-out”. This method of honeybee extraction includes setting up a bee escape to allow foraging bees to leave the hive, but not return afterwards. To coax them into a new hive, young brood is used to lure the worker bees inside. If all goes well, the bees will raise a new queen from one of the eggs inside the new hive.

This trap-out process can take up to six weeks before the bees have all left the original tree, and it’s very likely that the original queen will never leave. She will die in her empty palace filled with honey. After the extraction, the tree will need to be sealed up completely, otherwise the homeowner stands a very good chance that a new honeybee colony will move right in next year.

Top bar hive with cedar roof

Last weekend, I installed my first top bar hive. I have been planning and building the hive for a couple months so I was excited to move a recently captured swarm into this hive and see how they do. Unfortunately, things didn’t go as smoothly as I’d planned. I’ve included lots of pictures here to show off my hive, and then I’ll describe what happened.

My top bar hive

The roof of my hive was made with a bundle of cedar shingles that cost about $10 at my local lumber store. I made a ridge cap out of some old aluminum that I had lying around.

I decided to build a window on my hive so that I can open it up and see the bees without disrupting the colony. I built the window out of thick glass instead of plexiglas because it won’t warp in the heat and is much more natural of a product than plastic to have inside the hive.

Most of the hive was built using 1″ x 12″ pine material but the follower boards were made from plywood. The design roughly follows Phil Chandler’s top bar hive design, available for free. I also included a screened bottom on the hive using #8 screen that has 1/8″ openings.

As an added bonus on my screened bottom, I constructed a second bottom that sits roughly 1″ below the screen and has a removable tray that pulls out easily to discard Varroa and other debris from the hive.

The entrance to the hive is a 1¼” hole that I drilled while I was on-site, after the hive was situated and set up properly. The bees had no problem finding and using this entrance immediately.

I used some small flagstones to keep the legs of the hive off the ground.

Disaster strikes

After setting up my top bar hive, I started moving bars of drawn comb from my top bar swarm trap to the full size hive. The first few bars were perfectly drawn and completely straight, but by about the 7th bar, I noticed that the drawn comb was beginning to curve a tiny bit off the bars. By the 11th bar, the comb started on one bar and then curved onto the adjacent bar, making it nearly impossible to pull out the bars cleanly, without ruining comb.

I initially solved this problem by simply separating the part of the comb that was curved from the bar, and then gently placing it in the hive, ensuring that the wax was straight under the bar. I had to trim more and more of the comb off the bar, and finally by the 14th bar, I had trimmed too much. The entire drawn comb of capped brood fell off into the hive! Oh no! Then as I was packing up the hive, two more combs fell off. And as I was trying to repair those, a fourth comb fell off! Complete disaster!

Fallen comb in a top bar hive

It was at this point that I took a breather, stepped away from the hive and tried to determine the best course of action. I had 4 fallen combs with brood and a lot of angry bees circling me. I didn’t have any tools to successfully repair the comb but I remembered a tip that I had just learned in my current beekeeping read. You can move fallen comb to the back of the top bar hive, separated by sticks to leave room for brood to hatch. After the brood hatches, you can remove the old wax. So that’s exactly what I did:

Comb separated with sticks

My first ever top bar hive installation could have gone a lot smoother, and I’m not sure if there was a better way to deal with the cross-combing within the hive. I’ve since researched some better solutions for preventing cross-comb in the first place, which I will be certain to start implementing right away. I’ve also read of ways to try and repair comb that falls off like this, so I may be adding a few more tools to my beekeeping kit for future visits.

This is counted as a strike against top bar beekeeping in my opinion. This was one of the harder things I’ve ever had to deal with while beekeeping. If this was my first time ever handling bees, it would have been overwhelming. But I walk away with another notch on my belt and I’m glad that I experienced this. I’ll now be better prepared for the future.


Not less than a day after putting my swarm trap up on my upstairs balcony, I got an email from someone who had a honeybee swarm in a tree in their backyard. Free bees are free bees in my opinion, so we jumped in the car to go get them with my top bar hive swarm trap.

There was a nice swarm of honeybees up in a tree and it was quite easy to shake them into the open box. I captured the whole thing on video, so enjoy!

More updates to follow… Here’s my update post.

Do you have a swarm?

If you suspect that you have a swarm of honeybees, please read my swarm page for more info and to contact me.



I recently built a swarm trap (AKA bait hive) to attract and capture honeybees in my own backyard. The above video shows the finished bait hive, which was based off a standard top bar hive design. I used the tips that I posted previously in my article How to Catch a Swarm of Bees while building this trap.

There are 17 top bars across the top, each with a groove filled with beeswax. The interior volume of the trap is exactly 40 litres and I rubbed lemongrass oil inside as well. I have since placed this trap, with attached cover, on my 2nd-floor balcony. I hope that a swarm of bees will find this to be an ideal location to live and move in.

To be continued… (I hope)

If you’re a beekeeper, you may notice that your bees bring in a rainbow of coloured pollen every day. When they store it in their cells as bee bread, you’ll see many different colours on the comb.

Have you ever wondered what flowers the bees are gathering this pollen from? Well thanks to the folks at Sheffield Beekeepers’ Association, you can now get a relatively good idea about what floral sources your bees are foraging from.

Check out the Interactive Pollen Chart over at the SBA web site. It’s a nifty little tool that gives you some idea of the different colours of pollen from many floral sources. You can even use the season toggle switches at the bottom of the screen to narrow down the seasonal forage.

Note: I realize that many of these flower sources are specific to the UK, but it was too cool not to share this.
