Unfortunately, 5 years on, our hive location needed a bit of renovation. The nearby stand of clumping bamboo had decided to make an appearance directly under the hive. It's tough stuff - see how it has raised the bricks, the heavy concrete slab and the hive? That's quite a bit of weight that has been lifted.
The hive was no longer level and action needed to be taken quick smart. Unfortunately there are no other suitable spots in our yard for a hive so we needed to fix its current location.
This meant we had to move the hive elsewhere in the garden for a day while we dealt with the bamboo. Moving a hive is not a small job and in our case we needed to keep the bees contained within the hive for a day, while we worked on fixing the hive location.
I knew we had to keep the hive well ventilated so the bees would survive inside for a day, so I did some thinking and asking around for advice. I decided to use plastic flyscreen to block the entrance and then add a an additional box onto the hive with the top covered in flyscreen for additional ventilation.
Here's how we went about the hive moving process:
Around midday on the day of the planned move I secured the flyscreen to the top of an empty super and put this on top of the hive so that the flyscreen side was directly under the lid.
Then we waited until dark, suited up and taped a piece of flyscreen over the entrance to keep the bees inside. Sounds easy, right? Well not exactly. As soon as I started taping the flyscreen to the entrance the bees started trying to come out. It might have worked better if I'd been using stiff wire flyscreen instead of plastic. The entrance of the hive was almost as wide as the box so it was difficult to tape it on quickly while trying to hold it in place so the bees couldn't pour out. And being dark, Mr PragSust had to hold a torch above so I could see what I was doing ...and of course that light also got the bees active. I started off wearing gloves but they were too cumbersome to be able to manage the tape and scissors so off one glove came. And yes I got stung on the hand but it could have been a lot worse. Some time and a lot of sticky tape later the entrance was closed. Then we had to move the hive. That went surprisingly well and the hive was soon in its new, temporary spot. We hoped that not too many bees came out so that we wouldn't have to suit up to do the garden works tomorrow.
The next day I was pleased to see that the stickytape was still in place and few bees had returned to the old location. I was glad I'd added the extra screened box because the bees were piling up at the entrance and blocking any ventilation in that way.

Because I am a bit sensitive to bee stings, I suited up to do the garden work, but Mr PragSust didn't bother. Our plan was to remove the brick pavers and the edging and dig up the area underneath and remove all the bamboo roots. Then we would dig a trench and put in some root barrier to stop the bamboo roots spreading back towards the hive.
The only root barrier we could get at short notice was 60 cm which was a bit higher than we needed. As we were under a bit of time pressure to get the job done we took what was available as we knew we could trim it back later.

Removing the roots wasn't too much of a drama. I should have taken a photo showing the large amount of root mass we removed, but I was too busy digging. We dug up the whole area, making sure we'd removed all the roots. There were a few bees flying around but they were more confused - as in 'where's my house gone?' - rather than aggressive.
What took most of the time was digging the trench for the root barrier. After our very dry summer the ground was like concrete. We had to use a round fencing bar to break it up. Mr PragSust did the hard work of pounding up and down with the fencing bar while I used the trenching shovel to remove the loosened earth. It took ages to dig the trench. Although the bamboo roots seemed to be fairly shallow, we didn't want to be doing this again so we dug the trench to well below the level of the roots. After much hard work the trench was deep enough to install the root barrier.
The root barrier went in and we back-filled the trench with earth. Mr PragSust went off for a well-deserved break while I finished off the process. I smoothed the earth over the area, replaced the wooden edging and spread woody mulch (obtained for free from the local arborist) over the whole area. We weren't planning to replace the brick pavers even if we did have the time (which we didn't). The concrete paver on which the hive sits was put back in place and leveled with a spirit level. Then the wooden stand for weighing the hive was put back on the paver, raised at the back with a long thin piece of paving stone. All ready for the hive to come back. We carried the hive back and gently placed it on the stand and Mr PragSust knocked off for the day. I removed the top box and replaced the hive mat and lid. Then I gently removed the tape and flyscreen from the entrance. I thought after being cooped up all day the bees would have been pretty agro but I was pleasantly surprised. I quickly moved away from the hive but I wasn't chased. An hour or so later and all was calm again.
Here's the hive back in position:
You can see the black root barrier curving around the corner of the stand of bamboo. We haven't trimmed it down yet.
All in all the whole process went pretty well. The only stings received were the ones to my hand when I was trying to tape up the hive entrance. The work did take most of a day so I was glad we had provided adequate ventilation for the hive. The empty box was definitely required as the bees blocked up the front entrance trying to find a way out. Without the additional ventilation they would most likely have over-heated and we could have lost the hive.
- We need a better way to quickly and securely block the hive entrance while still allowing ventilation. Maybe something like flywire with a framed wooden edge that could be quickly slotted in place with the framed edges flush against the hive, preventing the bees from escaping, and with some quick way of securing it in place.
- Plan as much as you can beforehand for the job and be prepared with all necessary equipment. We really needed the fencing bar and the trenching shovel for this job.
- Things always take longer to do than you think!
