He mentions that that is another way to do it, the problem is you use dry ice to generate the CO2 and he doesn't know where to find that. I imagine that this process is not very simple; of course the dry ice goes on top and the cool carbon dioxide falls, but making sure that it pools and collects and fills the hive requires enclosing the hive from the bottom up which sounds nontrivial when it is that swarmy. I think the bottom is enclosed so one would get those huge things of plastic wrap and wrap around the sides over and over? Similar idea though. And then you would just need to know how long to wait for them to suffocate.

it didn't look like he went through very much effort at all to euthanize with Ajax though.

Some hives have enclosed floors. But modern hives, at least in the UK, now have a mesh floor. Which is there to reduce the numbers of a parasite, varroa. The mesh allows the parasite to fall out of the hive.

It's been a couple years since I kept bees, but it's the same in the US: a mesh floor the better to shed the mites.
