Sorry Stoneleighhouse I didn't mean to hijack your thread.
Yes indeed, same goes for me ...
Hachi: CO2 ? - as Derekm says: fire extinguishers and pub gas cylinders.
The problem with fire extinguishers is that the internal delivery tube runs from near the bottom of the cylinder to the exit valve - this is so that liquid CO2 exits through the cylinder valve rather than gas - thus providing the maximum amount of CO2 delivery in the minimum amount of time - which in practice is so fierce that the valve itself (plus any tubing nearby) will instantly be covered in ice as the CO2 turns from liquid to gas. Hence the 'do not hold here' warning labels which should be attached to the delivery horn.
You could use a fire extinguisher by using it in the inverted position, but you'd still need to find some way of controlling the flow - as their valves are on/off types, designed to supply 'all or nothing'.
I use pub gas CO2 for MIG welding, and control the flow using one of those floating-ball regulators normally used for oxygen delivery in hospitals - but even so, I haven't a clue how much CO2 to use. One idea I have is to put some perspex over one of the crown board holes and watch how the bees respond.
So - think I'll do a 2-stage operation: remove the foragers by re-locating the hive, and then dose the remaining bees with a few minutes of CO2, followed by a quick box dismantle - strip the frames away and dump all the bees into a Marburg box funnel to let any remaining foragers fly off, leaving the nurses to enter the box, with the queen remaining outside the Marburg Q/E ready to be squished.
At least that's 'Plan A', as at this morning ...
Stoneleighhouse - good to hear your situation is looking like being under some control again.
