Me too. I fitted a Gator blade to mulch them, which does a very good job. The leaves just disappear after a few passes. I used to rake , bag and dump - far too much work!
Sorted through all my boxes, removed any bad frames, treated the good combs with B401 (I still had some left) and put them into winter storage.
Then I rendered the bad comb down with my steam wax-melter.
A satisfying day's work.
The pan warms up from below 100C so the water evaporates slowly. If the OA is put in a hot pan it flash boils and spits.
Your last statement is untrue.
I just fished out my wellies to see if it was one of the brands discussed here (it wasn't) but found a drawing pin stuck through the sole of one of them. So I guess it will leak next time. :(
The pan should be cooled in water between applications. This allows time for the water to boil off before sublimation starts and prevent the spitting. It also removes the possibility of overheating the OA and causing decomposition into formic acid.
... or they all carry the virus but it does not cause problems in all colonies.
David Evans has some thoughts on viruses in the latest BBKA News (Nov 2021).
In my experience they only get moderated when the abused party has the temerity to reply in kind, otherwise the antagonist (usually one of the usual suspects ;)) gets away with it.
I suspect that in the wild, the bees abandon old comb for a while and allow the wax moth to demolish it, before building new comb.
Edit: Ah! Should have read later posts!
