I have had a different experience with buckfast queens.  I run about 750
hives and use buckfast queen cells to requeen with. I  requeen when
there are 10s of 1000s of hives in the area from the north,` I'm from
FLORIDA.   When we move these bees we bunch them in my back yard about
100 feet from my back door.  We bunch 168 at a time there and start
loading them a little before dark  and then let whats left get on the
truck  and then net down after dark. It's real hot down here so if
possible we were no suit. Most of the time we were just a T- shirt a
vail a cap and no gloves. It is unsual for us to get a sting during this
process.  I really think its how you handle your bees not the buckfast
that might be the problem. Of course you do find a very few that do get
teste but I never have found a hive that we could not work.
