I had written from my perspective of a small hobbyist who only needs 
to treat a few hives..

>I can't imaging ripping them apart in November to treat with OA 
trickle.

Mike, do you assume they are all broodless?  I check every hive for 
broodlessness.  I see variations in hives as to when they go 
broodless.

Opening hives in November may seem a little crazy but the bees take 
it all right and there is no harm.  I am gentle when handling hives 
and do it when temps are in the 40's or 50's F.  

>>I'll know in a few weeks if this is actually working.

Please give feedback then.  I'd be interested in your results.
