Not sure how you came to view July as the fall. I do not treat until 
November in Maine. Yes it is cold, but OA can be administered down to 
freezing. I extract twice, one in late July early Aug and once in September.

Even things like Apistan have the strips go on after the last super is 
off, usually in September in Maine which means they would be removed in 
November.

I hoped that Ari would step in on your use of OA, but my recollections 
on its use is only one time in the fall and you might get by with two in 
the spring. If you give two in the fall you are asking for disaster 
because you will weaken the bees and they probably will not survive the 
winter. This is an area which I hope Ari will address since he knows 
what is recommended in Europe. Plus, I do not like the vapor method. It 
seems the EU uses the drip method, but again, wait for Ari.
