Re: Stores Question
If you plan to use Formic Pro you will want to have a super on each hive during treatment to give the bees space to spread out, per Formic Pro instructions.
Post treatment I would plan on going into winter with double deeps on each hive and the supers off. It will make life a lot easier next spring if you would be doing any spring reversals.
Keep an eye on the stores after your treatment and if necessary feed them 2:1 before it gets too cold. Sounds like they are in good shape right now but monitor closely to make sure they don't burn through a lot of their stores later in the fall.
To everything there is a season....
