Did my final inspection of the year yesterday, both of my hives are double deep, and the top deeps are 95% full of honey, plenty for the winter. I did a 24hr sticky board mite drop test, and counted 25 on one hive, and about 12 on the other. The counts are low enough that I'm thinking no treatment is really necessary at all, but I can throw some powdered sugar in there to increase the drop during this brood break if that's a worthwhile thing to do. They're all set for winter and they get really quite testy when I open them up so if it's ok to just leave them alone for a while I will. I'd really like to avoid using any chemical mite treatments if I can avoid it.
