I guess I am treatment free. I use IPM and buy resistant stock and graft from those and my best queens to put in to nucs. I haven't treated in 5 years but I am not apposed to "soft chem" treatment if I really needed to but I haven't needed to. So, splitting is my main mite control in the spring and fall. I also steal brood frames for mating nucs throughout the season. In the spring I just split, now in the fall I feel I should only split hives that meet the Economic Threshold. Problem is I am not sure what that is. Any ideas.
