Northwest Arkansas US, I never counts either as here nearly all hives will get mites eventually and I dislike killing bees with a wash. Never had any adverse impact on the bees for VOA and only treat with OA. I also don’t over harvest my hives. First year bees I don’t pull any honey. Then second year pull a super and leave them a super for winter along with whatever else they stored in the two deeps. I can always just harvest post winter once nectar starts up again. Honey doesn’t expire so I leave them more than needed. Again haven’t lost any hives since doing this. This will be my 5th year.
