I treated with Formic pro in September and the mite count dropped sharply after to almost nil, but still the odd one or two every few days. I just got back from being away for work for 3 weeks and checked the bottom board and wow, a ton of mites on there. At least several dozen. So now what? I have another Formic pro treatment I could do or I can OAV them for a week or so. I fed them about 6 gallons of syrup before I went away and most frames in the honey super were capped but now I notice theyíve burned through most of that, too. Still bringing pollen in on nicer days though itís been quite cool here in Vancouver the last while. Gonna feed again for sure, but I canít feed while doing Formic. Maybe oav while feeding? I donít care about honey now obviously so Iíll leave the box on to feed them. Thoughts?
Ps, bottom deep and medium brood boxes are full of bees, I havenít been in to check for brood since Iíve been back.
