I'm in E Pennsylvania, it's warming up some and my bees are more active. I checked on them today- saw a few mites on the sticky board. I plan to use formic acid strips as well as oxalic vaporizer again this season
Question: should I treat w oxalic now while there's little brood? wasn't sure if it's not a good idea to stress the colony as they're just coming out of winter, but then again the mites will likely stress them more..
