I treated last fall with Apivar, did a powdered sugar shake of 2/3 cup of bees from one hive mostly from one frame of brood comb. I didn't see any from the shake, but while scraping a small amount of drone brood off of a top bar I saw one mite on a larvae. I will probably just continue monitoring the mite level, but if I decide to treat what is an effective method for the spring? I am going to pull the queen and a few frames of brood the first part of May to help prevent swarming and hopefully still get a honey crop. Would that be a good time to use oav? Is oav okay to use during the flow?
Thanks.
