I have two brood-less colonies, parent halves of AS, where the the queens might have just been mated but they are not laying yet. Is a quick vape a good idea?
i tried this in spring and it did nothing at all. gave 4 treatments on a 5 day interval and no change in mite drop. i guess it has something to do with bees not clustering. others in the club have reported good results. please try and report mite drop on here!
