(Cross post from Irish List) Hi all, I have just returned from an evening at my local bee club where we were attempting to milk semen from drones with a view to some AI work. The drones were all flyers but every one proved to be dry. We were scratching our heads when someone said that they had heard that Bayvarol varroa treatment in the Spring can cause this symptom and indeed these donor hives had been so treated. Has anyone out there had similar experience with Bayvarol/Apistan treatments? If there is anything in this suspicion then Spring treatments should be avoided if not absolutely necessary.
