If this subject has been discussed on Bee-L already, then apologies but I'm new to this list so any info would be useful. Is there anybody working on, or has knowledge of research into natural products for the control of varroa mites. e.g. any work using neem or azadirachtin for example. Any info would be welcome as would responses from anybody interested in doing this sort of research.
