I STRONGLY suggest that you get in contact with your local Bee-Keepers'
Association. They will be best able to advise on local conditions,
climatic considerations etc. etc.  Chemical treatment for varroa is only
likely to be effective if co-ordinated between local bee-keepers,
otherwise you may increase resistance.
 
Mail me again if you need contacts or addresses.
