Dr David Heaf is for real ! A true gentleman and scholar .
Yes many of us are finding that the way to go is treatment free . I dont intend to treat either even sugar .
Why ? Well the short
answer is that it does not work unless you define working as paying the producers of these nasty chemicals lots of money for ever .
The long answer is that it does not work as you can see from the % of losses suffered by the conventional beekeepers on a far too regular basis because all you are doing is propping up systems with dynamics that are inherently unstable using what could be called in human terms- drugs .
Bees and verroa are finding a stable relationship in the wild as bees that are not "clean "
enough and verroa that are too vampire like , kill each other . What you will be left with in the wild is tame verroa and clean bees . Fight this and you loose your bees . I would suggest to go with nature .
