Daniel,
You should try to stop any treatment on at least a few hives. (See : L’Abeille
de France, July-August 1998). There will be withered wings bees during a year
or two but not enough to really weaken the hives. One of my hives has not
received any treatment for three years, the others for two years. It is so much
better not to have to treat in any way.
Best regards.
