You didn't say whether or not you also used control nucs without the
treatment, or whether the nucs were made up from Apistan treated mother
colonies.  In the absence of controls, all these observations are simply that:
observations.  The first step in the scientific method, but certainly no basis
for making any kind of conclusion.  If you have no varroa, and your aim is
production rather than science, it is perfectly fine.  Yet such observations
must be verified by controlled scientific experiments by others as well.
