There have been reports that Apistan was "re-formulated" and the 
current fluvalinate is a different version than the original, much 
more potent. Problem is, I have that second hand so it might be or 
might not be true. Anyone know for sure?

If you go to the USDA pesticide sheets, there are different versions 
of fluvalinate which have different lethality. When you are dealing 
with a chemical that kills bugs and not the host bug based on 
concentration, any change could be a problem.
