Bob, I sure hope that this is not true--if it is, I'll be out of business
soon. I'm talking field bees, not house bees.

I have been repopulating unsterilized deadouts that had N ceranae with no

I have also not observed drenching to kill bees.
I'm with Juanse on this--the most important factor appears to be amount of
active ingred into the colony--not the method of application. And as Jerry
says, to extend the treatment over weeks. See ScientificBeekeeping for
mixing instructions.
I'm also with Bob in that N ceranae does not appear to respond to fumagillin
the same as N apis. Looks like it requires a bit more a.i.
And sometimes it simply does not bring down spore levels, even when applied
multiple times. This is from personal published trial, and feedback from
large commercial beeks.

Bob, are you sure that you are not referring to ProHealth, which was reverse
engineered from HBH?

Sorry to hear, Bob. Sure hope that you keep enough colonies to keep giving
us your valuable observations!
