Paul - those mite counts are not good!  I just did another round of OAV
today and I still see too much variability in generation of the OAV.  I
agree with you it is satisfying to see OAV coming out of cracks and
crevices but does that equal good distribution?  I prefer to see well
dusted bees emerging from the entrance after vaporization as a good coating
of OA on the bee's body seems to be the way to kill the mites.

I tightened up all my equipment several years ago to better capture formic
fumes so i don't always see vapor exiting after vaporization.  I followed
OAV today with feeding by pumping liquid sugar into 2 gallon division board
feeders and saw lingering OAV inside several feeders fully five minutes
after vaporization.

I am still wondering how to get the proper dose of vapor with the ProVap.
I see tremendous variability in generation of vapor depending on the
temperature of the device and the way the OA crystals drop into the
vaporizing bowl.   Variability is a killer, so I am looking for more
information on getting a consistent dose of vapor in a timely fashion.
