Keeping 800 hives leaves no time to put oil on top bars. I decided
that I needed to come up with something else.
I went to Builders Square bought a $50 Burgess Portable
Propane Fogger. They use them to fog insecticide. I filled it with
mineral oil (food grade of course), pulled the trigger and like
magic I had Mineral Oil fog. I don't know yet how it will work in my
hives. I will set some aside soon for testing.
I still don't know if oil will be effective as fog. Also I don't
know how long this machine, which was made for insecticide, will continue
to make MO fog. I can only hope that the fog doesn't kill my bees.
I'll find out soon.
