fumigation in a stack of brood chambers but we are advised by our Bee
Officers it is not necessarily complete in contrast to its effectiveness
with honey comb.

And feeding back honey from EFB contaminated comb!!

The high concentration of fumes would need an enormous quantity of
acetic acid and corrode all your exposed metal.
