My understanding  was that drizzling was a one time treatment, to avoid
side effects(from the Swiss study)while the vaporizing could be done more
than once ,if  necessary,as it didnt seem to show the side effects (weaker
spring populations).Please correct me if I have the wrong impression.I am
sure that drizzling goes fast enough,but is vaporizing safer for the bees?
