I would think that it would depend on the chemicals being used, but it's just one of those ... I wonder if anyone has ever tried ? I know that some peeps use systemic insecticides, so what's the diff?
I spray regularly (the entire collection) to keep pests from getting a foothold. I do not use foggers, but rather a back pack sprayer that puts out a fine mist that sticks to all sides and surfaces of the orchids. This damages most blooms that are open, but keeps the bugs away.
