| I used neem loi fairly regularly (when it was warranted) to control outbreaks of soft bodied insects like mealy bugs. I used it on Catts, Coel and a few other thick-leaved genera without any adverse results. I had heard it should not be used on thin-leafed orchids like Paphs so i have not done so. It is possible that Neem oil used undercertain growing conditions could be detrimental, as was Cynthia's experience, but this was not the case in my growing conditions.
