I have several Phals, a Psychopsis, a Cymbidium, and a stink bug problem The stinkbugs particularly love my Cym, and I recently discovered that they laid EGGS all over the backs of the petals. I scraped them off with a paper towel, but I keep finding the darn bugs all over my plant! What can I use that will be safe for my orchids but keep those nasty things away?
