An orchid grower shipped me some catts that had mealybugs, and they're spreading to my other catts despite isolation.
I've removed all visible mealies with cotton swabs and alcohol, and sprayed with Bayers Advanced. Yet they keep coming back!
Now I'm suspecting that they are hiding underneath the surface, among the roots and the bark. I need something I can drench the bark/roots with, of course, without hurting the roots. What do you recommend for drenching the pots? I know, the other option is to repot...but it's already almost autumn and I don't want to disturb the roots now because they're stuck fast to the pot.
