I think we can all benefit from this thread. As a former licensed pesticide applicator, I'm well aware that the pests evolve much faster than the pesticides do. That means one needs to change up what you use before the beasties become immune to it. Outside the orchid shack, I rarely use anything but BT, because I don't want to kill the beneficials. So I am willing to try any home remedies that will work. Soft scale has been my worst problem with the orchids...until this year.
This my Laelia Pacavia and a vanda that have been ravaged in the last week, and I'm open to any suggestions as to who done it, and how to stop it.
