I'd like to second the lizard notion! I've noticed that they are great for helping keep the soft scale under control in my pool cage. Even my Blc.Chia Lin that had a terrible infestation last fall has recovered, since it has spent the winter out in the garden where the lizards can take care of it.
Also to confirm that when I am at home lavishing attention upon my orchids, they sit there and relax, but when I go away they explode! I have a new spike on my Brassavola 'Big Jim' with 4 buds, and two spikes on Gerberara Snow Ballet!
