Absolutely! I started examining my big Catts very carefully and found a ton of those nasty critters hiding in cracks and under leaves. I'm wiping off what I can with rubbing alcohol and cotton balls and then spraying with Bayer 3 in 1. It takes a lot of time but this is war.
As for the Pleurothallis, we've been getting down into the 50s on some nights and it seems really happy.
