Having a really bad infestation with false spider mites on several orchids in a certain area of my grow tent. I've cleaned up the area and such. I have bought predatory mites, Phytoseiulus persimilis, and I do not see any positive change. I've done weekly releases up to this point, totaling up to over 14k potential mites... making up of different stages. They are alive since I can see the adult ones that are red and are much bigger than false spider mites. I did put in an order for Stethorus punctillum since this species will not directly bother P. persimilis.
