... And I don't know what ACT is.
I've killed RA and spider mites in a warehouse. There's got to be something that can be done. I have maintained a sterile grow room for over 7 years with no pests until I started bringing clones in. If I find something that kills em I can eliminate. Unfortunately at this rate these things will be alive long after the cockroach.
