Still no signs of mites, alive or dead. It seems to have killed them all on day 1, with no resurgence whatsoever. I moved Nim to his new pvc enclosure this week because it had been a month since mite sighting, and I was starting to have trouble keeping temps in the plastic tub. I'll keep an eye out of course, but I think the mites are done. Nim does not seem to have been acutely harmed by the treatment.
