I keep all my exotics (snakes, lizards, tarantulas) in my temperature-controlled office, but unfortunately, recently acquired snake mites. I moved the tarantulas out to my living room and treated my 30+ snakes with Nix dilution (bath, spray), but I would like to move the tarantulas back as my office is kept at 75°F and my house is usually mid-to-high sixties (and I miss my tarantulas). How long should I wait before moving the tarantulas back? I did not spray on the tarantulas' shelf, nor near it, and of course the snakes don't go crawling over the tarantulas. As of right now I appear to be mite-free, but these little jerks are wily and I may have to spray again (if I do, I will remove the tarantulas - again!).
