Need Advice - Should I try to save this Bellina Splendid X Surprise?

You wouldn't want to introduce predatory mites right after using bifenthrin - it kills the good as well as the bad. I don't know how long you have to wait. I also doubt that using the predatory mites after you have killed off the bad ones as a preventive will be all that effective even if you wait long enough - the good ones need bad ones to eat, and so if they don't have anything to eat they won't stick around, will go off looking for dinner elsewhere (or die).
