All this appears to be applications "not according to directions", or
incorrect application and could be assigned to any mite treatment- that
there are repercussions if not used according to directions. The question
is if you do it right, are there issues?
I do use it as a stand-alone treatment and have seen no issues to date. I
listened to our friends in the EU who have been using it many years longer
that us and the only reports i have seen from them is that it is fairly
benign, especially compared to other treatments, and I agree.
