WHOOAAA there! We don't know that any "harm" has been done yet.
 
     There can be several reasons for anomalies in efficacy, besides
     tau-fluvalinate resistance in Varroa. Until this has been fully
     investigated, (preferably using the resistance test methodology
     developed by our team in Europe) it is wise to keep an open mind.
 
     I understand that Wellmark International (Sandoz Agro Inc that was) is
     currently investigating these cases with the appropriate experts.
 
I agree with your comments about following label instructions for legalised
[bee] medicines. The threat of resistance is very real and illegal, untested
practices may have negative impact on the industry.

Well said Aaron.
I would like to add (for the laic) that abuse and lack of attention to
the prescribed and much recommended instructions, development of
resistance is one of the problems that we face in the practice of
medicine, be it human or veterinary.  There is nothing that the
practitioner of manufacturer can do to remedy the harm once it is done.
I have long feared that that is precisely the problem with Apistan
strips.  Those of you who have read my file will remember that I
mentioned that I bought a number of hives (severely infested by Varroa
mites) and that treatment with Apistan strips did absolutely nothing to
the mites. (Did the previous owner exceed recommended dosage?)
   Altering the physical characteristics of the strips could be
releasing more than
intended amounts of the pesticide (thus increased efficacy noted).
HOWEVER, that increased amount of the active ingredient is going to be
incorporated to the brood chamber and its contents.  BEWARE of the
consequences! I think that the writing is on the wall!
Best regards.
