It seems that if resistance to amitraz is inevitable, using it doesn't ever
solve the problem. It may postpone it a few years (or maybe decades) in the
hopes that something better comes along that mites won't show resistance
to. If OA and Formic aren't the "something better" and it hasn't come along
since the late 80's, what are the odds it will in the next few years? Isn't
it just an effort in futility?
