steady state universe, so no other variables considered.

So started with 300, treated, and you had ten doublings of mite
population every year and each treatment achieved 98% or 99% mite
kill.

This was just a quick and dirty math problem that gave the results of
6 years vrs 10 years for the number of resistant mites to be equal.

In any case, it seems to track just what happened with Apistan.
