Can anyone answer if alternating medicines works any better than serially
exhausting the use of one followed by another? If not all of the mites are
killed by applying a medication and some mites survive and give rise to the
strains of resistant mites, how does alternating medications help. Help me
with the arithmetic. It would seem that if two meds are both, say, 99%
effective then the order of treating for mites would not matter, serial or
alternating treatments.
