It seems to me that if several different approved, proven, and available
treatments are out there, the best approach would be to develop a rotation
scheme similar to those available for treating worms (fly larvae) in
horses. By alternating between 2 or more treatments, resistance
development would be greatly delayed, since the pests would need to develop
resistance to both forms of treatment at once. Otherwise, those mites (and
their descendents) that survive one type of treatment would likely be wiped
out by the second type.
