<p style=”padding-left: 40px;”>When my bun Bam had fur mites (I found him outside, he had mites upon arrival), I treated him, brushed off the skin flakes 2 days after applying the drops, did repeat treatment after 2 weeks, brushed him, and after that I never saw any signs of mites on him again. Sometimes a 3rd and a 4th repeat treatment is needed.</p>
Sometimes, although rarely, you need to switch from Revolution (selamectin) to Ivermectin or Advantage II or plus, because in some areas, fur mites have become resistant to selamectin.
There’s no way you can absolutely be certain that all mites are gone. Vets can do a tape test and microscopy of whatever got caught in the tape glue, but thats not fool proof either. If the number of mites is low, they may just not catch any mites with the tape.
A low nr of mites is as a rule not a problem. Most rabbits carry some fur mites from babyhood, and coexist with them “peacefully”. Problems arise when the rabbit experiences stress (not necessarily severe stress) of some kind. The rabbit’s immune defense is then (temporarily) weakened, and the mites seize the chance to proliferate in a major way.
