When using Ivermectin to treat mites do you use the plain Ivermect or the Ivermect Plus? Injected or orally? At the normal dose for either, or if injected at the label dose? Thanks! My aunt and uncle have a couple of does showing signs of mites....they need to be dosed with Ivermect in case of deerworm anyways. I do not want to go through that again this year!
