I use Ivermectin for our shelter ferrets that have ear mites.

My vet gives me a 3cc syringe with about 2cc of Ivermectin. The
syringe has a needle (but don't use it to penetrate the skin) so that
it makes it easier to get a single drop out. I use one drop in each
ear and that is good for 2 weeks. Then I recheck in 2 weeks, and they
are usually gone. It they aren't, I put in one more drop in each ear.
I've never had to repeat after that.

It's easy and cheap ($1 per cc of Ivermectin). I keep a chart to know
when I've cleaned ears and detected ear mites, then listed the date I
gave the Ivermectin.
