? OTC Ear Mite Treatment

Does anyone have any experience with success in treating ear mites with an OTC medication? Better yet, a homeopathic remedy? My porch kitty, Blackie, has ear mites even after 3 months of Revolution. In about 2 weeks I will be putting Frontline on her because I just discovered Revolution doesn’t repell ticks (even though it says it should on the box).

 

Where does it say the Revolution for cats is supposed to repel ticks?
