What would be the best course of treatment? I can't afford to buy elector psp, what I have on hand is Permectrin II, A poultry dust, and Ivermectin. He's been dosed with Ivermectin. And I missed one cycle and went a few days over the 7 day cycle. Last Wed I sprayed him with Permectrin. Treated with Ivermectin. Waited a few days and then dusted him. What do I do, I'm still seeing a few mites here and there. He's been in quarantine for almost a month.
