I bet if you had dusted them, then put them in a box on white paper towels, covered that box, you would have seen dead lice after 45 minutes. They can and do hide in feather shafts and you can't see them there. But heck, keep on using your ivermectin, and when you need more, I'll sell you an almost full bottle for cheap, lol.Kathy, what do you believe happened to my lice?
And I wasn't using the ivermectin as a wormer.
