I bought lice-laden roo from an auction, possibly gapeworm, too. I gave him Ivemectrin Pour-On (5 or so drops) and did the lice powder (not DE). He has lots of lice egg clumps, and I cut off a lot. I bathed him (he also smelled intensely of cow or pig poop), then when dry did the Ivemectrin and the powder. Will the powder kill the eggs? What else should I do? He is isolated and I plan to re-treat at 10 days. Do I have to still isolate him after that?
