lol ya ccm its pretty weird! if you only have a couple of piggs who need treatment then using "Revolution" a cat/dog flea and tick treatment is usually the cheapest way. And easier, and you can locate it easier too. Revolution has the same main ingrediant as Ivermectin, Selamectin.So it will kill mites. I can pick up a kitten/cat Revolution tube for $10 which is cheaper and easier than buying Ivermectin.
Dosage(the same as Advantage, which will kill lice)
0.05 cc for a pig 1lb and under
0.1 cc for a 1lb-2lb pig
0.15 cc for a 2lb-3lb
Given orally behind ear.
You can find revolution usually at a vet or basically any where these days. And usually most places will sell one dose to you.
