I wasn't making an argument. I wouldn't use Nix personally and I had no idea what the ingredient was as well. I was just putting it out there about the mites somewhere in the West are becoming resistant to Permethrin. Hell I use the Reptile Relief thing mostly, though I do spray the QT tubs with Provent a mite.
Also for those ordering Provent a mite it's cheaper to get it directly from them. They've lowered the price to like $15.95 and other places still have it at $17+. Just a heads up.
