Ok I know I'm going to get flamed for piston this because it's been talked to death but here goes anyway. We are up to around 35+/- snakes and a couple lizards and we would like to begin monthly preventative cleanings of our tubs with a mite killer.

We have heard a lot of praise for PAM but 1.the way I understand it you can't spray this on your animals and I would think that not spraying your animals would allow a reinfestation of the enclosure if the mites were still on the animal. 2. If this is the stuff to go with where does everyone get a good price?
Next question is what about the stuff RBI sells? I have come to trust Rich and doubt he would sell a crap product but wanted your thoughts on it. I like that I can purchase a gallon of it at a time.
Lastly, who uses Nix and what advice would you have on that?
