Well, my :2cent: on using Nix versus Provent a Mite is this:
One was designed, tested, marketed and proven for use on reptiles.
One was designed, tested, marketed and proven for use on people.
When it comes to my $5000 collection, I'm not going to take chances and try to save a few bucks. I'm going to use a product I know works and I know is safe.
If you or anyone else wants to run the risk something could go wrong using Nix, that is your choice. I'm not willing to take that chance.
