Nix on snakes

[a_god_s]

I went to the local pet store for dog food, stopped in to look at the snakes (all on hold because of mites), I didn't touch any and left right away. Now I realize I brought more than dog food home with me that day.

I realized I had a problem when I saw excessive soaking from one, checked him out and Yep, I've got them. Check the others, only two show "dirt" but I know its best to treat them all and the surrounding stuff.
I found a great thread on dealing with those pesky little bugger but I have concerns as the information stated it was used on pythons and boas. Would the concentration of Nix be diluted even more for cornsnakes? Should it be even more diluted for hatchlings?
One more question, is Rid the same as Nix?

Thanks for the help and know I know better!
