I bought male Mojave about 3.5 weeks ago and it did have mites, I used a NIX and water solution (diluted) and sprayed the snake as per the guide, I also treated the other one which I didn't see mites (its a female lesser) and havent seen any at all on her.
The Mojave no longer (after 3 treatments) has any visible mites on him (dead or alive) and I have not seen any little black dots on the paper towel that I am using in his tank either. This is the way it has been for 2 weeks now.
so after 3.5-4 weeks, should it be safe to put him in the rack with my other snakes now?
