Depending on how far "over a month" it has been I would start looking closely for new mites. I too tried reptile relief (a few years ago) and found it worked really well for killing the mites crawling on the snake but that was about it. It did NOT kill the eggs in my case and I had to retreat after about 45 days. I now do as Robin describes and use PAM whenever I have a new addition/rescue...and to date haven't seen a mite.Originally Posted by Big Rich
