I would just buy some reptile relief and kill the little snotts on contact.I have used ivormectin in the past but prefer reptile relief .Its made by natural chemistry and actualy says reptile spray on the bottle.
Reptile relief is garbage....i've sprayed it on my snakes and still see mites crawling around on them the following day....It doesn't kill anything on contact. I speak from experience.
