My juvenile Spider got mites right before she shed. I talked to the owner of a local shop about my concerns with spraying chemicals, especially during the shedding process. He taught me a little trick that I never heard before, so I gave it a try and it worked great!

Use 1-2 caps of DAWN dish soap (apparently Dawn is the only brand to provide results) and dilute it into 8-10oz of water. Use a spray bottle to spray down the snake in a clean tub. Obviously avoid spraying the snakes head. If you need to treat the neck area, run your fingers gently up the snakes body, pushing the solution towards the neck. After you've treated the snake with the solution, rinse in lukewarm water.

I was skeptical at first, but I was pleasantly surprised with the results. It killed the mites and she shed without any issues. I repeated the process after she shed, treated both snakes' enclosures with PAM and I haven't seen a mite since. Both are currently doing exceptionally well; feeding aggressively and living comfortably.

Hope this helps!
