LLLReptile also carries it and Reptile Relief. You can get the combo pack shipped for around $30 which includes the PAM.

In a bind, you can give your snake a bit of relief by offering it a warm (cage temp) bath that does not exceed in depth half of the snakes body (going up the snake from its belly to its back). Add in a drop or two of Dawn Dish Soap, allow the snake to soak for roughly an hour. Any mites on the snake should be drowned (mostly). Check under his chin, and around his vent, as these are areas where mites LOVE to hide. Also rinse down the back ever 15 minutes to catch the mites riding out the storm on the back of the snake.

Reptile Relief does this same thing, but it kills mites quicker and gets them more effectively. Cautiion though: It will dehydrate your snakes skin after use. You must hydrate your snake in a bath afterwards. PAM is used on the enclousre and will aid in getting rid of the rest of the buggers.

Mites are harmless to humans, they may "show" on your skin, but they are not doing much except for using you as a body to move from one snake to another. If you have any other snakes in your collection be sure they all get PAM'd (cages that is).

Good luck
