Yes - provent-a-mite is the treatment of choice, but until you get it, you can do a few things . . .
bathing the snake and thoroughly cleaning the cage to remove the mites is something you need to do right away, and repeat until you get the provent-a-mite
there are other treatments that will work, but they require you to do stuff frequently and for weeks to be sure
please understand that as innocuous they may look (just little bugs), they can kill your snake
