It sounds like you need to order some Provent-A-Mite. Mites are very small (little specks) and ticks are much bigger (head usually imbedded into skin and the body gets more swollen as it suck out the blood). A vet can accurately diagnose, but I believe in either case you'll still need that Provent-A-Mite. I know you can get it online, but you may be lucky and be able to find some locally. Good luck. Make sure to treat the snake and the cage. Hygiene very important!!!!
