They're most likely mites. First, if you have other snakes, then you may want to seperate the sick one from them (preferably in another room). Next, you can search this forum for the witch's brew of cures there are for mites.
To confirm the mites, post some pictures. I garuntee you that someone will come along and say that they are 100% mites.
If you'd read the rest of the thread i.e post #4 you'd have seen that the original poster had done some research and found out what was wrong and what to do!
Also members with experience of mites had already advised the original poster too!
If you have some valuable personal experience about ways of getting rid of mites then post it, if not let the experienced members deal with it.
