What kind of substrate are you using? Snake mites are not white, so I suspect you have some sort of bug that was in the bedding.

PAM (provent-a-mite, LOL!) should still get rid of it.

If it were snake mites, you would not need to worry about yourself or the house; they only want the snake. However, not knowing for sure what these are, I'd recommend treating the snake's enclosure, then keeping a close eye out to see if you see any more anywhere. If you still have more bedding in the bag it came in, look in there to see if you have any.

I use newspaper as a substrate, and this is one of many reasons why I prefer it.
