Sounds like a rodent mite and they won't bother the snake at all. they are species specific and won't bite reptiles. They won't be able to reproduce without rodents around either. Just clean the enclosure and everything in it very well. Vacuum and sweep anywhere the rodent may have dropped any of them in your house.. Just because no one wants buggies of any type in their house if they aren't pets that are supposed to be there.
