Need to know ways that you get mites....

[Quiet Tempest]

Mites can and do hitchhike on rodents.

They also use people. Any equipment transferred from one enclosure to another can transport them. They can crawl, slowly but for long distances so if one snake has them in a room any snake in that room can also get them.

Do you have mites now or are you just checking?

That's true. When I answered I was thinking about rodent mites (I've had the misfortune of dealing with those before) and that they could be mistaken for reptile mites. It makes my skin crawl just thinking about mites of any variety.
