Treatment for Mites..?

When do you know your done with the mite problem? to stop the treatment?
I mean theres no little bugs but the eggs and all that.
Can you see them on the snake?

I clean the tank, use newspaper for substrate for now and clean it out daily, spray everything with mite off.
Bath the snake every day, soak the body with mite off.
But I dont see anythin on her, just curious as to how long I should keep goin so that its definately stopped..

Doesnt say when to stop, just what to do.
I think they are gone, but then again this is the first time ive treated mites.
Aw well im headed to where I bought her from I can ask the guy I got em from
he seems to know a bit about them
