I am a big fan of Provent-A-Mite, it is awsome for mite problems. I have tried basically every mite product you can find on the pet store shelves and though some do seem to supress the mite problem none of them really fixed the problem until I tried PAM. DON'T USE on your babies but any snake that is well established SHOULD be fine.
For and existing mite problem Remove your snake from its encloser
and put it in a container to soak with a lid ( Don't make the water deeper than the body of the snake, you don't want to drown them not probable but I guess possible)
While it soaks take all your bedding out of the encloser and get rid of it ( Get it out of your House )
Clean the encloser with a diluted bleach mix ( Cap full of bleach to gallon of Hot water )
Do same with any Cage Furniture
unless it is Oven safe (no plastic) then you could Bake it on high heat for several minutes and kill everything hiding in it.
Let Dry
Spray down inside and out side of encloser with PAM let dry 30 min.
Put Fresh Bedding in it and spray very lightly with PAM and let dry
Dry Off your snake ( This removes any drown mites still stuck to it)
Replace in cage.
Make sure to Clean the Water Bowl That is where I found alot of mites hiding Underneath and under the rim ( I run mine through the Dish washer on High heat)
Don't put the bowl back in the enclosure until the PAM has dried then give your snake some fresh water.
This Is what I Have done and have not had any Issues now in almost 2 years. I do use PAM as preventative. I spray down my racks and even the Door seal and window seals to my snake room that way they don't find there way in on there own ( I don't know if that really helps but it doesn't hurt...LOL )
GOOD LUCK... It happens to us all at one time or another.
