I don't think your vet gave you good advice on your mites. More like, "I don't know what I'm doing but I can't let this person know that." advice.

The tank doesn't need any "medicine" to wash it with. Your snake is going to be done a lot of harm and very little good with daily baths. Worst of all, if you subject her to all of this, you are STILL going to have mites!

Please reconsider the advice on treatment you were given. I have had mite outbreaks before, and believe me if one snake is bad, 25 is a nightmare!

What I do is this :

Bag all of the snakes in individual snake bags and put them somewhere safe while I work. Completely empty the tubs, scraping out any bedding if necessary. Wash each tub with soap and hot water and dry them thoroughly. Take the tubs outside on the lawn to finish air drying the cracks and crevices a towel cannot reach. Once the tubs are completely dry, spray a light mist of Provent-a-Mite into each tub. Let the tubs air dry for 30 minutes. I add a layer of bedding to each tub, then spray the bedding lightly with Provent-a-Mite and let dry for 30 minutes.

In the meantime, I spray the racks, walls and floor around the rack for a minimum of 24" around the racks with the PAM and let dry for 30 minutes. If possible, I open a window in the snake room because the stuff is strong and will give you a headache if you breathe it in too long.

Once the rack has dried for 30 minutes, I put the clean, treated tubs back in the rack, minus the hides and water bowls. Those get run through the dishwasher while I'm spraying tubs.

I take each snake out of it's bag and give them a bath. ONE bath. I use room temperature water and a few drops of baby shampoo. I soap each snake like it was me in the shower and rinse each one thoroughly. I dry them gently with a towel, then spray each snake with Reptile Relief spray, wetting each one completely. I put the snake back into the treated tub and leave them to dry. The water dishes and hides go back after 3 hours.

I've only had to take this extreme measure a few times. In between I just use PAM on a monthly basis as a preventative measure.
