The Mite Situation.

So should I spray provent a mite again when I take him out to use the mite killer on him to make sure none have spread?

Take him out and if you want, use the Reptile Relief on him.

Take out everything in the enclosure. Spray the enclosure with Provent-a-Mite. Spray any hides that you will put back in the enclosure with Provent-a-Mite. Let it completely dry. Put some paper towels or newspaper in the enclosure to act as bedding. Put the water bowl and two treated hides in the enclosure. Put the snake in the enclosure.

Thank you. Will do. Furio will be all good in no time I hope. (He's pounding anything put in front of him and gaining weight at an insane rate!)
