I had ridiculous success with Provent-a-Mite when I brought back pests from a local reptile expo. It was a simple as cleaning each tub well, followed by spraying down each tub and waiting overnight for it to dry. It took me a couple days to complete my entire rack.

You NEED to be careful though! Read the directions and be cautious! This stuff will save you a lot of time and effort and frustration (In my thankfully limited experience, it works WELL) but it needs to be used properly. NEVER put it on the snakes. You have to spray the bedding, wait some time for it to dry, and then put the snake back in, and that will actually kill the mites on the snake. It also boasts preventing mites for some weeks after using it.
Take your time, do not rush. This stuff works without the pain of having to freeze everything and scrub everything like twice a day every day for a million years and hoping you got everything.
The trade off is you need to respect the toxicity of the product when wet.
I strongly recommend this product.
The results are noticeable almost instantly -- that means almost instant relief for your snakes. Yes, it really can be that easy!
