As @gina5678 stated, you can find some on Amazon. Use as directed.
Bedding changes do not have to be daily. You can check it for mites and if any are seen, you can change it. But it won’t hurt to change it regularly to keep them away.
I would use the soap until you get the spray. Then just use the spray ad directed. The soap idea is in place of the sprays or inital step to try and get rid of as much as possible.
You definitely want to toss all your substrate and plants. Use paper towels while doing the treatment. The Ivermectin treatment seems to be the most comprehensive as it treats the snake and the enclosure. Provent-A-Mite (PAM) is used by many people with great success. It works even though you don’t use it directly on the snake. Emily says RID has the same active ingredients at a quarter the cost. RID will not have directions on how to use it on snakes, so you would probably look up the directions for PAM and use them with the RID. The snake mite life cycle is about two weeks, so to be safe I would treat for three weeks. Definitely setup the infected snake in a room as far from the rest of your collection as possible. Clean your hands thoroughly after working on the infected snake. You do NOT want the mites to spread to the rest of your collection.
Snake mites, like the flu and the common cold, don’t just happen out of thin air. You “caught” them from somewhere. I’d bet money your newly acquired snake came with mites from the breeder. This is one reason we quarantine.
Good luck and keep us updated.
Here is a video on how to setup a bin. It Also has other info, but it does explain how to make it.
I think its wood mites not snake mites. They look like this
Has anyone ever had wood mites from repti chip before?
I could very well be wrong but I think these are ok? And won’t hurt anything? But also I think you can bake the Reptibark to get rid of them……
Substrate like that can carry mites. Most breeders will get their block, and freeze it for a week (if not more) and then thaw it out before using.
Here’s a link to 2 posts about wood mites. From what I’m reading there, they are white. Have you squashed any to see if blood is visible?
I already threw it away 
i was freaking out
I haven’t seen any at all since i got rid of the substrate but when I squished it before there was no blood
I’m a shredded aspen person myself…….
