Permethrin will remain effective at killing the mites even when dried and it can be sprayed on the tubs, hides, rack, carpet, etc. You can also spray the paper you use as substrate with it, just make sure it dries completely before putting your snake back on it. I would also keep a supply of treated and dried paper on-hand to use so that you can replace the soiled paper with it when your snake makes a mess.
Thank you! Also, that's a really good idea about keeping treated paper.
