I don’t know where my mites originated from, but in a short amount of time, Sniffie, Raisinet and Plinko all had them. What I did seems to have worked, because I haven’t seen them since.
You’ll want two products. Provent a mite and Nix.
First I would take the animal out and soak it in water. While it’s soaking, completely clean out the entire enclosure. Using Provent a Mite, follow the instructions on the can EXACTLY. Let it air dry very well. You want to make sure you don’t smell it at all before you put your animal back in. Whatever substrate you’re using, switch to white paper towels for the time being. Other than a few hides and a water dish, don’t put in any decorations. You want the enclosure as sterile as possible, so the mites have nowhere to hide.
Then, you’ll want to make a Nix solution.
These things helped me get rid of my mites for good. Be very careful with the provent a mite, it’s very powerful. Don’t double up spraying the enclosure with nix and PAM, the nix is just for the animal and any new substrate you’ll be putting in.
Also don’t ever soak your animal in the nix solution, because they could drink it.
You shouldn’t have to reapply the provent a mite, but you might want to keep spritzing with the nix solution if you still see mites after the initial treatment. Just make sure to not get any in the water, etc.
Others can feel free to chime in, but I’m pretty sure that’s how I did it. I also sprayed the Nix all around my apartment and in my carpets so I didn’t have to worry about them hiding. The Nix solution is relatively safe, so I wasn’t really afraid to use it as a preventative measure. The PAM is much stronger, so use it sparingly.
WARNING: If you have a GARTER SNAKE, you should not use provent-a-mite. Some garters seem to be sensitive to it in a way other snakes are not, and garters have died after this product was used, even when following the directions. One person in a forum thread even reported losing a hognose.
There is an alternate application method mentioned in the thread that MIGHT work, but please be aware of the risks regarding this product.
Nix contains the same chemical and might also be unsafe. Again, someone in thread mentions some deaths related to using a lice shampoo, although no name was mentioned.
