I had a mite problem after I got my Bumblebee from a chain pet store.
I tried Dawn dish soap as I’ve seen in videos on YouTube. They kept popping up even after the Bumblebee was free of mites. They can and will travel from one side of a room to the other in a matter of days.
I removed all substrate from my entire collection and put everyone on paper towels sprayed with Provent-A-Mite spray.
After using the spray twice (a week apart) , no more mites.
Here’s the link where I bought it from.

Spray the paper towel and let it dry before putting it in the enclosure.
Provent-A-Mite can also be used to wipe down everything in your snake room.
