I don’t have a boa yet but I’m assuming mite eradication would be similar to my ball pythons. I just used hot shot no pest strips. My enclosure is 3x2x2 and I cut a quarter size piece into smaller pieces and put them in a little deli cup with a bunch of holes in it. Put it in the enclosures a month ago and no signs of anymore mites. My bigger snake had them worse and he cleared up within 2 days. I didn’t even need to change the substrate. Highly recommend it. Although look into how your snake might take being around the poison. A few species don’t fare too well.
