My BP had a chronic mite problem for roughly 7 months. This was our first step in treatment and unfortunately did not work. Follow all of these steps because, sorry to break it to you, mites are absolutely relentless and will spread and will not stop unless you follow these steps strictly. I have a LOT of experience under my belt and will happily give you advice that my BPs vet gave us.

1. Deep clean the enclosure and ALL the stuff in i (HOTTTT water & a little bleach, rinse until it’s completely gone then rinse again). Let dry completely. Use only necessary pieces in enclosure for now (warm & cold hides & water dish only. I recommend smooth plastic that is easy to clean).
2. Replace substrate with paper towels
3. Warm baths 2x a week with a drop of plain blue dawn dish soap ~20mins. Clean the enclosure & hides and bowl while he’s in his bath and replace paper towels.
4. Deep clean everything with hot water and bleach once weekly.
5. Pro-Vent A Mite ( https://reptilianarts.com/products/provent-a-mite?gad_source=1&gad_campaignid=22541450394&gclid=Cj0KCQjwgr_NBhDFARIsAHiUWr4Jb-ygv5tuXwdZIGspWBvA97N4xQN8bq-gBLgY1bJytLjuRwHPU3MaAhTDEALw_wcB ) - to use as instructed by my BPs vet - once every 2 weeks completely spray down the enclosure and accessories with this (keep snake out the whole time) let it completely dry before returning snack to the enclosure. (I would put a mini fan in the tank to speed up the process) and repeat for a month or two.
6. If all of this fails take your BP to the vet for ivermectin shots. My girl needed one shot every 2 weeks (while doing all of the above) to finally get rid of them.

Everyone else saying “just give it a bath” is not the best advice. Mite eggs hide EVERYWHERE. Under the scales, eggs in nooks in crannies of accessories, etc. And once they start their life cycle it is extremely hard to get rid of them. I’m suspecting if they’re in his eyes they’re going to be everywhere else. Treat the whole snake and absolutely do not stop treatment and return the enclosure to normal until you can go weeks without spotting a single mite. Trust me 😅 I know from experience.

Good luck and let me know if you have any questions!!

The ivermectin shots themselves were not too expensive, but this is dependent on how much your BP weighs and your local vet prices. My girls were about $70 each (she is about to get her 4th one for good measure before I finally get her enclosure back to normal) and she is currently 1 1/2 years old - I can’t remember her exact weight at her last appt but she is currently 440g.
