Mites- Listen Up!
I used to have a boa that had mites ( he is still alive today I traded for a burm) Everything I tried would not work and I tried for months and months. I came up with a non toxic idea. I cleaned the cage and vacumed the floor every other day and every 24 hours I would cover the snake in a thick layer of non scented soap, I used dove. Do not rinse the soap off put the snake back in the cage with the layer of soap on it. Rinse the snake off in water the next day and apply again. DO NOT LEAVE SOAP ON DURRING FEEDING. I noticed no mites after a few days but I did this treatment all for three weeks to be safe. Its a lot of work but it is sure worth it.
