Get you a temp/humidity gauge and put it inside the tank. Try to keep it at 55 percent humidity. I have had my snakes go above that but dont let it stay there for along time. A couple days of high humidity has been fine for my snakes. If it stays than you need to rethink your habitat. Can you post a pic of your entire enclosure? I want to see what it looks like at the top. What do you have covering it? What kind of room do you have your snake in? How are you keeping the humidity? Are you running a humidifier? Or is the room just always humid? You might need a dehumidifier for the room. I have a weeping foundation so I have to have a dehumifier or else I would get sick. You got to remember about your health and the snakes health. If your living in a room above 55% humidity you can get mold problems and thats not good for your health or the snakes.
