Snakes aren't tree dwellers, BUT many like to climb onto branches for watever reason. Lol, but if you want one though. Make sure it's not any kind of wood that has toxins like Pine. But if it's driftwood or anything like that. Just make sure you clean it and sanitize it. Boil it in water for like 15-20 mins, and bake it in the oven for maybe 30+ mins. You want to make sure there are no parasites or anything that could harm your BP.
