Here is a tip for your tip. Trying to untangle them is futile! Once they are wrapped up if you tap on their tail with your finger tip it encourages them to slither forward. Guide their head away from the object they are tangled in (so they don't continue to get tangled) and continue touching or tapping their tail.
Yea I don't have experience doing it with other snakes, but my ETB responds really well to this. You can get her off a perch in an instant with a tickle to the tail.
