I would let it go so long as it not causing any harm. They will die off once there are a few frost. The queen falls to the ground and spends the winter hibernating only to reemerge in the spring to start anew, while the workers simply die. Over winter the nest will break apart and fall to the ground.
If you need to get rid of it and you can reach it I would do as suggest earlier. At night, especially a cold one, put a step ladder under it, climb up with a big garbage back, put it around the nest, tie the bag off and snip the branch. Leather gloves would also be a good idea and remember, this is at your own risk.
Place the nest in the freezer, let it go over night then the next day give it to the chickens, they love it. I did this same thing two years ago with minor instances. Let us know what you do and how it works.
