Wisteria can be extremely invasive unless it is periodically pruned and maintained. Now is an ideal time to prune back to the base of the original plant and dispose of all cuttings. You can attempt to dig the original plant but recognize that many of the feeder roots spread underground laterally and establish their presence on any structure that will provide support. If you want to maintain the plant and appreciate its beautiful flowers then prune aggressively but allow as many desired branches to remain and prune those branches back about three buds from the end.

If you want to eliminate growth completely, then follow the approach listed in the following link which identifies approaches that work and those that don't.

Good luck with your efforts.
