There is no real way to get rid of it, I'm not sure exactly where you live, but its an established native plant in the hardwood hammock that will just arise in another place if you cut it back in one. The vines that it arises from are probably ancient and themselves the size of small trees. The vine roots as it goes and pops up everywhere. It fruits in late summer, often you won;t see a lot of fruit near the ground, it fruits up in the trees and the animals eat the fruit. Its a main source of food for the native arboreal wildlife.You may see fruit on the ground that was dropped or fell. Most fruit at my place that gets produced nearer the ground also gets cropped off by animals. The best you can do is trim it off the fence at regular intervals IMO.
