You can try digging up the tubers, but if you don't get them all out, they will return. Mowing will not help. You can spray them with an herbicide labeled for their use. Even so, you may need to retreat. The tubers are tough to eradicate. Plus the leaves are waxy and difficult to penetrate. It may be worth hiring a professional to get rid of them.

I couldn't tell where you are by that zone, but here are a couple articles that may help:
