How can I go about killing mint plants?

Mint needs partial sun and regular watering. If you leave it in shade or direct sunlight and stop watering it, mint will cease to grow.

Dig up these plants and keep their roots as intact as possible. Next, cover the area with black sheets of plastic for 2-4 weeks. This kills the plants underneath.

Pull the plants out by their roots. I have tried Round-up and they grew back next year. By pulling out by the roots you get the whole plant.

Bleach and lots of hard work digging. Mint grows through its root. To kill the plants and keep them gone you have to get all of the root system.

There are types of weed killers which might help to kill mint plants, which can be sprayed and digging them up may also help.
