I would use a combination of things to kill it off! Boiling water will be the first thing. Pour this on the spot twice a day for a few days, just for good measure.
After the boiling water treatment, I would cover it with plastic for a few weeks at the least. This will help to solarize and kill off any remaining seeds, or runners.
