This can be very difficult. Is this a small area, or throughout the lawn? You can try pulling as many up by hand as possible. The next step will be to make sure that whatever comes up doesn't flower. You will have to keep cutting it to keep it from spreading its seeds. What is underground will be difficult. You can try pouring boiling water on the most aggressive areas. This will kill dense patches without making the soil toxic.
