How to get rid of:
Try spraying a mix of 1 ounce vodka, 2 cups of water and a couple drops of dish soap on weeds with good sun exposure. This will often dry them out and kill them. It doesn’t work well in shady areas. Also be careful not to overspray onto any of your regular plants, the vodka will dry out whatever plants it hits.
