You must kill the roots because the plant is perennial. You can use Poison Ivy killer or Brush-B-Gon liquid killer, because you need one that kills woody stemmed plants. I read a safer way to kill it (without sprays) is to spread Rock Salt (like you would use on icy sidewalks) on the plants & water so it will suck it up in the root system & die. Wait until the plants are brown & shriveled. Even when dead, you must be careful though as you can still get an outbreak from their oils. If you cover the plant with large plastic garbage bags to grasp to remove from the ground, the oil cannot get into the air and find your skin. Also, wear rubber gloves when you do this. Do not burn or compost. Throw out in regular trash. If you cut it with a lawnmower, you will splatter the oil everywhere in the air and on you. So don't! The tarp might work if it is thoroughly pinned to the ground. If not, runners will peek out from under the edges. Salt & tarp would work better. If you have any more questions, feel free to email me.
