When you find poison ivy growing on your property, strive to control the growth of this poisonous plant quickly and effectively to prevent it from causing pain and discomfort. Use an herbicide containing either 2, 4-D or 2, 4-DP (or both) to kill poison ivy in your lawn. Herbicides containing these chemicals are safe to use on lawns because they will not affect grass.
Select a day in the first half of the summer when the poison ivy is actively growing and blooming. Temperatures of between 60 degrees Fahrenheit and 80 degrees Fahrenheit are ideal, and calm winds will prevent the herbicide from drifting to desired plants as you apply it. Although some herbicide products are rainproof and will remain effective even when wet, choose a day when rain is not in the weather forecast and when it has not rained for at least 12 hours for best results.
Wear protective clothing as you apply the herbicide. This includes eye protection, long pants, long sleeves, gloves and shoes that cover your entire feet.
Apply the herbicide spray directly to the poison ivy. Do not apply so much herbicide that the leaves of the plants drip with it, but coat all foliage with the spray evenly.
Pull the poison ivy plants from the lawn after they die completely. Wearing full protective clothing, carefully pull the dead plants from the soil and place them directly into the garbage bag. Seal the bag and dispose of it.
Remove all clothing you wore as you handled the poison ivy because the poison ivy toxins continue to stay on the clothing for an extended period of time. Wash these articles in hot water as soon as possible.
