Poison ivy is a vine that produces leaves that are together in threes. What makes this vine dangerous is the urushiol oil it secretes. This oil can cause human skin rashes that itch excessively. The oil spreads easily, and you want to remove poison ivy vines from your landscape as soon as you see them. You also will want to do this so the poison ivy plant will not grow back.
Put on long clothing and a pair of boots to protect your skin from touching the poison ivy plant. Wear goggles and gloves for even more protection.
Cut back your poison ivy leaves to about 6 inches above the ground. Put the pruned ivy leaves in a trash bag.
Mix an herbicide that contains the ingredient glyphosate as directed on the product label. Glyphosate is effective in getting rid of ivy plants for good.
Spray the herbicide on the remaining poison ivy plant. Make the herbicide doesn't get on any nearby plants because it will kill them as well. The poison ivy should be wet but not dripping.
Wash your clothes as soon as you take them off using the hot water setting on your washing machine and detergent. If you don't wash your clothing, the residual oil from the poison ivy plant will give you a rash if it touches your skin.
Use the herbicide again on the poison ivy plant two weeks after the first treatment if it didn't completely die.
