If your question is how to get rid of poison ivy plants, the safest method would be to use Herbicides. Roundup spray is a popular glyphosate-based herbicide used to get rid of poison ivy. Another widely available herbicide is Ortho Brush-B-Gon, which is triclopyr-based. If you want to relieve the symptoms of contact with the plant, Soothing measures such as cool compresses, oatmeal baths and calamine lotion can help with itching. Treatment may also include oral antihistamines, over-the-counter or prescription-strength steroid creams, and oral steroids such as Prednisone.
Tecnu is a liquid you use in the shower. U apply it and u rub it in. It dries the stuff out and takes about 10 days but it's worth it. Works well. I have bought my fair share of it and have been pleased.
If you kill the poison ivy, when you remove the dead vines bevsure you wear long sleeves/pants &'gloves and remove them and wash in hot waterby themselves so you wont break out with the rash. The dead plants will still have the poison.
