How to eliminate poison ivy along fence lines safely
By My Yard Editorial Team · 7/28/2026
The Quick Answer
Cut the vine at the base and immediately paint the stump with a triclopyr brush killer — that's the highest-success method. Reapply to regrowth in 4–6 weeks.
The Witty Breakdown
Every part of the plant carries urushiol, including bare winter vines and the roots. Dead plants stay toxic for years.
Foliar spraying tall vines mostly wastes herbicide on leaves 15 feet up while the root keeps going.
Step-by-Step Fix
- 1
Wear disposable nitrile gloves, long sleeves, and eye protection.
- 2
Cut the vine at ankle height and again at chest height.
- 3
Paint the fresh cut stump with concentrated triclopyr within 5 minutes.
- 4
Bag all debris — wash tools and clothes separately with degreasing soap.
Pro-Tip / Do Not Do This
NEVER burn poison ivy. Inhaling that smoke can put you in the hospital, and that is not an exaggeration.
