Behind my home my yard is covered up with poison oak or poison ivy one

I use a mixture of javel water and water,I mix mine 1 to 1 ,Put it in a spray bottle ,then I spray plants individually,soaking them,A few days later brown leaves and they die,be wary of dead foliage this plant can bite even after death,handle with care,both plants and spray.

I'll tell you what some farmers I used to live near would do. They would use flame-throwers. Not the kind in super violent movies. But their flame-throwers could burn down a thicket of briars or a patch of poison oak or ivy in minutes. The farmers said it also got rid of snake nests. Then they could let the cows in the pasture or cultivate a field. Flame-throwers are available at most farm supply stores. Best wishes. 😇

Suit up and dig it out, and use a chemical solution. That should eventually be a long term solution. Good luck!

Rent a goat...poison ivy is their crack!

3 cups white vinegar

1/2 cup table salt

1 tablespoon liquid detergent or soap (I use Dawn) for stick-to-itiveness.

Directions

1. Mix vinegar and salt until the salt is completely dissolved. Stir in liquid dish soap, and pour into a spray bottle.
2. Spray onto the green growing leaves of the plants.
3. Wait a week, then repeat on any survivors. Best time to apply: during a dry spell.
