Poison Ivy Killers That Work

Poison ivy can quickly turn your gardening experience into a nightmare. This pesky plant is not only hard to get rid of but can also cause serious allergic reactions when it comes into contact with the skin. 

You can use manual or chemical means to get rid of poison ivy plants.

The former involves using a lot of elbow grease to pull out the entire plant including roots hidden underground. Given the difficult nature of the manual approach, most people prefer the chemical approach when it comes to killing this weed as the method not only gets the job done, but also reduces your risk of getting into contact with the leaves of the plant.
