Perhaps, you were gardening and already noticed those familiar leaves of three growing in your yard. Before they can spread and cause even more trouble, you could try making up a batch of this simple, non-toxic homemade poison ivy killer spray to eliminate the awful invaders before they have a chance to make you suffer.
All you need are three ingredients, a container to mix them in, and an empty spray bottle. Be careful though once you spray because this formula can also kill other plants. Therefore, I suggest trying to shoot the spray in a direct line with your target to avoid any risk to any of your favorite neighboring plants.
I have two other posts that you may also want to read with poison ivy gardening precautions that also help with some useful advice to stay safe outside when gardening. Another informative piece is on how to minimize your contact with poison ivy.
