Well, this guide has looked at three of the best options and figured out which one is the safest and most effective. Take a look and see which one will work for you. 

It’s time to be honest about yard ownership. As much fun as it is to have a luxurious plot of grass with maybe some carefully cultivated flowers and vegetables, having a yard still comes with numerous responsibilities. Perhaps one of the most important is preventing the growth of pests, especially ones that are damaging and harmful to the people who live in the home.

Perhaps the most annoying and pernicious pest is poison ivy. This plant is well known for the chemical it secretes, which induces an allergic reaction in most humans and causes rashes, itchiness, and trouble breathing. Although a lot of animals aren’t affected by its chemical secretions, it’s important for humans to stay away because of the reaction.

Reasons to Use a Pesticide

A lot of people try to avoid using pesticides and herbicides, but sometimes the situation becomes so dire that it is necessary. While there are a couple of homemade remedies people can try, they usually don’t have the lasting results that using a genuine herbicide does.

Herbicides tend to attack not only the visible stems and leaves but also reach down deep into the soil to attack the roots and stop the plant from growing back. The pesticide will additionally target any offshoots of the primary poison ivy plant, meaning it will eliminate any smaller versions that have started to grow in the nearby area.

How to Use a Pesticide

If you choose to use a pesticide or herbicide, remember to read all of the instructions and double-check the ingredients. You want to make sure that you are using the product correctly to prevent damage, potential injury, and other unpleasant situations. 

As a general rule, never spray around children, pets, and other living things. Try not to inhale and rinse and wash immediately if you accidentally spray or get liquid on yourself. The ingredients that are poisonous to poison ivy are also hazardous to humans. When possible, wear gloves.

After the herbicide has been sprayed, do not allow children or pets near the area for the next 24-48 hours, or however long the product directs. This is to ensure none of the poison is transferred while it is fresh.

Best Ways to Get Rid of Poison Ivy

If you are still wary of using an herbicide, it is possible to use a natural, homemade remedy. However, these tend to be less effective and will require more work on your end. Perhaps the simplest is pouring boiling water on the main stem of a plant. This will kill not only the growths you see but can also reach into the soil and burn the roots.

Homemade Poison Ivy Killer

There are some alternative methods, including making an herbicide composed primarily of vinegar and dish soap:

  • You will need 1 gallon of water, 1 cup of vinegar, and 8 drops of liquid dish soap.
  • Boil the water and then slowly mix in the vinegar.
  • Then allow it to cool a little before adding the soap and gently mixing so it doesn’t become too bubbly.
  • Spray the mixture on poison ivy stems and roots to kill unwanted growths.

Another version of this mixture replaces the vinegar with salt, which people are more likely to have around the home. The same basic rules apply, so the water needs to be boiled, and then the salt slowly mixed in. Once the mixture cools a little bit, you can then mix in the soap and go to work spraying. 

Finally, there is one more version. This one is more caustic but uses the same ingredients. Instead of using a gallon of water, you instead use a gallon of vinegar and then mix it with 1 cup of salt and the liquid dish soap. This mixture has a strong scent but is highly effective and acidic.

Of course, you can always put on gloves and protective clothing and dig the poison ivy out by the roots so it doesn’t come back. However, this takes physical effort and comes with the risk of developing a rash from contact with the plant.
