Few plants have a reputation as notorious as poison ivy. Known throughout several communities for being irritatingly pervasive, leaving a dreaded red rash if it touches bare skin. The urushiol oil found on the leaves gives them their trademark shiny appearance and causes near-instant inflammation upon contact.

Poison ivy can be recognized by distinctive three-leaf clusters and the reflective sheen of the oil or sap on the leaves and appears in moderately shaded areas of forest or gardens. Two related plants, poison oak, and poison sumac have similar effects on the human body but are somewhat less pervasive and easier to recognize.

The appearance of poison ivy anywhere on your property should be cause for immediate action. The plant can spread fairly quickly and make enjoying a yard or garden all but impossible. Getting rid of poison ivy is even more important than everyday weddings, as poison ivy can be excruciatingly painful to a grown adult and actually dangerous to pets and children who might try to eat the leaves.

Although it is easy enough to simply cut poison ivy down and throw it away, the plant possesses significant regenerative capabilities and will usually regrow in short order. A gardener’s best bet to rid their property of poison ivy is a powerful chemical herbicide applied as directly as possible to the roots of the plant.

As poison ivy tends to be found in areas that see relatively high traffic – lightly wooded trails, well-worked garden soil, and sunlit front or back yards – a specialized herbicide should be used to avoid damage to desired plant life and residual effects on a passerby. It can be worth doing some advanced research to find out what kind of spray is best for the area before buying, as selecting the right herbicide will avoid damage to any benign plants and often prove more effective than guessing and checking.

Many people shy away from using chemical treatments on their lawn at all, preferring a more organic method of weed control that does not risk the side effects and aftermath of chemical treatment. While there are certain appeals and advantages to this approach, poison ivy may be the time to make an exception. It is among the more harmful weeds likely to be found in their yard and can regrow easily enough. No half measures will be sufficient to eradicate its presence.

A possible bright spot for any landscaper facing off against poison ivy is the reassuring knowledge that they are far from the first to have had this problem. Numerous products line the shelves of any farming or gardening supply shop that are designed specifically to do away with troublesome poison ivy outbreaks.

With so many options of how to handle poison ivy, it can be hard to decide which one is the best choice for keeping your yard clear. Here are the ten best products you can choose to keep poison ivy out of your plants this year.

Helpful Hints:

Although marketed as a way to get rid of poison ivy, take note that most of these products can kill off other weeds as well. Use this to your advantage to create a better budget for your gardening needs.

By contrast, poison oak and sumac can have stems with different enough composition that they may actually require different products to remove. Check labels carefully to make sure you have selected the right herbicide for the plants in question.

Keep in mind that although the plant may be dead, the harmful side effects of poison ivy are produced by contact with the oily resins found on its leaves. Even a dead poison ivy plant should be handled with long tools if possible, or thick gloves and fully clothed if not – not shorts and T-shirt while tackling these plants.

Once you have killed the plants off, make sure to dispose of the dead poison ivy as quickly as possible in a yard waste collection program. Burning or mulching poison ivy can present a serious hazard to you and those around you.

Herbicides like the ones listed above may be intended for use on plants, but they are still potent chemical agents and can be harmful to humans and animals as well. Keep pets and small children out of a treated area for a minimum of seven days from the day of treatment. If the herbicide was used in a grazing area for livestock, consider adding several days for safety.

These are topical herbicides, meaning they can harm you even if not inhaled or injected. Use these products only while fully dressed, including long pants, long sleeves, and closed shoes. For added safety, use an extended sprayer wand and face mask to prevent unnecessary exposure to the spray.

One thing that many people overlook especially when ordering herbicide online, is that the product you are ordering may be subject to restrictions at its destination. Before buying a poison ivy killer take a moment to familiarize yourself with local regulations on chemical herbicides and permissible methods of use.

If you do come into contact with poison ivy while you are spraying, immediately remove contaminated clothing, shoes, and accessories. The irritant oils can adhere to any of these and spread from one to the other. Wash the area with soap and water and apply a cool compress for 15 minutes at a time.

If available, apply calamine lotion to soothe symptoms and speed up recovery. Seek medical attention if symptoms persist or worsen, or there are signs of a more severe allergic reaction.

When applying a product to kill poison ivy, try to choose a sunny day with moderate temperatures. This will make the plant’s pores open and absorb the weed killer faster, speeding you along to your goal of a weed-free lawn.
