Buyer’s Guide

There are many different products available to kill poison ivy. Some are made for poison ivy, and others can kill it and other types of weeds and grasses.

This buying guide was created to help you choose the best product for your requirements. It covers the main things to think about when making your decision.

The Type

There are two types of poison ivy killers: natural and chemical.

  • Natural Poison Ivy Killer

Some people choose to employ natural and organic ways to get rid of weeds. Poison ivy can be eradicated without using a chemical herbicide, but it will take time and work.

Concentrated vinegar is commonly seen in organic herbicides. This vinegar is extremely acidic and can damage the plant sections on which it is sprayed. To completely eliminate poison ivy, however, the roots must be removed. Digging or pulling them out will take some effort.

The trouble is that even if you are really careful, you can still overlook subsurface parts of the plant. If any of it is left behind, the poison ivy may sprout again.

Many people believe that a chemical weed killer is the ideal weed killer for ivy rather than an organic herbicide.

  • Chemical Poison Ivy Killer

Chemical weed killers are popular because they work well to get rid of weeds for a long time. They are easier to use than natural methods.

Poison ivy killers usually contain harmful chemicals, so be careful. We recommend you wear protective clothing and gloves when handling such weed killers and wash any clothes that come into contact with them separately.

Glyphosate, Triclopyr, and 2 4-D are the active chemicals of the finest poison ivy killers.

Glyphosate is a weed killer that can kill most plants. It is effective at killing broadleaf plants and grasses. The weed killer goes to the root of the plant to kill it.

Triclopyr is a weed killer that will not harm grass. It kills plants by working from the leaves to the roots.

2 Most kinds of grass are unaffected by 4-D. It is specially formulated to kill plants like poison ivy with hard-to-kill cells. This ingredient will cause the plant's cells to divide and grow continuously, effectively stopping it from growing.

Selective Vs. Non-selective

Some weed killers kill specific types of plants. This is called being selective. Selective weed killers won't kill your grass and other plants you want to keep. If you're worried about damage, choose a selective weed killer.

Non-selective weed killers kill everything they come into contact with. They are good for getting rid of many different weeds, brush, and grasses. However, while using them on your lawn, flowerbeds, or beautiful gardens, you must use the utmost caution.

Ease of Use

Some herbicides are pre-mixed and ready to use. This makes them convenient and quick to utilize for modest operations. It's not necessary to mix it or pour it into a sprayer.

Getting a concentration for larger jobs might sometimes be less expensive. To use it, mix it with water in a backpack sprayer. Alternatively, you can connect the bottle to a hose spray nozzle is recommended. This can assist you in rapidly and easily covering big regions of ground.


Some plants are very hard to get rid of. Poison ivy is one of those plants. You might have to treat an area more than once to completely remove it.

The best poison ivy killers can be expensive, but they can save you money in the long run. This is because many cheaper options often require multiple applications and may not be successful.

How to Use Poison Ivy Killer

Although the directions for each contact lens brand are different, some recommended practices are to be aware of.

Some herbicides are simple to use and require little effort. On the other hand, others may need to be blended with water and swirled before use. Always read the package recommendations carefully to determine how much herbicide to use for your job.

Using a sprayer wand makes it easier to control the best poison ivy herbicide administration. You have greater control over this than with a regular spray bottle. With a wand, you can get through the vegetation in front of you and right down to the roots of poison ivy and other undesired plants (around the roots, new leaves, and sensitive growth).

Saturate the leaves of poison ivy plants for the best results. Avoid using near humans, animals, or water during rainy or windy days. To avoid drift or accidentally spraying other plants, use a sheet of cardboard if at all possible. If required, put on protective gear.

If possible, choose a day when there is no chance of rain. The compounds on the leaves may be absorbed if it rains.

Herbicides should be used to poison ivy in late spring or early summer when the plant is actively growing.

To completely destroy a growth, you may need to use more than one herbicide application. However, keep in mind that certain poison ivy killers can take up to a month to work.
