We talk you through the considerations when it comes to buying Poison Ivy Killer, knowing what is safe, which features you should consider and the application of weed killers. What are the best ways to effectively kill this very hazardous and annoying weed?

Picking the best Poison Ivy killer

The following features are those we have considered when it comes to picking the best weed killer for Poison Ivy, it is about prioritizing one type of feature over another. Some people might need a waterproof option if they live somewhere there is a lot of rain.

5 Best Poison Ivy Killers - Make It Safe WayType

What type of weed killer is it, and how is it applied? Some have sprays, others have wands and other forms of applicator to allow you to get your weed killer onto the weeds, and only the weeds you want to kill. Spraying everywhere can be a recipe for disaster, some of these weed killers are really good at their job, but they aren’t always able to differentiate between different types of weeds. Don’t risk using near your flowers, make sure you have the right method of applying only to the weeds you don’t want.

Rainproof

If you live in an area where it feels like it rains all the time, then a rainproof poison Ivy killer can be essential. Rain washing away weed killers can be a big issue, and the best weed killers for Poison Ivy are rainproof, this means that after a certain amount of time (sometimes as little as 30 minutes like the Roundup Poison Ivy Killer) the killer will be safe from the rain. Even if there is a downpour, it won’t wash the weed killer away or move it so it damages plants you don’t want to kill.

Active ingredient

In each of our Poison Ivy killer reviews we have mentioned what the active ingredient is. This is the chemical or compound that actually kills the Ivy. It may well also kill other things, including over 70 different weed types that can commonly be killed by the weed killers on this list. The BioAdvanced 704655A model advertises that it can kill over 70 different types of weeds.

Triclopyr is an example of one of the active ingredients that can be found in Poison Ivy Killers. This is, according to Wikipedia, “an organic compound in the pyridine group”. It can be dangerous to birds, for instance, so it could be worth checking that whatever the active ingredient is, is not likely to cause a huge issue for the wildlife. Some compounds will also kill plants and things you certainly don’t want to lose from your yard.

Capacity

This is one of the more self-explanatory features. How much is in the container? It is worth looking at this if you have a smaller or a larger area that you need to cover. There’s no point in buying a huge amount of weed killer for a small yard with the first sign of weeds. However, if you are a landscaper or gardener, it might make sense to always have a large amount of Poison Ivy killer in the truck.

The largest capacity model on our list is the Ortho 0475705 GroundClear, which can help with huge areas. You won’t run out over the first use.

Speed

How quickly does the Poison Ivy killer start to kick in? Does it take ages to get to the root of the Ivy or does it start to work the next day? Some weed killers, such as the Ortho options on the list, can start to have an impact within 24 hours. It will take longer than this to completely kill off your Poison Ivy, but it is helpful if you can see that it is working. You don’t have to worry about your weed killer and whether you have chosen a model that doesn’t do the job.

Safety features

5 Best Poison Ivy Killers - Make It Safe WayAre there any safety features? A lot of the magic wands and sprays included can help you to ensure you don’t get the weed killer on you, or that it doesn’t get sprayed where you don’t want it so it could be a hazard to your pets.

Other safety features may come in terms of the ingredients. Safe weed killers have minimal impact upon the wildlife, and use ingredients, including active ingredients, that won’t hurt your pets, even if they are curious about the Poison Ivy. You may need to take your own precautions such as wearing goggles if you are worried.

Best time to kill poison ivy

Obviously, the earlier you catch and kill Poison Ivy, the better. If it has the chance to grow and its roots set themselves in your yard then it can be very tough to get rid of the Poison Ivy.

Like a lot of other weeds, the Poison Ivy and Poison Oak are most sensitive when they’re growing at their quickest, which is often when the weather starts to improve, this can be either in the early summer or right in the heart of spring.

Usage tips

There are some tips for using Poison Ivy killer and getting the most out of your killer and ensure that you get rid of the Poison Ivy.

  • If you are worried about plants that are near your Poison Ivy, try not to get a multi-purpose weed killer that will just kill all organic matter, as you might do damage to your plants.
  • Pay attention to environmental guidelines. Some of the weed killers made 10-20 years ago could be very bad for the environment.
  • Remember that you might have to apply more than once. If you have weeds that are deeply rooted into your yard then you might have to apply weed killer in multiple spells to ensure that it dies away.
  • Keep an eye on the weather. A dry day is best even if you are using a waterproof weed killer.
  • If you can do a ‘sweep’ of the yard before the winter, you will avoid having to deal with the winter-hardened weeds that have survived through the difficult winter.
  • Always be careful to ensure that the weed killer doesn’t get on you, and that it is not easy for your pets to get access to.
  • Always read the instructions from the manufacturers, these tend to be different depending upon which model you go for. Each manufacturer has its own way of helping you to apply the weed killer, so you should read how to use the sprayer, whether it needs dilution and more.


It can be intimidating using a weed killer for the first time, but you shouldn’t be able to do any permanent damage.
