Shopping Guide for Weed Killers

Invasive plant species can take over your lawn and keep it from looking as green and nice as you want. Crabgrass is a common type of plant that thrives in most conditions, but you also need to worry about plants such as kudzu. Kudzu started as an ornamental grass that landscapers brought over from other countries. They didn’t realize how quickly it would grow and spread or that it could climb buildings. If you drive through the south today, you’ll find this bright green plant growing on the side of the road and covering abandoned buildings. Other types of plants are just as pesky.

The main problem with weeds and dangerous plants is that they invite animals into your yard. Not only do cats, squirrels and other types of wildlife use your yard as their play place, but they also use it as a bathroom. Some animals will eat your healthy grass and attack your decorative plants too. That is why we created a list of the best weed killers that you can use on your lawn. Our list includes concentrates that you can mix with water to create the perfect mixture and others that you can spray as-is. Find the best weed killers on our list of the best of the best.

Expert Tip

Wearing gloves on your hands and a mask over your nose and mouth will keep you safe when spraying or applying a weed killer.

Types of Weed Killers

Residual Weed Killers
One product that you can buy is a residual weed killer. Also known as a soil-acting killer, it attacks weeds through the soil. When you apply the liquid, it will penetrate the ground and kill the soil and anything that comes into contact with the dirt. Instead of just killing those weeds when you apply it, it will keep working due to the residual traces of liquid left behind. This is the best type to use around garden pathways, sidewalks and driveways. You should not use it around large areas of vegetation as it will kill the neighboring plants on top of the weeds.

Contact Weed Killers
If you notice an invasive weed taking over your lawn, reach for a contact weed killer. We cannot recommend this type for gardens or on plants that you eat or touch because it remains in the environment for months or longer. Contact killers work faster than any other type of weed killer and can eliminate some plants in as little as 24 hours. There are selective types of contact weed killers you can buy that work on certain types of plants but not on others. When you want one that works on all the weeds in your lawn, you should look for a non-selective product.

Systematic Weed Killers
When you find yourself struggling with weeds that won’t stop growing, consider using a systematic weed killer. It’s designed to kill weeds from the inside out. The way it works is quite simple. You’ll spray or apply the substance on the leaves and any other spots that you can see. The leaves will then transport the liquid through the branches and into the roots, which will then carry it to all other parts of the plant. One of the issues of using a systematic killer is that it can spread to other plants.

Organic Weed Killers 
Organic weed killers are helpful for those who have kids and pets. No matter how close of an eye you keep on your kids, they can pick a leaf up off the ground and put it in their mouth before you have a chance to act. Organic weed killers use natural ingredients and are safe to use around all types of plants. You don’t need to worry about your pets chewing on the grass or your kids eating leaves because the substances are safe. They’re usually safe to use on vegetable plants and fruit trees and bushes too.

What to Do in Case of Weed Killer Ingestion

  • Reduce the risk of accidental ingestion with signs that you put up when you spray a weed killer
  • Check the packaging for the number of poison control and call that number or 911
  • Follow the given instructions
  • Keep family and pets away from the person to prevent them from touching or ingesting the weed killer

Best Product for the Money: Compare-N-Save Concentrate

When you want an affordable product that will work on most types of weeds, you need a concentrated option like the Compare-N-Save Concentrate. It comes in a one-gallon jug that you can use to make up to 85 gallons of spray.

When used as directed, this concentrated liquid can kill weeds growing on a lawn up to 25,000 square feet in size.

Unlike other affordable products that simply kill the weeds you see, this product reaches deep into the ground to kill the roots of those weeds. This prevents the weeds from returning.

Compare-N-Save Concentrate kills weeds but will not affect your groundwater or lawn.

Top Budget Product: Weed Stop Concentrate

Save even more with Weed Stop, a concentrated weed killer from Spectracide. This small bottle provides multiple applications and works on more than 200 types of common weeds. Designed to work overnight, this product is easy to use too. You can mix up the right ratio of weed killer to water, spray your lawn with the solution and wake up to find that it worked as you slept. Weed Stop becomes rain-proof in around three hours and will go after the root systems of weeds to kill all traces of those pesky plants.

This is the top product for those on a budget because it’s a concentrated liquid that you can mix with more or less water based on the type of weeds you want to fight.

You can also purchase a ready to use spray that comes already mixed with water. As Weed Stop gives you six bottles of the concentrated formula in each package, you get enough weed killer to treat your lawn all spring and summer and into the following year. You just need to make sure that you check the expiration date listed on the bottle and that you store the weed killer in a safe place away from children and pets.

Expert Tip

Only use weed killer when the temperature outside is below 85 degrees Fahrenheit to avoid damaging your lawn.

Best for the Environment: EcoSMART Organic Weed and Grass Killer

One of the most effective weed killers on the market that will not harm the environment is the Organic Weed and Grass Killer from EcoSMART. This product is 100% organic and uses only natural ingredients that will protect your lawn and plants while targeting all the weeds on your lawn. It uses clove oil, which is the same oil that you can use to reduce pain associated with a toothache. The clove oil leaves behind a pleasant and slightly spicy fragrance as the product dries.

This is also a good product to use if you have kids and animals running around. The organic formula is safe for kids to touch and for animals to ingest. Even if your kids want to play outside and you need to let the dog out while you spray, you can let them safely use your lawn. EcoSMART guarantees that its Organic Weed and Grass Killer will not contaminate groundwater sources either.

You should have your kids wash their hands after coming into contact with the weed killer. Though it will not harm them, it can affect their taste buds if they touch it and then touch their mouths.

Best All-Around Weed Killer: Ortho Weed B Gon

Weed B Gon is the best all-around weed killer because it is easy to use and costs less than some of its competitors. The one-gallon size comes with an included applicator that you can use when applying the liquid to your lawn. A comfort wand feels comfortable in your hand as you spray every square foot of your lawn. This handle directs the spray exactly where you need it to go and reduces the fatigue that you felt when using a weed killer in the past.
