How to kill ants in your lawn? STOP anthills now!


Most gardens have some form of a lawn. They are laid in most new gardens as a way to provide entertainment space for adults and a playing area for children. But lawns can sometimes also be home to ants. These ants can become a real nuisance and destroy your lawn from beneath. Anthills have been a pain to me, so I set out to learn how to kill the ants in my lawn.

How to kill ants in your lawn? There are various ways to kill ants in lawns, Some are chemical and others are organic. Natural ways include neem oil, cinnamon, hot water and even dishwashing detergent. Depending on how the lawn is used will depend on the treatment.

Our homes are just like our castles. Unfortunately, they are not immune to attack by massive armies of tiny ants. Ant invasions are not only annoying but also dangerous to your health and the health of pets living in your home. Who could’ve thought that insects as small as ants could cause so much damage? Yes, they could. Despite being so tiny, these animals come in droves and work together.

Ants are a nuisance and can quickly destroy your lawn if you’re not keen, damaging all the beautiful gardens and foliage by creating mounds and destroying vegetation. If not eradicated in time, some ant species move into home structures where they start setting up colonies, weakening structures, and contaminating food.

How are anthills constructed in lawns

Before we go into how to kill ants in your lawn, I think it is important to understand how an anthill is constructed. Anthills are a maze of tunnels and chambers that can stretch to over 3ft deep and 4ft wide. Impacting the entire colony with one application of anything will be nigh on impossible. A regime of treatments will be required in order to kill off the entire colony.

Types of Ants That Are Common in Lawns

 Below are three types of ants that are common in lawns, along with detailed characteristics about how they look. This will help you to quickly identify these ants when your garden gets infected.

Field Ants

This doesn’t refer to a specific species of ants. Instead, the term field ants refer to several species of ants that are fond of living in lawns and fields.

Appearance

Field ants vary a lot in appearance because they’re made up of different species. Most of them are usually about a quarter of an inch long. They also vary in color, from black to red to brown. Field ants are ubiquitous, and you’ve probably seen them.

How Field Ants Damage Your Lawn

 Field ants build and live in mounds. These mounds are first built underground before the ants start pushing up the soil to create visible ant mounds in your lawn. These mounds usually very large, spanning up to three feet or more.

These mounds damage the grass on your turf. The ants also destroy the grass’s root structures, which leads to brown spots developing on your garden. These mounds can also make it hard for you to mow the surface of your grass.

Farming Ants

Farming ants are also a broad category of ants. Farming ants secrete hormones that attract other insects, which these ants use as food. Aphids are among the most common victims. Aphids produce honeydew, a substance that has sugar in it. These aphids are harmful to the health of your lawn.

Appearance

 They’re almost identical to field ants. Farming ants are also small and vary in color from black to red to brown.

How Farming Ants Damage Your Lawn

Farming ants attract aphids, which can cause serious harm to your lawn. Aphids survive by feeding on young plants, especially young shoots and stems. Aphids can eat up and destroying your yard. Moreover, these aphids can also destroy any other type of vegetation and transmit viruses.

Army Ants

These are the most destructive type of ants found in our yards. Army ants are aggressive and are mostly found in the Southern United States. Army ants can venture into lawns and other types of densely forested areas to look for food.

Army ant colonies are capable of diminishing the food sources of other animals, including beetles, birds, and reptiles. As a group, army ants are capable of killing Chicken, lizards, Goats, Pigs, cats, dogs, and other small animals.

Appearance

Army ants are very tiny insects that are dark-brown or gold in color. With time, they tend to grow bigger and develop stingers and hooks.

How Army Ants Damage Your Lawn

Unlike Farming ants and Field ants, Army ants don’t damage your lawn by building mounds and attracting insects. Instead, this type of ants moves together in large colonies destroying all the foliage in an area. A colony of army ants can eat an entire section of your lawn, ruining your beautiful grass and vegetation.

Army ants destroy properties using numbers, with a colony having thousands of ants. Army ants attack plants and insects by swarming them in large numbers. Army ants also bite anything that gets in their way. If your lawn is infested with army ants, your children and pests are susceptible to bites. This puts their lives in danger.

Methods of Killing Ants in Your Lawn

If you have a lawn in your home, it’s of extreme importance for you to be in the know about the latest techniques on how to exterminate ants in your lawn. This will not only allow you to enjoy your lawn and keep it free from the menace caused by these creatures but will also help in protecting your beautiful plants and allow them to mature.

Though, you’ll need to be very cautious of the method used, as using a wrong approach may destroy your garden. First, you’ll need to be specific about the type of ants that have invaded your yard before you choose the best method of eradicating them.

  • Using Boiling Water
  • Peppermint
  • Raking ant mounds
  • Spraying soap and water
  • Vinegar
  • Cinnamon
  • Using Olive Oil and Dishwashing Liquid
  • Sugar and Boric Acid
  • Chili Pepper
  • Diatomaceous Earth
  • Anthill killer gels. (Chemical)
  • Anthill killer poison (Chemical)

Natural & Home Made Methods Vs. Artificial Methods.

Killing ants in your lawn can either be done via natural &homemade methods or artificial methods. If you want to get rid of the ants in your home completely, you first need to target the source. In this case, the nest. There several ways to destroy ant nests; this includes natural methods or using specific chemicals to kill these ants.

Using home remedies has its drawbacks, and sometimes it’s slower. On the other hand, chemicals are effective but may end up destroying your lawn. But in the interest of being comprehensive, I’ll cover both methods of killing ants in your lawn.

Natural & Home Made Methods of Killing Ants in Your Lawn

There are several natural and home remedies that can be used to kill ants in your lawn. These methods include;

Using Boiling Water.

Poring boiling water into an ant’s nest is the simplest and most widely used method of kill an ant nest. Simply try and locate all the entrances and pour boiling water into them. This will immediately kill most of the ants inside. Although some ant hills may appear small, most of them are bigger underneath and are home to several colonies. Using boiling water has some drawbacks though. They include:

  • Boiling water won’t kill off the entire colony because of the big size of the nests.
  • It often takes several attempts to notice success
  • Using hot water can result in boggy and wet areas in your lawn.
  • Hot water can scald your grass, turning it to brown.

Peppermint

Did you know that Peppermint is an insect repellant? You can plant Peppermint in your home or use it as a natural remedy to get rid of ants. Ants hate the scent. Apart from repelling ants, planting this plant will leave your home smelling minty fresh! Plant peppermint around the perimeter and entryways of your home.

You can also place peppermint cotton balls in areas where the ants frequent. Like most essential oils, keep this oil out of reach of pets, who may become very ill if exposed to this oil. Peppermint essential oil can be found at your local grocery store.

Raking ant mounds

This might sound too simple to work, but it’s among the modest and the most effective ways of getting rid of the stubborn ants in your lawn. Ants prefer building their nests in quiet, dry and sandy soils, and if the mound is given enough time to harden, it will offer protection to the nest, making it difficult to remove.

Continuously raking the mounds and spreading the soil around disturbs the ants, their network of tunnels, and entrances. This will make them leave in search of a new peaceful home.

Spraying soap and water.

Start by choosing an eco-friendly soap (to enable the environment around it to thrive, including the grass on your lawn) mix it with water and spray it into and around the mounds. You can also use hot water, but avoid making the water too hot because hot water destroys grass. Soap will suffocate the ants to death, and diluting it with water lessens the chances of the soap damaging your grass.

Vinegar

Mix equal portions of water and vinegar in a Spray Bottle. Directly spray the mixture on the ants to kill them. You can also pour this mixture into ant hills to kill ants inside their nests.

Cinnamon

Cinnamon is also a great option when it comes to killing ants. When ants inhale the scent of cinnamon, they suffocate to death. You can sprinkle ground cinnamon on the ants’ path or around anthill openings. You can also use cinnamon essential oil to repel ants. Mix a few drops of this oil with water and spray on anthills, and trails, and anywhere around your lawn where you notice ant colonies.

Using Olive Oil and Dishwashing Liquid

Another common home remedy of killing ants in your lawn is mixing olive oil with dishwashing liquid and spraying the ants with it. This solution penetrates the ants’ exoskeleton before suffocating the ants to death. Again though, this method can take a while to work, and depending on the detergent used, you may end up bleaching the grass, making the area paler than the entire lawn.

Using Sugar and Boric Acid on Your Lawn

The idea behind using sugar and Boric Acid on your lawn involves mixing the two to form a paste and putting the paste in certain areas of your lawn, preferably near the ant nest. The sweetness in the sugar will attract the ants to it. These ants will take the sugar back to the nest as food for the rest of the colony. The Boric Acid in the mixture will kill the ants.

The disadvantage of using this approach is that the sugar and boric acid needs to be mixed very keenly. If you use less Boric Acid, you won’t kill any ants. On the other hand, if you use too much Boric acid, you’ll end up killing the first ant that takes it before it’s transported to the nest. Boric acid also damages the grass.

Chili Pepper

Another effective home remedy you can use is chili pepper. Ants hate chili pepper. Black pepper can also work. Locate the anthills and sprinkle some pepper around them, and if possible, use the pepper to create a barrier that will stop the ants from moving around your lawn.

An alternative solution is mixing the pepper with water and spraying or pouring the resulting solution into the mounds. The pepper won’t kill the ants, but it will make them vacate from their nests. You can also sprinkle some spice on the ant mounts to repel ants. If you have coffee grounds, you can mix it with pepper to make it more effective.

Using Food-Grade Diatomaceous Earth

Food grade diatomaceous earth is a gardener staple made from algae fossils, and it’s a natural insecticide. When ants eat the diatomaceous earth, they become dehydrated. This gardener slowly kills any ant that ingests it. Using Food-Grade Diatomaceous Earth is a great way to kill an ant mound, as it allows the ants to survive long enough to take the product back to their members of the colony in the nest. Ensure that you only use food grade–diatomaceous earth.

Chemical Methods of Killing Ants in Your Lawn

Despite being environmentally friendly, most natural methods take time to get rid of the ants in your lawn. The natural components used in these methods are not as lethal in destroying ants compared to using chemicals. Therefore, if you need instant results, you can turn to the chemical treatments discussed below

Using Ant Hill Killer Treatments

Applying ant killer treatments is one way of killing ants outdoors if you’ve numerous ant hills within your home. Although, you should be very careful and wear protective clothing when applying this treatment because this technique involves using chemicals that may harm you if not handled properly. There are two main types of ant killer treatments. They include:

  • Anthill killer gels.
  • Anthill killer poison

Anthill killer gels

Most garden centres sell an ant poison that comes in gel form. This works the same way as food grade diatomaceous earth. Ants are attracted to this sweet gel, which is carried into the ant nest for the queen and her colony to feast upon. Despite being poisonous, the gel is environmentally friendly and doesn’t affect your garden or lawn.

Anthill killer poison.

Ant killer poisons are mostly available in powder form. These forms of ant poison are best used on anthills since they affect plants and may alter the soil composition due to their toxicity. The application should be made into the nests after digging them open.

If you’ve decided to kill the ants in your lawn using powder poison, ensure that you take some precautions beforehand. This includes restricting the poisoned area from access by small children and pets. Also, ensure you make the application on a calm day as the wind might carry the poison to neighbouring gardens.

Before applying any anthill treatment, ensure that you choose the right product. Anthill treatments are available in various forms, including solid and liquid treatments. Whichever option you settle for; you’ll only be able to kill the ants in your lawn if you use the treatment correctly.

Also, ensure you follow the instructions to the latter when using your ant treatment. After you have finished applying the ant treatment, don’t use the container for other purposes to avoid contamination.

Using Ant Bait Stations

If you don’t want to spray your lawn, or to sprinkle the powder around it, using ant bait stations is an excellent alternative. Put a bait station near the ant nest, and the ants will take the liquid t back to their queen and colony members in the nest.

This active ingredient will spread through the entire nest, killing the entire colony within no time. I personally recommend having one or two bait stations around your lawn to kill off any ants before they fully establish their colonies.

Applying Insecticides to Your Lawn

Not all ants build mounds in your lawn, some simply make trails by eating everything that’s before them. A good example is the army ants, a breed that’s very aggressive when it comes to destruction. If you want to destroy this type of ants and keep them away from your lawn for good, the best method is applying insecticide to the entire lawn.

Although this method is time-consuming, it’s worth the effort. Before you begin applying insecticide to your lawn, you should consider mowing the lawn. Mowing your lawn makes it easier for the insecticide to get into the soil and kill the ants.

Once the grass is mowed, proceed with the application of your insecticide. Using a spray option will make the application process easier. After you’re done, ensure you reapply the insecticide at least twice a month for full protection.

Professional extermination.

If none of the methods discussed above has worked for you after ants have invaded your lawn, it’s advisable to consider hiring a professional to handle the invasion. Professionals will make use of the latest products, methods, and machinery to curb the ant’s problem.

Will they return after you kill them?

If you completely destroy their new habitat, the ants obviously won’t return. However, this doesn’t mean that your lawn will be 100% immune to in the future. A nice and soft lawn is irresistible for ant queens! The ants may return but may take several months or years for this to happen. And if they do come back again in the future, at least you know what to do!

Now that you’re aware of several methods you can use to kill ants in your lawn, you should be able to keep your home ant-free, particularly if you’re not fond of destroying ant hills. If you have multiple ant hills on your lawn, you should consider consulting a professional before choosing the best pest control solution.
