How To Get Rid Of Ant Hills​


No one likes having too many ants in their home. However, just getting rid of the ants is not enough. You have to kill their queen to ensure that no ants come again in your yard or garden.

When there are too many ants, they create an ant hill that can be a big problem for you. If you are looking to get rid of ant hills in your home, you are in the right place. Here is everything you need to know.

Ant Hills Explained

Before moving on to the different ways you can utilize to kill ant hills, you need to understand what they are. Ant hills are various mounds of dirt. These hills can have many sizes and can be found anywhere in your yard, garden, or outdoor area.

The composition of the ant hills can also vary depending on the ants. Some ant hills are hard, and some are soft. They can be composed of anything from rocks, pebbles, sand, to branches and soil.

Keep in mind that you will never find ants on top of the ant hill. They live below the surface level, with the queen living on the lowest level. That is because the queen requires the most protection, so it is difficult to get to her. Once you get rid of her, you can kill the entire ant colony in no time.

The Formation Of Ant Hillsant-hill-formation

Ants may be tiny, but they have the intellect to build a complex system of tunnels inside the ant hills. They create these tunnels in the dirt, and they drag and excavate the dirt to the surface level. When they pile this dirt, an ant hill is formed.

Creating an ant hill may seem like a random occurrence to the human eye, but ants use strategy to create them. That is because the ant hills have a few functions to the ants, which include:

  •   Serves as an entry and exit point to the ants
  •   Protects from predators
  •   Controls the temperature inside the ant hill

The simpler the system of tunnels, the smaller the ant hills will be. A massive ant hill means that the tunnels the ants have built inside are complex and strategic. That is why it can take a while to get rid of an enormous ant hill.

Are Ant Hills Deep?

Many people wonder if ant hills are deep and if various methods can kill all the ants effectively. First, keep in mind that an ant hill is deeper than you think. It can range anywhere from two inches to thirteen feet and even more.

Some ant hills are so complex and deep that they resemble cities. The deepness of the ant hill depends on how long it has existed and the types of ants that live there. The longer the ant hill has existed, the deeper it will be.

That is why it is essential to get rid of the ant hill as soon as you spot it. The longer you let it be, the deeper it will get, and the problem will worsen with time.

Are Ant Hills Harmful?

Ant hills don’t harm you in any way, but they are a nuisance to have in your yard. That is because big ant colonies can kill the plants around your yard or garden. Keep in mind that an ant hill has such a strong foundation that even rain can’t deter it from its place.

The ants will not attack you or harm you unless you make the first move, so you will not have to incur any harmful bites or stings. However, if you want your plants and flowers to be safe, you’ll want to remove this nuisance from your yard.

Types Of Ants That Create Ant Hills

The most common types of ants that create ant hills include:

  •   Fire ants
  •   Allegheny mound ants
  •   Texas leafcutter ants
  •   Argentine ants
  •   Harvester ants
  •   Pyramid ants

All these ants create complex structures that are foundationally sound and intact. Keep in mind that fire ants are a nuisance to have in the yard. Their ant hills are made from soft earth, and they don’t have an opening on the top.

That is why it might look like a random pile of dirt to you. They will also sting you when you attack, so you should not disturb the mound when you are trying to get rid of the anthill. Precaution is essential to ensure that the entire process is carried out smoothly.

Getting Rid Of Small Ant Hills With Pesticide

If the ant hill in your yard is not too big, you can easily use a pesticide to get rid of it. Use a pesticide that has a long-term result, so there are no problems for a few months. After the time limit, you will have to treat your backyard once more.

All you have to do is spray the pesticide from the opening of the ant hill to kill them. However, this method will only be effective when ants are incredibly active. You should also refrain from using a liquid pesticide because they don’t reach the queen and are ineffective.

Instead, you should use a powdered or granulated pesticide, as it is effective and offers long-term results. Such a pesticide kills the ants on contact. That is why you should use a generous amount of pesticide to kill all the ants on the hill, including the queen.

Getting Rid Of Massive Ant Hills

If the ant hill is massive, then you have a big problem on your hands. To get rid of these ant hills, follow this step-by-step guide:


1. Mow The Grass

Mowing the grass will allow you to keep your yard safe while creating a perimeter around the ant hill. Wherever the large ant hill is, make sure you mow the grass around it. Your aim should be to cut the grass as low as possible.

Doing so will allow the ant hill to be visible, and it will keep your grass safe from any nuisance. You will also get to see if any ants try to turn away somewhere else. So, make sure the grass is mowed to the lowest.

2. Use An Insecticide

Apply the insecticide around the ant hill where you cut your grass. Doing this will create a barrier so ants can’t escape. After that, you should apply the insecticide on top of the ant hill.

It is not a quick process. Once you have applied the insecticide, you need to leave it for a few days. If the ant hill is too big, you might need to leave it for a week. That is because you need to give the insecticide enough time to reach the queen.

Once it reaches the queen, your plan will be effective. The ant hill will eventually collapse when the queen does not exist anymore.

3. Flatten The Ant Hill

If you don’t have a few days or a week to wait for the insecticide to have its effects, you can start flattening the ant hill to reach the queen yourself. To do this, you can mix an insecticide with soil and sprinkle it in your yard, so the ants don’t have a chance to disperse. This will discourage from creating another colony in the same area.

If you see the queen dispersing, all you have to do is kill it, and your job will be done. However, we recommend that you don’t flatten the anthill, and instead wait for the insecticide to naturally reach the queen in due time.

Natural Ways To Get Rid Of Ant Hills

2. Create An Ant Bait

4. Diatomaceous Earth

Diatomaceous earth is known to dry up the external skeleton of the ants, and they eventually die of dehydration. All you have to do is sprinkle it over the ant hill. It will kill many ants, and it might reach the queen too.

Controlling Ants Inside The Home

If you had an ant hill in your backyard, then the chances are that there might be ants in your home too. That is because many ants invade homes and use crevices and nooks to create colonies. To get rid of this nuisance, you can follow the following methods:

3. Commercial Bait

Of course, commercial bait is an excellent way to get rid of scout ants and the ones back in the nest. We all know that ants love sweet food, and that is present in the commercial ant baits. Wherever you see ants crawling, keep the bait there.
