How To Get Rid Of Ants That Have Huge Mounds In The Yard? It’s not a big deal if your house has a small number of ants in the outdoor area, but if you have a massive infestation or the ants start to move into the interior of your house, you’ll have to take action.

Ants can proliferate in great numbers, and most of them will hide in an anthill on your land. An anthill can be easily identified because it appears on your lawn like a big mound.

Other times, they may be more challenging to locate because they are hidden away in a secluded part of your home. Worse, if you’re dealing with carpenter ants, the colony could be anywhere indoors, such as a wall hole or basement corner.

This essay will show you eight techniques to dismantle an anthill. These are a combination of home treatments and the usage of professional insecticides. Continue reading to learn how to deal with an ant infestation on your property correctly.

How to get rid of ants that have huge mounds in the yard?

Ants are one of the most commonplace family pest troubles globally. Aside from a trail of ants crawling around your property or a swarm of ants emerging in droves to consume fallen food or sweets, the most obvious sign of an ant infestation is the formation of an anthill.

Fire ants are among the most frequent ant species that build anthills, particularly in the southern United States. If you have fire ants, your yard will quickly turn into a minefield of aggressive, stinging ants.

Once the queen has mated, an anthill will usually form. The ant queen is prone to acting promptly after mating to provide a safe underground habitat for the colony to survive.

As the ants multiply, their actions lead the hill to grow larger as they build a network of tunnels that gradually transform into passageways, chambers, and multiple exits. Given the size of the entire network, this can be an insensitive process to complete.

About an Anthill

An anthill is a mound of earth commonly found in a garden or backyard. It consists primarily of soil, small rocks, sand, clay, and other decomposing organic material. Anthills form due to the queen and worker ants attempting to provide a secure haven for the entire colony.

The mound’s structure is primarily due to ants dragging subsurface dirt out into the entrance. The dome-like shape of the nest is the consequence of continuous earth movement. Worker ants develop tunnel networks underneath as the colony expands from tens or hundreds of thousands to millions.

In rare circumstances, worker ants might mix sand and mud with tiny sticks to cement the mound’s intrinsic structure. As a result, the nest is better protected from extreme weather conditions such as heavy rain and powerful winds.

Anthills in thickly forested locations are covered with plants growing on the edges of the mound due to the seeds ejected by the ants while working on their colony’s home.

How Do You Locate Your Anthill?

You can inspect once you’ve spotted ant hills on your property. Inspect the area to see any other mounds, look for ant activity and ant trails. This will assist you in determining where you should apply ant pesticides.

What to Search For

Ants build ant mounds in regions where food is plentiful. Ants will develop an ant mound nearby to move to and from their nest inside your home to forage if you do not keep up with regular cleaning and cleanup both inside and outside your home. They accomplish this by spreading out pheromones used to indicate ant trails.

What You Should Look For

When ant hills are established in your yard, they are usually obvious. In other cases, they may be hidden in a remote location. If you detect an ant path, pay close attention to it and follow the ants as they walk; they may bring you directly to their anthill.

What Is The Best Way To Remove Anthills?

Eliminating ant hills can drastically diminish and decimate an ant infestation. There are numerous approaches to demolish an ant mound, and we’d like to share eight of the most effective ones with you. Whether you need to cast off the anthills obviously or with an expert insecticide, it is up to you.

Boric acid 

Boric acid is a good substitute if you don’t feel like pouring boiling water into the anthill. Boric acid is one of the most widely used pesticides for controlling ants. You can use it as a powder and sprinkle it straight over and around the hill’s entrance.

Boric acid

Boric acid is a highly toxic substance that can kill ants when they come into touch with it. You could make a paste out of it by joining it with water and sugar to make it even more effective.

Sugar aids in the concealment of the chemical and the enchantment of ants. The water dilutes the solution, allowing it to flow through the ant hill’s difficult-to-reach tunnels and chambers.

Water on the Boil

Boiling water is a quick and easy option that you can use right away. Bring a saucepan of water to a boil, then pour it over the ant mound.

Boiling water

The water will gradually flow through the entire network of tunnels and flood the colony; the heat of the water will kill any ants that come into contact with it. Furthermore, the heat will cause the tunnels to collapse.

This may give the impression that the problem will be resolved in a single blow, but this is not always the case.

The one disadvantage of this strategy is that any ants buried far deeper will have enough time to flee the colony. If there are survivors, you will most likely discover traces of ants attempting to rebuild their territory within a few days.

Making it Flat

If the anthill is very substantial, a simple remedy is to use a rake to remove the anthill and flatten out the ground, which will destroy the entrance to the hive. This will irritate many ants and convince them that the region is no longer safe to dwell in.

On the other hand, the ants will rebuild after that, so you’ll have to keep at it for a while before they receive the word that the region is permanently harmful. However, if you want to eliminate chemicals, this is the way to go.

D-Fence Dust

D-Fence Dust is a cloud of simple insecticidal dust commonly used to treat cracks, fissures, and access points to homes and structures. It’s ideal for treating those hard-to-reach locations where pests hide. However, if you see fire ant mounds in your yard, you can use D-Fence Dust.

For optimal results, sprinkle about 0.5 ounces of D-Fence Dust (about one tablespoon) over the top of the ant mound while temperatures are between 65 and 80 degrees F. Do not disrupt the bank or wet the dust in.

Allow the dust to operate for 3 to 4 days for optimal control. Make sure that you are not using actively used culinary utensils, such as spoons or measuring cups, when measuring out the dust.

Directly Apply Supreme IT to the Ant Hill

Supreme IT Insecticide is perfect for immediately treating ant hills since the active component (Bifenthrin) is efficient against a wide range of ant species and has a lengthy residual impact. The drench approach is one of the most effective ways to eliminate an ant mound in your yard.

To accomplish this, dilute one teaspoon of Supreme IT per gallon of water and use 1 to 2 gallons of the completed product in a sprayer to spread the solution over the top of the mound, allowing the dilution to flood the entire anthill.

Drenching is good because it will enable the pesticide to reach the ant queen, killing her and preventing reproduction. To achieve the best results, treat a 4-foot-diameter circle around the mound.

Use bait stations.

When you have pets or children, utilizing bait stations instead of directly putting boric acid to the anthill is recommended. Bait stations keep the poison out of children’s sight and reach while offering easy and tempting access to its target insects.

Furthermore, ants that have visited the station bring the pesticide chemical back to the anthill, killing the remainder of the colony in the process. Place the bait station precisely adjacent to the hill’s crater to ensure that most ants come out of the hound pass through it.


Right here in this text, we’ve discussed the information through which anyone can quickly get rid of anthills. By examining anthills, we also learned that anthills aren’t as simple as they appear.

Beneath is a community of tunnels and chambers meticulously and patiently created by worker ants for various unique reasons. They have compartments for their meals, resting, and the queen’s eggs.
