Ants are common pests in the United States and throughout the world. They enter our homes and infiltrate our pantries, costing hundreds of dollars in food waste a year. Some species of ants are even destructive, while others cause painful bites or emit nasty smells when crushed.
Ant infestations in the home always begin outside, and the best way to remedy these pests is to ensure your yard is ant-free.
In today’s article, we are going to cover how to get rid of ant hills in the yard and keep them from returning. But before we begin, let’s take a moment to look at the types of ants who build ant hills in the yard.
Types Of Ants Who Build Ant Hills
Ant hills can be beneficial, but in large numbers they can wreak havoc on your lawn.
There are 10,000 different ant species throughout the world, but not all ant species build ant hills or mounds. The ants who are most commonly responsible for building those unsightly ant hills in your backyard are a few very specific species which include:
- Texas Leafcutter Ants
- Red Imported Fire Ants
- Argentine Ants
- Allegheny Ants
- Harvest Ants
- And Pyramid Ants
Though none of the above species of ants are dangerous, some can bite while others can cause serious destruction to your yard and landscaping.
That said, it’s also important to remember that some ant hills can be beneficial to your landscaping. Ant hills can provide natural aeration to the lawn and reduce problematic larvae below the surface of your turf.
However, in large numbers, ant hills can destroy lawns and gardens, as they destroy plant roots, kill grass, and can even create dangers for people walking through the yard.
When considering how to get rid of ant hills in the yard, remember that ant hill chambers can go up to 25 feet below the surface.
The below video describes the intricate workings of the inside of a fire ant mound.

The “hill” part of the ant mound is actually just a displacement of excess dirt that ants dig up as they build their chambers. Ants don’t live on the surface of the ant mound. This is why simply destroying the ant hill doesn’t result in removing the underlying cause of the issue, which is the ant colony itself.
Ant hills are constructed by worker ants. There can be thousands of worker ants in a single colony, and many species of ants branch out from one colony to another as they become more crowded.
This can result in an ant infestation in your yard that has the potential to find its way into your home. Furthermore, your yard, garden, and landscaping could become compromised.
The good news is that working on how to get rid of ant hills in the yard not only reduces future pest control issues in your home, but it can also help increase your yard’s overall health and visual appeal.
How To Identify Ant Hills In Your Yard
Different species of ants build different types of ant mounds.
In many regions of the United States, ant season is through spring and fall. However, in warmer areas, ant season and ant hills can be a year-round problem. Sometimes ant hills look like other pest issues in the yard, and can be mistaken for rodent burrows or reptile holes.
This can make identifying ant hills a bit more complicated, which can further compound the problem as they grow and get out of control.
Identifying ant hills is the first step to knowing how to get rid of ant hills in the yard. However, not all ant hills look the same. Let’s go over the types of ant hills you may encounter in your yard or on your property.
You may have ant hills in your yard if you find:
Mounds of “Fluffy” Looking Dirt Or Soil With A Hole In The Top Center
The types of ant hills most of us are familiar with when looking for how to get rid of ant hills in the yard are the hills or mounds of fluffy looking or turned sand or soil. This soil will be a fairly distinctive hill shape with a small hole in the top where ants come and go.
These hills are typically the easiest to identify and pinpoint, as they are often surrounded by an accumulation of ants.
Small Handfuls Of Soil or Dirt That Are Shapeless
Other ant hills are not as obvious as the above. In fact, some can look like smaller scoops of dirt or soil on the surface of the ground. They may be shapeless or have small holes in numerous locations where ants enter.
Piles of Pine Needles, Dead Leaves, Or Other Debris
Ants can also make ant hills below piles of debris like pine needles, leaf litter and grass clippings that go uncleared.
These ant hills are more common in larger expanses of fields or lawns where landscaping is less tidy.
Stones Or Trees
Some species of ants don’t create ant hills specifically in the dirt, but their presence on your property can still be just as concerning and spread just as rapidly. In fact, some species of ants build ant hills or colonies inside hollowed trees and beneath stones.
Why Do I Have Ant Hills In My Yard?
Ants are attracted to food sources like insects and sugars.
Like most insects, ants are on the hunt for a good place to live. They are seeking the ideal combination of a good food source and safe habitat.
The ideal lawn for ants is one that is dry, unhealthy, and easy to dig into. However, the first thing that typically attracts ants to a yard is going to be an ideal food source. Ants are attracted to sweet foods, including sweet smelling flowers and many other types of plants. Aphids in your garden can also increase your chances of dealing with ants, as aphids secrete a sweet substance called honeydew, which ants love.
Ants will avoid building ant hills in busy areas around the lawn, and will often stick to the outskirts of your property. However, if your property is quite large or relatively undisturbed most of the time, ant hills can crop up anywhere.
As we mentioned above, one or two ant hills in your yard are not usually an issue, and many experts even recommend leaving them alone and reaping the natural benefits that ensue. However, large numbers of ant hills can be quite damaging.

How To Get Rid Of Ant Hills In the Yard and Keep Them From Returning
A healthy lawn has less likelihood of becoming infested with ant hills and other pests.
Unfortunately, it can be difficult to keep ants and their ant hills off your property 100% of the time. The good news is that, in small numbers, both ants and ant hills can be beneficial to your yard.
You can help control ants without completely eliminating them by following the below ant-repellent tips and tricks.
Keep Your Lawn Healthy
A healthy lawn is much less likely to suffer from pest infestations like ants and ant hills. In fact, lawns that are lush and well covered by grass are not ideal for ants who build ant hills. You can also keep up with your landscaping and use cedar mulch instead of traditional mulch to repel ants and other pests.
Remove Excess Debris Around Your Yard
Removing debris from around your property is one way you can work on how to get rid of ant hills in the yard. However, keeping your yard tidy and free of debris can keep these pests from returning in the future.
Reduce debris around your property like dead trees, leaf debris and tree branches. It also helps to remove unnecessary clutter like buckets, used tires, gardening tools, etc.
Pick Up Fallen Fruits From Surrounding Fruit Trees
Ants are attracted to sweet food sources, and fruits from surrounding trees will not only attract ants that could result in ant hills, but other pests as well. Pick up fallen fruits as often as possible to avoid dealing with ants as well as pests like fleas, gnats, raccoons and rodents.
Control Rid Of Aphids and Other Garden Pests
Ants not only eat sweets but also feed on other insects. Pests like aphids and lawn grubs can supply a tasty meal to ant colonies. As you work on how to get rid of ant hills in the yard you should also work to remove other garden and lawn pests as well.
Plant Ant-Repellent Plants
Companion planting ant-repellent plants in your yard and around the perimeter of your home is a great way to protect your property from ants and their ant mounds year-round. Some of the best ant repellent plants include garlic, mint, lavender, rosemary, tansy, thyme, marigolds, lemongrass, catnip, peppermint, garden mint, pennyroyal, and common yarrow plants.
Of course, we always suggest doing research before companion planting in your garden or yard to keep pests away. Some common plants that work as pest repellents are also toxic to dogs and cats, so keep this in mind if you have pets who frequently play in your yard.
Keep Outdoor Garbage Bins Sealed and Stored Securely
Many pests are attracted to garbage, and ants are no exception. To help keep them from being attracted to your yard or property, we suggest keeping your outdoor garbage bins properly sealed and stored until trash day.
Use A Quality Pest Control Regiment Year-Round
Last but not least, we always suggest practicing a quality pest control regiment that can protect your home and yard from ants and other pests all year-round.
Whether you use natural products, home remedies, insecticides or professionals, protecting your home from pests not only saves you money in the long run, but also helps to keep your property looking it’s best and your family and loved ones safe and healthy.
