Are you wondering how to get rid of fire ants?
If you live in the southern part of the United States, chances are you just might be. These troublesome (and sometimes dangerous) stinging pests can live in large colonies of up to 250,000 ants and are increasingly causing problems for many homeowners.
These insects reproduce and spread quickly, and can wreak havoc on lawns, gardens, buildings, and in homes, leading many to not only question how to get rid of fire ants, but how to prevent them as well.
And while fire ants are beneficial insects and play an important role in our ecosystem, these creatures are also an invasive species to North America and have been a growing nuisance since they were first accidentally introduced into Alabama in the 1930’s.
So, if you’re here looking for how to get rid of fire ants on your property or around your home, we’re here to help.
Let’s get started.
What Are Fire Ants?
There are several species of fire ants in the US but the red imported fire ant is the most problematic.
“Fire ant” is the general term used to describe over 200 species of stinging ants who are native to South America. Some of these species of fire ant found their way to North America via human travel in the 1930’s.
Fire ants are not always red or brown in color, as often thought. In fact, there are two types of fire ants that are now common in North America that are both black and red, including the black imported fire ant and the red imported fire ant.
The most common and most problematic fire ant in the United States today is the red imported fire ant, which has been known to build large, mound-like colonies in flat fields and yards.They prefer to live outdoors but can find their way inside our homes in search of food.
It’s important to know how to get rid of fire ants not only because they make such large colonies, but also because they can be hazardous. Fire ants have been known to be mysteriously attracted to electrical currents and are often found nesting in electrical junction boxes. Because of this, they can cause serious damage to homes and buildings. Their large colonies can also destroy lawns, plants, and gardens.
Worse, fire ants can be dangerous. They are territorial and aggressive insects who kill prey using their strong mandibles to hold them while injecting a venom using a stinger in their abdomen.
The fire ant’s sting releases a toxin called solenopsin, which is a poisonous alkaloid they use to not only kill other insects, but also to attack anyone or anything they see as a threat to their colony.
While a fire ant sting is typically not dangerous to humans and pets, it can be fatal if the victim has an allergic reaction known as anaphylaxis.
Due to the damage fire ants can cause and their potential danger to humans and pets, it’s important to be able to recognize if you have a fire ant infestation and know how to get rid of fire ants quickly and effectively.
How To Get Rid Of Fire Ants – Recognizing A Fire Ant Infestation
Fire ants cause damage to buildings, homes, food, electrical junction boxes and more.
Because fire ants reproduce so quickly and are known to expand and develop large colonies in yards (and sometimes buildings and homes), it’s vital you recognize the first signs of a fire ant problem around your property so you can keep these invasive insects under control.
The easiest way to recognize a fire ant problem is to keep an eye out for a fire ant mound. The unique formation of a fire ant mound is unlike other ant hills, as it doesn’t have an entry at the top of the hill. Instead, a fire ant mound looks like a pile of “fluffy” dirt or soil. When disturbed, a swarm of fire ants will usually rush out to defend their colony and queen.
Unless you have a large fire ant infestation in your yard, you may not notice a mound right away, and may not realize you have a problem until you see them inside your home or until you are stung.
If you want to know how to get rid of fire ants, keep an eye out for other common signs of their presence, including:
- Seeing fire ants in your yard or home
- Finding a fire ant mound or mounds in your yard or near your property after rainfall
- A repeated swarm of fire ants arriving when you leave out food
How To Get Rid Of Fire Ants – Most Popular Methods
Fire ants can be eliminated using a few different methods.
Fire ants can be difficult to get rid of because they reproduce so rapidly and often build large colonies underground. Some colonies extend as far as 25 feet away from the entrance and a colony of fire ants can be as vast as 250,000. Sometimes when a colony gets too full, fire ants will venture out to build new mounds and colonies nearby.

Fast Facts – Everything You Should Know About Fire Ants
Fire ant mounds do not have entry holes at the top, like many other ant mounds.
Yes, fire ants are an invasive insect to North America with a painful and venomous sting. And yes, they can damage property in large numbers and even be dangerous to sensitive people and pets. However, it’s important to remember that they, like most creatures, play an important and vital role in our ecosystem.
Fire ants, like many different ant species, help aerate the soil, thus encouraging healthy plant life. They also eat other problematic pests and insects, as well as provide an important food source to predators like birds.
Let’s take this time to learn a few facts about fire ants you may not have known.
Fire Ants Are Omnivores
Fire ants eat both meat and vegetation. They hunt for their food and primarily feed on insects like spiders, earthworms, ticks, arthropod eggs, as well as fruits, vegetables, sweets, and even dead animals.
Fire Ant Mounds Don’t Have Entry Or Exit Holes
Most ant mounds have an entry and exit hole at the top of the dirt. Fire ants, on the other hand, make their entry and exit points on the ground. If you find a large mound of dirt without an entry and exit point, you’ve likely spotted a fire ant mound.
There Are Over 200 Species of Fire Ants
That said, the two most common types of fire ants you will come across in the US are the imported black fire ant and the imported red fire ant.
Fire Ants Are More Aggressive Than Other Ant Species
Named for their painful, burning sting, red fire ants are known to be more aggressive than other ant species. They hold onto their victims using strong mandibles and then sting from a stinger in their abdomen. They often sting repeatedly, injecting a toxic venom that kills smaller prey.
There Are Three Types Of Ants in A Fire Ant Colony
The three different ants include the queen, drone ants (males) and worker ants (primarily females).
How To Prevent Future Fire Ant Problems On Your Property
Prevention is the easiest way to keep fire ants from becoming a problem.
The best method for how to get rid of fire ants is to prevent them from becoming a problem in the first place.
There are several ways you can help prevent fire ants from building colonies in your yard and subsequently invading your home by following the below preventative methods:
- Eliminate the food source
Remember, fire ants are omnivores who feed on a number of different food sources. This means your food sources could be theirs. Pick up after picnics and don’t leave ripe fruits or veggies on trees or in gardens. You may also choose to use natural pest control methods often to help eliminate other insects fire ants feed on.
- Turn mulch and soil often
Fire ants don’t want to build their nests in areas that are often being disturbed by humans. To help disrupt colonies that are in the process of being built and avoid future fire ants from building near your property, turn mulch often.
- Keep up on yard maintenance
Mow your lawn and keep it tidy. Doing this will not only help you work on how to get rid of fire ants, but it will also help keep other pests from infiltrating your lawn like snakes, insects, and rodents.
- Trim trees and shrubbery
Fire ants often get into our homes through trees and shrubs that are touching our property. Trim branches and bushes back and plant vegetation at least a foot away from the perimeter of your home.
- Keep garbage stored securely until trash day
Like many ants, fire ants are attracted to the scent of garbage and old food. Store garbage in airtight containers or off of your property if possible, and don’t leave it out until it’s time for the trash to be removed. This will also help eliminate other pests like raccoons and possums.
- Wash empty garbage bins with ammonia
Ammonia will help cover the scent of food, sweets, and other garbage that may attract fire ants. Spray your garbage cans down with ammonia and water spray after they are emptied and as often as needed to help keep fire ants and other pests away.
And remember, fire ants may be an invasive nuisance but they can also be beneficial. Controlling fire ants is key to keeping them from becoming problematic in your yard, garden, or home.
