Fire ants can turn a normal afternoon in your yard into a painful experience. Disturbing a mound often results in multiple stings that cause a burning sensation and leave white pustules. In some cases, stings can also trigger allergic reactions or even anaphylaxis.
Understanding where fire ants live and how their colonies grow can help you avoid encounters with them. Red imported fire ants thrive in warm climates across the Southeast, including Chattanooga.Â
If mounds keep appearing or spreading across your yard, professional pest control in Chattanooga may be the best way to stop the problem.
Key Takeaways
- Fire ants prefer sunny areas with loose, moist soil.
- Fire ant colonies may have a single queen or multiple queens.
- Fire ant stings cause a painful sting, a burning sensation, and often a pustule.
- Professional pest control services can treat active fire ant colonies and help reduce the likelihood of new infestations.
Where Fire Ants Live
If you want to get rid of fire ants, you need to know where they live. Knowing where fire ants build nests helps you find colonies faster and treat them more effectively.
Lawns and Open Sunny Areas
Fire ants prefer sunny areas with well-drained soil. That is why mounds often appear in open lawns, school fields, parks, and along sidewalks in Chattanooga neighborhoods.
Unlike a harvester ant, which clears vegetation around its nest, fire ant mounds look like dome-shaped piles of loose, reddish-brown soil. There is usually no visible hole at the top. Beneath the mound are complex underground tunnels. These tunnels protect worker ants, larvae, pupae, and the queen.
Landscaping and Garden Beds
Mulch beds and flower gardens are also common nesting spots. These areas stay warm and moist, which fire ants prefer. They search constantly for food sources such as insects, proteins, seeds, and sugary substances.
If you water your lawn regularly or have irrigation lines, you may create ideal conditions for fire ants without realizing it. Many homeowners first notice red ants moving in trails toward a food source near plants or outdoor trash bins.
Near Foundations and Structures
Fire ants often build nests near driveways, patios, and home foundations. They also look for warm, protected spaces that offer shelter from the weather and disturbance. According to the Texas Cooperative Extension, fire ants can nest inside electrical housing year-round, which sometimes leads them into electrical boxes or outdoor equipment.
It is now common across Tennessee and other southern states, including Georgia, South Carolina, North Carolina, Arkansas, Louisiana, and Oklahoma, where fire ant populations continue to expand.
Because fire ants build extensive underground tunnels, the visible mound may only be a small part of a much larger system below the surface.
How to Find the Fire Ant Nest
To kill fire ants successfully, you must locate the active nest. Fire ant colonies can contain thousands of worker ants and expand quickly if left untreated.
Look for Fresh Fire Ant Mounds
The easiest way to identify fire ants is by spotting new fire ant mounds. These mounds can appear almost overnight, especially after rain.
If you gently disturb a mound, worker ants will rush out aggressively. This rapid response is a key trait of this species of fire ant and often results in fire ant stings.
Watch for Swarmers
In spring and summer, winged males and females leave the colony to mate. After mating, the male dies, and the fertilized queen lands, sheds her wings, and burrows into the soil to start a new colony.
Some colonies have a single queen, while others have multiple queens. Colonies with multiple queens spread faster and are harder to control.Â
Swarming often occurs a day or two after rain, according to research documented by Alabama A&M University and Auburn University.Â
Follow Ant Trails
Worker ants travel along clear paths between the mound and a food source. You may see them carrying insects or small food particles back to the nest. Following these trails can help you find hidden fire ant mounds behind shrubs, fences, or landscape borders.
How to Stop the Colony
Flattening a mound will not stop fire ants. If the queen survives, the colony will rebuild. Here are some proven methods you can try to get rid of fire ants:
Bait Treatments
Bait treatments attract worker ants, which carry the bait back to the colony. The goal is to reach the queen and stop reproduction.
Many over-the-counter treatments target foraging ants as they gather food. These products use active ingredients designed to disrupt the colony and reach the queen.
When used as directed on the label, these treatments may help reduce the size of a fire ant colony. However, improper application may cause the colony to split or move to another area.
Broadcast Treatments Across the Yard
If you have multiple fire ant mounds, spot treatment may not be enough. Broadcast treatments help reach both visible and hidden colonies, which is often best handled by a pest control professional.
Our annual Fire Ant Treatment is a water-activated application designed to eliminate active fire ant colonies and prevent new mounds from forming for up to 365 days. This approach can be effective for properties with multiple fire ant mounds across the yard.
Biological Control and Natural Enemies
Researchers from the U.S. Department of Agriculture (USDA ARS) have studied biological control methods using natural enemies from South America, introducing certain parasitic phorid flies and pathogens in limited areas to help reduce fire ant populations.
Researchers have also tested biological control programs in Australia and parts of the southern United States. While helpful in some regions, biological control alone rarely eliminates a residential infestation.
When to Call a Pro in Chattanooga
Some fire ant infestations require professional help.
New mounds keep appearing
If you treat one mound and several more appear, you may be dealing with connected fire ant colonies. Colonies with multiple queens can expand quickly across a yard.
A pest professional can inspect the property, identify active fire ant colonies, and apply treatments designed to target the infestation.
Severe reactions to fire ant stings
Most fire ant stings cause a painful, burning sensation followed by a pustule. However, some people experience allergic reactions. In rare cases, anaphylaxis can occur and requires immediate medical attention.
If someone in your home has had a severe reaction to fire ant stings, reducing exposure becomes even more urgent.
Large or ongoing infestation
If fire ants have taken over play areas, gardens, or high-traffic areas, it may be time to call in a professional pest control company. Our Year-Round Pest Prevention service helps manage a wide range of pests and reduces the risk of recurring infestations.

FAQs
How can I tell fire ants apart from other ant species?
Fire ants are reddish-brown with elbowed antennae and a narrow waist. Their fire ant mounds are dome-shaped and usually lack a visible opening at the top. They also respond aggressively when disturbed.
Are store-bought fire ant treatments enough to eliminate a colony?
Some store-bought bait or mound treatments can reduce small fire ant infestations. However, if the treatment does not reach the queen, the colony will survive and rebuild. Larger or recurring infestations often require professional pest control to eliminate the entire colony.
Do fire ants die in winter in Tennessee?
Fire ants become less active in cold weather but survive underground. Fire ant colonies remain active and survive when soil temperatures rise in spring.
