Fire ants are more than just a backyard nuisance—they’re aggressive, invasive, and armed with a painful sting that can harm both people and pets. If you’ve ever stepped on a mound barefoot, you know how important it is to keep these pests out of your yard.
In this guide, we’ll walk you through where fire ants live in the U.S., how to identify them, and what you can do to protect your home and yard from their destructive colonies.
Fire ants belong to the Solenopsis genus and are known for their aggressive behavior, especially when their nest is disturbed. Unlike common house ants, fire ants are reddish-brown with darker abdomens and have two distinct nodes between their thorax and abdomen. Their antennae are elbowed, and they range in size from 1/8 to 1/4 inch depending on their role in the colony.
While people often refer to them as “red ants,” it’s important to note: not all red ants are fire ants. True fire ants are known not just for their color but for their vicious sting and rapid territorial expansion.
Fire ants thrive in warm, sunny environments with mild winters—making the southern U.S. their ideal habitat. They are especially prevalent in:
Their range continues to expand, with sightings as far west as California and northward into parts of Tennessee and Kentucky. They’re even spreading into areas like Virginia where the winters have become milder.
Wherever the conditions are right – sunny, moist soil and limited frost, fire ants can move in fast and stay for good.
Fire ants build large, dome-shaped mounds in sunny, open areas. You’ll often find them in:
But don’t be fooled—the visible mound is just the tip of the iceberg. Fire ant colonies can tunnel far underground, with complex networks that make them hard to eliminate. In wetter environments, fire ants have been known to form floating rafts during floods to protect their queen and survive.
They’re also highly adaptive. If outdoor conditions aren’t ideal, fire ants may nest inside walls, under floorboards, or in rotting wood, making indoor infestations possible.
Many homeowners confuse “red ants” with fire ants, but “red ant” is a general term. Not all red ants are aggressive or dangerous.
Here’s how to tell if you’re dealing with fire ants:
If you’re unsure, it’s best to call a professional for identification and next steps.
Both – and it’s what makes them so dangerous. Fire ants first bite to grip the skin, then rotate their bodies to sting multiple times.
Their sting injects a venom called solenopsin, which causes:
Fire ant stings are more than just irritating—they can be dangerous, especially to children, pets, or anyone with known allergies.
In short—yes.
While fire ants play a role in the ecosystem, their presence in residential areas poses real risks:
Ignoring a colony allows it to grow—and once it’s large enough, control becomes much more difficult. Early management is the key to protecting your property and your peace of mind.
You can take a two-step approach to fire ant control: eliminate current mounds and prevent future infestations.
Use fire ant bait or targeted insecticide to reach the queen and destroy the colony. Apply in the morning or evening when ants are foraging. Avoid disturbing the mound before treatment—this could cause the colony to relocate.
After treatment, reduce the likelihood of a comeback by:
Fire ants are most active when the soil is warm and moist—so it’s a smart idea to schedule seasonal inspections to catch any new colonies before they grow.
For larger infestations or recurring problems, professional pest control is often the most efficient (and safest) solution.
Fire ants are aggressive, invasive, and unfortunately, very common in warm states like Florida, Texas, and Georgia. Knowing where they live and how they behave is your first defense against a full-blown infestation.
Here’s a quick recap:
If fire ants have made your home or yard their own, don’t wait for the problem to spread. Mira Pest offers local expertise and safe, proven fire ant control methods for homes and properties of all sizes.
