Most people think of ants as a nuisance, not a threat. They crawl across countertops, get into the pantry, and sometimes build mounds in the yard. But do ants bite? The short answer is yes.
Depending on the type, it can be more than just a little pinch.
In this post, we’ll walk through which ants are known to bite (or sting), how they behave in different parts of the country, and what to do if you start noticing them inside your home.
Do Ants Bite or Sting? Here’s the Difference
First, a quick clarification: generally, ants can bite. Not all ants bite, and not all bites are the same.
Some ants use their jaws to bite and then spray formic acid into the wound, which causes irritation. Others sting instead of bite, injecting venom through a stinger like a wasp.
In either case, the result can range from mild redness to painful welts or allergic reactions. The severity depends on the species, the size of the colony, and your body’s sensitivity.
Ants That Bite in the Southern U.S.
If you live in Georgia or anywhere in the Southeast, you’re likely to run into a few of these biting or stinging species:
1. Fire Ants
Easily the most aggressive ant in the region, fire ants both bite and sting. They latch on with their jaws and then sting multiple times in quick bursts, injecting venom that causes painful, burning welts.
In some cases, this can lead to allergic reactions or even hospitalization.
Fire ants are common throughout Georgia and thrive in sunny areas like lawns, sidewalks, and driveways.
2. Carpenter Ants
These ants are known more for damaging wood than biting humans, but they will bite if disturbed. Their bites are strong enough to break the skin and may cause a sharp pinch.
Carpenter ants are often found near decaying wood, tree stumps, or inside walls with moisture problems.
3. Rover Ants
These ants are not aggressive and rarely bite, but they’re worth mentioning because they’re becoming more common in Georgia homes.
They’re often confused with fire ants due to their size, but they don’t pose the same threat.
Ants That Bite in Other Regions
Biting ant species vary across the U.S. Here are a few to watch for depending on where you live or travel:
Western U.S. (Harvester Ants)
Found mostly in dry, sandy regions, harvester ants can bite and sting. Their sting is known to be quite painful and may cause swelling.
Unlike fire ants, they’re less likely to attack unless provoked.
Midwest and Northeast (Pavement Ants)
These small brown ants are mostly nuisance pests, but they can bite when defending their colony. The bites are mild and usually harmless, but large infestations inside homes can still cause frustration.
Southwest (Argentine Ants)
Common in California and surrounding states, these ants don’t bite aggressively. However, their massive colonies make them hard to control.
They don’t sting but can outcompete native ant species and invade kitchens or bathrooms in large numbers.
What Do Ant Bites Look Like?
Most ant bites or stings look like small red bumps. In mild cases, the area may be itchy or slightly swollen. Fire ant stings are more severe and often form white pustules within 24 hours.
Watch for:
- Red, raised bumps or blisters
- Itching or burning
- Localized swelling
- Dizziness, trouble breathing, or rash in rare cases (seek medical attention)
If you’re unsure what caused the bite, monitor the area and avoid scratching. Use topical creams, cold compresses, or antihistamines to relieve symptoms.
How to Tell If You Have a Problem Indoors
A few stray ants are normal. But if you’re seeing ants every day, especially in the kitchen or bathroom, there may be a colony nearby.
Signs of an indoor infestation include:
- Ant trails along walls, windowsills, or countertops
- Sawdust or fine debris that may point to carpenter ants
- Tiny holes in food packaging
- Ants appearing from vents, outlets, or baseboards
Ants often enter homes looking for food and water. Even small spills or damp areas can attract them. Once they find a reliable source, they leave behind a scent trail for others to follow.
Why Ant Type Matters for Treatment
Different ants require different treatment strategies. Fire ants in the yard should be handled with caution, often using bait and professional-grade products to eliminate the colony.
Carpenter ants may signal a moisture issue or even structural damage inside the home.
That’s why proper identification is step one. Store-bought ant spray may kill the ants you see, but it won’t solve the root problem.
In some cases, spraying can cause the colony to split and spread further, making the problem worse.
Preventing Ant Bites and Infestations
You can lower your risk of both bites and infestations by taking these simple steps:
- Keep food sealed and clean up crumbs or spills quickly
- Fix leaky pipes and eliminate standing water
- Seal cracks around windows, doors, and the foundation
- Trim bushes and tree branches that touch your home
- Avoid disturbing visible mounds in your yard
If you have children or pets who play outdoors, be extra careful around ant mounds. Fire ants can swarm quickly if disturbed, delivering dozens of stings within seconds.
