It rained hard overnight. In the morning there are three new mounds of loose dirt in the lawn — one right next to the swing set. Later your kid comes in crying with red welts on their ankle, or your dog won’t stop licking its paw.
That’s fire ants. Here’s how to recognize them, keep your family safe, and get rid of the colony instead of just moving it.
How to recognize fire ants
Fire ants are small reddish-brown ants, and in South Florida they’re one of the most common ants in lawns, swales, and along driveways. The easiest way to spot them is the mound:
- Loose, fluffy dirt piled up in the grass, along sidewalks, or against the house or a fence
- No obvious hole on top — the ants enter and exit through underground tunnels
- Mounds appear or grow after rain, when the colony pushes its nest higher to escape wet soil
- Ants pour out fast when the mound is disturbed, and they climb up whatever touched it
Other ants make small piles of soil too. The difference is the reaction: disturb a fire ant mound and you’ll see a swarm of aggressive ants within seconds.
Why fire ant stings hurt so much
A fire ant grabs on with its jaws and stings, often more than once, and many ants sting at the same time. That’s why a kid who steps on a mound ends up with a cluster of stings, not just one.
What people usually notice:
- A burning pain right away, then itching
- Red, raised bumps
- Small white pustules that often form within a day or so
Most stings are just painful and annoying. But some people — and some pets — have stronger allergic reactions. If anyone has trouble breathing, swelling of the face or throat, or feels dizzy or faint after being stung, call 911. If you’re worried about a reaction, get medical help. For pets, call your vet.
Keep kids and pets away from mounds
Until the colony is gone, a few habits go a long way:
- Walk the yard before kids play. Look for fresh mounds, especially after rain and around play areas.
- Put shoes and socks on for anyone playing in the grass.
- Keep pets on a leash or watch them in areas where you’ve seen mounds. Dogs tend to sniff and dig right into them.
- Don’t let kids poke mounds with sticks. Teach them that a pile of loose dirt means “stay away.”
- Check before you sit down on the lawn, on a curb, or in a swale.
- Move pet food and water bowls away from mounds, and don’t leave food outside.
Why kicking or flooding the mound backfires
It’s tempting to stomp on a mound, rake it flat, or run the hose into it. The problem is that the mound is just the top of the nest. The colony — and the queen — can be well below the surface.
When you disturb it:
- The colony moves. Ants relocate the queen and the brood a short distance away, and a new mound shows up nearby — sometimes closer to the house.
- You get stung. Disturbing a mound is exactly what triggers a mass attack.
- Flooding doesn’t drown them. Fire ants are built for wet ground. Water mostly makes them move.
Why store-bought products can make it worse
Granules and sprays from the store can kill the ants they touch, but that’s usually only the workers on the surface. Many South Florida ant species react to that stress by moving or splitting into more colonies. One mound in the middle of the yard can turn into several along the fence line.
The goal isn’t to kill the ants you see. It’s to eliminate the colony, and that means reaching the queen.
Large lots and swales
Fire ants love open, sunny ground, which is why big properties get hit hard. If you’re on a large lot in Homestead or anywhere with acreage, you may have mounds scattered across the property, along the fence, and around sheds and equipment.
Swales — the grassy strip between the sidewalk and the street — are another favorite spot. They get sun, they collect rain, and they’re right where kids get off the bus and dogs go for walks.
On a big or open property, treating one mound at a time rarely keeps up. Colonies you haven’t found yet keep growing while you deal with the ones you can see.
How Golden treats fire ants
Our licensed technicians start by identifying the species, because not every ant in the yard is a fire ant and each one responds differently. Then we use bait that worker ants carry back to the nest, together with a targeted spray, so the treatment reaches the colony — not just the ants on top of the mound. We treat fire ants across large lots too.
For regular treatments you, your kids, and your pets can stay home. If an aerosol or fogger is ever needed, everyone including pets needs to be out for 2 hours. We use EPA-registered products and we’re licensed in Florida for general household pest control and lawn & ornamental (FDACS #JB288307).
The inspection is free, and you get a price before any work starts. We’re open 6am to 7pm every day, with no extra charge on weekends and same-day service in most of Miami-Dade and Broward. See our pricing or contact us to book — before the next rain brings up more mounds.
