Ant Hills in Florida: Types and How to Get Rid of Them

The best way to deal with ant hills in Florida is by targeting the colony’s queen using species-specific bait treatments, especially granular baits for fire ants. This method helps eliminate the entire nest rather than just scattering the surface workers.

Ant hills are more than just unsightly patches of dirt.

They’re the tip of an underground iceberg, complex colonies housing thousands of ants with their queen deep inside, constantly expanding.

And in Florida’s warm, humid climate? They thrive year-round.

From cracked sidewalks in Coral Springs to garden beds in Parkland, they pop up fast and stick around unless you know exactly what you’re doing.

That’s why understanding ant hills is the first step toward getting your property back. This guide will tell you all you need to know about them.

Let’s begin with what these dirt domes really are and why they love Florida’s soil so much.

What Are Ant Hills and Why Do They Appear in Florida?

Step outside in Florida after a good rain and chances are, you’ll spot it, another one. A crumbly little dome of dirt right in the middle of your lawn. Maybe it popped up overnight. Maybe it’s been there for weeks, growing like a tiny volcano. Either way, it’s official: you’ve got an ant hill.

But here’s the thing, what you see on the surface is just the beginning.

It’s Not Just a Pile of Dirt

That mound is the front door to a full-blown underground colony. Beneath your feet is an entire ant city: tunnels twisting and turning in every direction, rooms for baby ants, food pantries, escape routes, and one very well-protected queen calling the shots.

And the mound up top? That’s not random. Ants build it for two big reasons:

• To protect the nest from predators and weather.

• To act like a natural thermostat, keeping the inside cool, dry, and just right for the colony to thrive.

Honestly, if ants had Pinterest boards, they'd be full of mound designs.

Why Florida Is Ant Paradise

Now, let’s talk about why these hills are everywhere in Florida. For ants, our state is a five-star resort:

• Soft, sandy soil (easy digging)

• Warm weather nearly all year (no hibernation needed)

• Afternoon thunderstorms like clockwork (hello, freshly moistened construction sites)

And because our winters are more “light jacket” than “freeze warning,” ants don’t take a season off. They just keep growing, digging, and multiplying.

Step-by-Step: How Ant Hills Are Built

1. Excavation Begins: Worker ants remove soil grain by grain, pushing it to the surface like little bulldozers. The dirt they carry out becomes the hill you see above ground.

2. Tunnel Networks Take Shape: Beneath the surface, ants dig a network of tunnels and chambers, nurseries for the young, food storage areas, and escape routes in case of danger.

3. Mound Becomes a Fortress: The mound on top isn’t just a byproduct. It helps regulate air flow, temperature, and moisture inside the nest. Think of it like a natural HVAC system, custom-built for Florida’s hot, sticky climate.

4. Satellite Colonies Emerge: As the colony grows, some species (like ghost ants and fire ants) create satellite nests nearby. These act like expansions of the main colony, think suburbs for ants.

Common Ant Types That Build Ant Hills

Not all ant hills are created equal, and neither are the ants behind them.

If you want to know what you're up against, it helps to know who built the mound in the first place.

Florida is home to several ant species that build (or cleverly avoid building) hills, each with their own behaviors, risks, and quirks. Let’s get to know the usual suspects:

1. Fire Ants – The Red Menace

These are the infamous ones. If you’ve been stung before, you probably remember it, sharp, burning, and followed by itchy white pustules. Fire ants are aggressive defenders of their mound and will swarm anything that disturbs it, including children and pets.

Their hills are easy to spot:

• Dome-shaped

• No visible entrance

• Usually in open, sunny areas like lawns, driveways, or garden beds

Fire ant colonies often contain multiple queens, which makes them tougher to eliminate. Treating them improperly can just make them spread to new areas of your yard.

They're also known for nesting near electrical equipment and AC units.

2. Ghost Ants – The Invisible Intruders

Don’t expect a classic ant hill with these ants. Ghost ants are tiny, love sweet foods, and build hidden nests in moist, warm areas. You’ll find them:

• Behind baseboards

• Inside electrical outlets

• Under bathroom sinks

They don’t sting, but they invade quickly and can split into sub-colonies when threatened.

If you see a trail of ants in your kitchen and they smell like coconut when crushed, you’re likely dealing with ghost ants.

3. Carpenter Ants – The Silent Destroyers

Carpenter ants don’t build hills. Instead, they tunnel through wet, rotting wood, making them a major structural threat. If you’re finding sawdust-like shavings around windows, door frames, or old tree stumps, take notice.

They’re most active at night and prefer homes with moisture problems. They don’t sting, but their large jaws can bite if handled.

4. Argentine Ants – The Colony That Never Ends

These ants don’t build traditional mounds, but don’t underestimate them, they form super-colonies. That means thousands upon thousands of ants across multiple nests, all working together like a single massive unit.

You’ll find their shallow nests near:

• Foundation edges

• Planters

• Irrigation systems

They’re not aggressive, but they spread bacteria, protect plant-damaging pests like aphids, and are tough to manage without professional help.

5. Pavement Ants – Crumb Collectors in the Cracks

Small but persistent, pavement ants build dirt mounds between sidewalk cracks, along driveways, and around patios. They’re not particularly dangerous, but they’ll find their way inside for crumbs, sweets, and grease.

They can bite, but it’s rarely serious. Still, if you’ve got kids crawling around those cracks, it's one more reason to deal with them quickly.

So now you understand the culprits and how their existence can be dangerous at times. Let’s now learn more about ant settlements.

Where You Can Find Ant Hills In Florida

In Florida, ants aren’t picky. They’ll build wherever the conditions are right. Let’s look at where these mounds (and their hidden cousins) tend to show up, and why.

1. The Usual Suspects: Lawns, Gardens, and Sidewalk Cracks

Start with the classics. If you’ve got:

• A well-irrigated lawn

• Flower beds with fresh mulch

• Cracks between pavers or sidewalks

...you’ve got prime real estate for ant hills. Why? Moisture and warmth. Florida soil is naturally sandy and loose, which makes it easy for ants to dig.

2. The “Oh No” Zones: Hidden Spots Around the House

Some ant hills don't look like hills at all. You may not see the mound, but that doesn’t mean you’re in the clear. Check these sneakier locations:

• Underneath AC units: The heat from compressors creates a warm, dry shelter, perfect for nesting.

• Behind retaining walls: These structures offer shade, moisture, and structural protection all in one.

• Near leaky sprinkler heads or hoses: Constant moisture draws in ants like a buffet.

If these areas are regularly damp or sunny, ants will zero in.

3. Inside the Home: When Hills Go Stealth Mode

Some ant species, like ghost ants, don’t bother with traditional outdoor mounds. Instead, they set up shop inside your house.

That’s right, your bathroom tiles, baseboards, kitchen cabinets, even the hollow rods of your shower curtain can become a nesting site. Ghost ants especially love:

• Bathrooms (they crave moisture)

• Gaps in wooden floors

• Wall voids near plumbing

And you won’t always see a single pile of dirt. Their colonies are fractured into mini-units across several hideouts which makes them so hard to eliminate.

So whether you're spotting domes in your grass or wondering why ants keep showing up near the sink, know this: they’ve likely found a place that’s cool, damp, and protected.

Now, let’s break down which types of ants you’re most likely dealing with here in Florida, and how their hills (or lack of them) can give them away.

It’s time to learn to keep them away. And if need be, call in the pros so you don’t face unfortunate consequences.

Ant Attractants & How Preventive Measures To Keep Them Away

If you’re seeing ant hills in your yard, there’s a reason, and it’s probably not just “bad luck.”

Ants build where the conditions are right, and many Florida properties unintentionally roll out the welcome mat.

Let’s break down what’s attracting them and what you can do to stop them, permanently.

What’s Drawing Ants to Your Property?

1. Moisture is one of the biggest culprits. Ants are drawn to damp environments. Leaky spigots, broken sprinkler heads, standing water, and even clogged gutters can all make your soil too attractive to resist.

2. Food is the next major draw. If you leave out pet bowls, have a compost pile, or drop fruit from backyard trees, ants will find it, fast. Even a sugary drink spilled near a patio can lead to a trail back to a nest.

3. Soil Type matters, too. Florida’s sandy, well-drained soil is practically made for tunneling. Loose dirt lets ants build extensive networks with minimal resistance.

4. Shelter also plays a role. Dense vegetation, thick mulch, sidewalk cracks, and even the warm area around your AC unit create cozy, shaded nesting spots that feel secure from predators and weather.

And here’s a little-known detail: fire ants are particularly attracted to disturbed or sun-warmed ground.

Just finished a landscaping project? That fresh soil is exactly where they want to be.

How to Keep Ant Hills from Coming Back

You don’t just want to get rid of ant hills, you want to make sure they stay gone. Here's how:

1. Eliminate Attractants: Start by cutting off what ants came for. Dry out soggy patches, clean up food waste, and store outdoor trash properly. Remove clutter that gives ants places to hide.

2. Improve Drainage: Fix leaks around faucets and irrigation systems. Consider switching to drip irrigation, which provides water to plants without soaking the soil. Raise garden beds to reduce lingering moisture.

3. Care for Your Lawn: Strong grass helps crowd out colonies. Regular dethatching, aeration, and fertilization keep your lawn healthy, and far less welcoming to pests.

4. Set Up Barriers: Seal cracks in pavement, sidewalks, and your home’s foundation. Use pet-safe perimeter treatments around high-risk zones like mulch beds and patios to keep ants from crossing the line.

5. Schedule Regular Inspections: The best prevention is proactive. At Hoffer Pest Solutions, we offer seasonal treatments and inspections tailored to Florida homes. We know where ants like to hide, and how to stop them before they ever build that first hill.

Ant hills are easy to miss in the beginning, but the sooner you make your yard less appealing, the easier it is to keep your lawn safe, your kids and pets protected, and your home ant-free.
