That loose mound of soil in your Plantation lawn isn’t harmless — it’s likely a colony of red imported fire ants, the most aggressive stinging insect in South Florida. Here’s why they’re genuinely dangerous and what to do before someone in your family gets stung.
Fire Ants at a Glance
- Species: Red imported fire ant (Solenopsis invicta) — the dominant fire ant across Broward County
- Size: Workers range 1/8 to 1/4 inch; a single mound holds varying sizes
- Color: Reddish-brown head and body with a darker abdomen
- Mound: Fluffy dome of loose dirt, no visible entry hole on top, often in sunny open lawn
- Sting: Burns immediately, then forms a white pus-filled pustule within 24 hours
- Why Florida: Our sandy soil, year-round warmth and no winter freeze let colonies stay active 12 months a year
Why Fire Ants Thrive in Broward County Yards
Red imported fire ants arrived in the United States through the port of Mobile in the 1930s and pushed south fast. South Florida turned out to be ideal habitat. There’s no hard freeze to knock back colonies, the soil is sandy and easy to tunnel, and our long rainy season keeps the ground soft enough for mounds to expand quickly. In Plantation, Sunrise and Davie, you’ll see mounds pop up almost overnight in the open, sunny parts of a lawn — exactly where kids and pets play.
Unlike the native ants most Floridians grew up with, fire ants are extremely territorial. Disturb the mound — even a careless lawnmower pass — and hundreds of workers boil out in seconds, ready to defend the colony. That speed and coordination is what makes them so much riskier than the ghost ants or sugar ants you find indoors.
What Makes a Fire Ant Sting So Dangerous
A fire ant doesn’t just bite. It grips your skin with its jaws to anchor itself, then pivots and drives in a stinger loaded with venom — often several times in a tight circle. That venom contains alkaloids that cause the signature burning pain and the raised white pustule that follows.
For most people
You’ll feel an instant burn, followed by itchy welts and pustules that can last a week or more. Scratching them open invites secondary infection, which matters a lot in our humid climate where wounds are slow to dry and heal.
For sensitive individuals
Roughly 1 to 2 percent of people develop a severe allergic reaction. Anaphylaxis — swelling of the throat, difficulty breathing, dizziness, a drop in blood pressure — is a medical emergency. South Florida’s fire ant density means stings here are common, and people who’ve never reacted before can become sensitized over repeated exposures.
Local warning: Fire ants are a serious risk to infants, elderly residents and outdoor pets in Broward County. A toddler who sits on a mound or a dog that digs into one can receive dozens of stings in under a minute. If anyone shows trouble breathing, facial swelling or widespread hives after stings, call 911 immediately.
The Hidden Dangers Beyond the Sting
Fire ants cause problems most homeowners never connect to them. They’re drawn to electrical fields and routinely chew into AC condensers, irrigation timers, pool pump controls and landscape lighting — common service calls across Plantation. Their mounds also damage lawns and can undermine pavers and walkways. And because a mature colony can field a quarter-million workers, a single property can host dozens of mounds before anyone notices the pattern.
How to Get Rid of Fire Ants — and Keep Them Out
Knocking the top off a mound feels satisfying but does almost nothing; the queen sits deep underground and the colony simply rebuilds. Effective control means reaching the queen. Here’s what actually works in South Florida conditions:
- Never kick or flood the mound. Disturbing it scatters the colony into satellite mounds and gets you stung. It also rarely reaches the queen.
- Use a two-step approach. Broadcast a slow-acting bait across the yard so foragers carry it back to the queen, then treat individual mounds directly. The bait does the deep work; the mound treatment handles the survivors.
- Time it right. Bait when ants are actively foraging — warm mornings and evenings in our spring and fall. Avoid the hottest midday hours when foraging drops off.
- Keep the yard less inviting. Trim back overgrowth, fix leaking irrigation, and remove standing food sources. Sunny, moist, undisturbed turf is fire ant paradise.
- Stay consistent. Reinfestation from neighboring properties is constant in dense Broward neighborhoods, so a single treatment is rarely the end of it.
Honestly, fire ants are one of the few pests where store-bought products often make things worse — flooding and partial kills push colonies to split and multiply. That’s why most homeowners in our service area hand fire ants to our ant control service in Plantation, where the yard is treated as a whole system rather than one mound at a time.
Protecting Kids, Pets and Outdoor Spaces
In a region where families spend most of the year outdoors, fire ants are a special concern around the spots people gather. Pay close attention to play sets, sandboxes, the edges of patios and pool decks, and the sunny stretch of lawn where kids run barefoot — these are exactly the warm, open areas fire ants colonize. Walk the yard before letting children or pets out, especially after the rainy-season storms that push fresh mounds up overnight.
Dogs and cats are frequent victims because they investigate or dig into mounds nose-first. A pet stung dozens of times can develop swelling, hives or, in severe cases, a dangerous allergic reaction, so keep an eye on any animal that suddenly yelps and starts pawing at its face or paws in the yard. Teaching kids to recognize and avoid the loose dirt domes goes a long way too. The goal isn’t to keep everyone indoors — it’s to clear the colonies so your South Florida yard is actually usable again.

Are fire ants active year-round in South Florida?
Yes. Because Broward County never gets a hard winter freeze, fire ant colonies stay active all 12 months. They slow slightly during cold snaps and the driest weeks, but they never truly go dormant the way they do in northern states, so treatment can be needed any time of year.
How do I tell a fire ant mound from a regular anthill?
Fire ant mounds are fluffy domes of loose, churned soil with no single hole on top — the ants enter through underground tunnels. They favor open, sunny lawn areas. If you disturb one and ants pour out aggressively within seconds, it’s almost certainly fire ants.
What should I do right after a fire ant sting?
Wash the area with soap and water, apply a cold compress, and avoid scratching the pustules so they don’t get infected in our humid climate. Antihistamines and hydrocortisone help with itching. Seek emergency care immediately if you notice throat swelling, trouble breathing or widespread hives.
Can I get rid of fire ants myself?
You can knock down individual mounds, but DIY efforts often cause colonies to split into multiple new mounds, making the problem worse. Reaching the queen requires the right bait, timing and yard-wide strategy, which is why professional treatment gives far more reliable, lasting results.
