Broward County's dense St. Augustine lawns, automatic irrigation, and year-round South Florida warmth make fire ants a serious year-round problem for families and pets. Fire ant control is included in every Tier 1 pest control plan at no extra charge — no add-on, no separate service call. We use the research-backed Two-Step Method to eliminate colonies yard-wide, not just the mounds you can see.
The red imported fire ant (Solenopsis invicta) was accidentally introduced to the US from South America in the 1930s and has since become one of the most invasive and economically damaging pests in the southeastern United States. Broward County — flagged as a severe fire ant zone by the Florida Department of Agriculture and pest control operators across South Florida — sits at the intersection of every environmental condition that makes fire ant infestations severe, persistent, and difficult to control without professional treatment. Here's why.
Fire ants are more than a nuisance. Their aggressive swarming behavior and venomous sting create genuine health risks — especially for the children, pets, and families that fill Broward County's residential neighborhoods year-round.
Most fire ant stings cause localized pain and pustule formation. These symptoms below indicate a severe allergic reaction (anaphylaxis) — a life-threatening emergency requiring immediate medical attention.
Don't wait to eliminate fire ants from your Fort Lauderdale lawn. The safest approach is prevention — removing colonies before a sting event occurs. If you or someone in your household has a known insect allergy, treating fire ant infestations immediately is a health priority, not just a lawn maintenance decision. See our Fort Lauderdale pest control service for complete coverage details.
Fire ant mounds in Fort Lauderdale and Broward County lawns have distinctive characteristics that set them apart from other ant species. Here's what to look for — and what it tells you about the colony beneath.
Fire ant mounds are distinctive dome shapes — typically 6 to 18 inches across and several inches tall in mature colonies. Unlike most ant species, fire ants do NOT have a visible entry hole at the top of the mound. Entry and exit is through underground tunnels that may emerge several feet away from the visible dome.
Mature mounds can reach 18 inches in diameter and 12 to 18 inches in height in undisturbed areas. The soil in and around the mound appears loose and granular compared to surrounding compacted turf. After heavy South Florida rains or hurricane-related flooding, mounds are often freshly excavated and appear enlarged as ants rebuild flooded tunnels.
Fire ants prefer open, sunny areas for their mounds — St. Augustine grass lawns, along driveways and sidewalks, near AC units, in potted plant bases, and along fence lines. In Fort Lauderdale, the irrigated St. Augustine lawns common in Plantation, Coral Springs, Davie, and Weston are prime real estate for fire ant colonies.
The most unmistakable sign of a fire ant mound: any disturbance — from stepping, mowing, or even a vibration — triggers an immediate eruption of hundreds of aggressive worker ants that swarm upward within seconds. This defensive behavior is unique to fire ants and far more intense than any other Florida ant species.
Fort Lauderdale homeowners frequently call after heavy rains saying mounds appeared overnight. Rain floods the underground tunnel network and forces ants upward, creating new mound openings at higher elevations. South Florida's intense storm season — and the particularly heavy rainfall associated with tropical systems — makes this a recurring seasonal pattern in Broward County. Post-storm is when the true extent of an infestation becomes visible.
Fire ants are attracted to electrical fields and warmth. In Fort Lauderdale properties — where AC systems run near-continuously and irrigation control boxes are standard in nearly every yard — it's common to find colonies establishing beneath or inside HVAC condenser units and irrigation controllers. These hidden infestations cause equipment failures and significant repair costs, and they're easily missed during a standard visual inspection.
The Texas A&M Imported Fire Ant Research and Management Project developed and recommends the Two-Step Method as the most effective approach to fire ant control — adopted by university extension programs across the southern United States and the standard of care for professional treatment in South Florida.
Worker ants are foragers — they travel up to 100 feet from their mound to gather food. We broadcast EPA-approved IGR-coated granular bait across your entire yard using a calibrated Solo professional spreader. Workers pick up the bait during normal foraging activity and carry it back to the colony, where it's distributed to the brood and shared with the queen. The IGR (insect growth regulator) component prevents the queen from producing viable eggs, collapsing the colony's ability to reproduce.
This step is critical because it catches every colony in your yard — including satellite mounds and hidden colonies that haven't broken the surface yet. In Broward County's dense suburban neighborhoods, where colonies migrate freely from neighboring properties, yard-wide broadcast is the only approach that provides durable coverage.
For visible, active mounds — especially those near play equipment, walkways, pet runs, or adjacent to your home's foundation — we apply a professional liquid drench directly to the mound using a B&G stainless-steel sprayer. The liquid product penetrates deeply into the tunnel network to reach and kill the colony quickly, typically within 24 to 72 hours for the treated mound. This provides fast relief in the areas where fire ants pose the most immediate risk while the broadcast bait works across the rest of the yard over 1 to 4 weeks.
Contact sprays kill surface workers but the queen is underground, often several feet deep. She'll rebuild the colony within weeks. Boiling water kills only ~60% of colonies and kills the grass around the mound. Store-bought granules applied only to visible mounds miss satellite mounds entirely.
According to the Texas A&M fire ant research program, the Two-Step Method is the only approach proven to consistently achieve >90% control of fire ant colonies across a treated area. The combination of yard-wide bait coverage and targeted mound treatment for visible problem areas is what makes the difference between temporary relief and sustained control. Also see our Tampa fire ant control page for more information on this methodology.
Fire ant control isn't a separate appointment. Here's exactly what your Tier 1 technician does for fire ants as part of every scheduled general pest control visit — included in your plan, no extra charge, across all of Broward County.
Every Tier 1 technician walks the full property during each scheduled service visit — not just the interior and perimeter. They count visible mounds, assess fire ant activity level, and flag hot zones: children's play areas, pet runs, walkways, AC condenser units, garden beds, irrigation control boxes, and the foundation perimeter. In Fort Lauderdale's irrigated suburban properties, they pay particular attention to areas where automatic irrigation creates consistently moist soil — the highest-risk zones for new mound establishment. If fire ant activity has increased since the last visit, they adjust treatment on the spot. Covered by your plan, no separate scheduling.
When fire ant activity warrants it, your technician broadcasts EPA-approved IGR-coated granular bait across the entire lawn using a calibrated Solo handheld spreader. Worker ants forage up to 100 feet from their mound, so yard-wide broadcast ensures every colony has access to the bait — including hidden underground mounds you haven't spotted yet. Workers carry the bait back and share it with the queen, collapsing colonies from the inside out over 1 to 4 weeks. This step is performed as part of your regular Fort Lauderdale pest control visit, covered by your plan.
Active mounds in high-risk locations — near play equipment, along walkways, adjacent to the foundation, or in pet runs — receive a direct liquid drench using professional B&G equipment. The liquid penetrates the tunnel network for fast knockdown within 24 to 72 hours, addressing the immediate safety risk while the broadcast bait works across the rest of the yard. Your technician applies this each visit as warranted — it's part of your pest control plan, not an upcharge.
Every Tier 1 pest control visit includes a residual perimeter treatment around the home's exterior foundation — this is standard, not a fire-ant-specific step. Fire ants routinely move indoors through foundation cracks, utility penetrations, and expansion joints, especially during South Florida's hottest months and post-storm displacement events. The perimeter treatment kills workers attempting to enter the structure and discourages new colony establishment directly adjacent to your home. Covered by your plan, every visit.
After treating, your technician records fire ant activity levels, mound locations, and treatment observations for your property. These notes are referenced at the next visit so your service builds on itself — your technician knows which mounds collapsed, where new activity has appeared, and whether to prioritize bait broadcast or mound drench at the next service. Each visit is informed by the last, which is why consistent plan coverage is more effective than one-time treatments.
South Florida's year-round fire ant pressure means new mounds can appear between your scheduled pest control visits — especially after heavy rains and during peak hurricane season. If that happens, call us. As a Tier 1 pest control plan customer, we return and treat at no additional charge. No service call fee, no negotiation. Fire ant re-treatments between visits are covered the same way any pest callback is covered — it's part of what your plan includes.
We know that concerns about chemical treatments are real — especially when children and pets use the same lawn we're treating. Fort Lauderdale and Broward County's family-dense neighborhoods mean this concern is practically universal. That's why we're explicit about what we use, how we apply it, and what it means for your family.
The bait and drench products in our Two-Step protocol are EPA-approved formulations applied at label rates. Every product we use has been registered for residential lawn use by the EPA — meaning they've been reviewed for safety to people, pets, and the environment when used as directed. We apply them as directed.
