Naples golf course communities, manicured St. Augustine lawns, and automatic irrigation systems create the perfect fire ant environment — and Collier County ranks among the worst fire ant counties in Florida. The good news: fire ant control is included in every Tier 1 pest control plan at no extra charge. We use the research-backed Two-Step Method to eliminate colonies yard-wide, not just the mounds you can see. Safe for pets, kids, and barefoot living on the lanai.
The red imported fire ant (Solenopsis invicta) was accidentally introduced to Alabama from South America in the 1930s and has since spread throughout Florida. Collier County — and the Naples area specifically — represents one of the most concentrated fire ant environments in the state. The lifestyle that makes Naples desirable also makes it a fire ant paradise: golf course communities, automatic irrigation, manicured St. Augustine grass, sandy soil, and year-round outdoor living all contribute to an environment where fire ants thrive without interruption.
Fire ants are more than a nuisance. Their aggressive swarming behavior and venomous sting create genuine health risks — especially for children, pets, and anyone with insect allergies. Naples' year-round outdoor lifestyle amplifies this risk every single month.
Most fire ant stings cause localized pain and pustule formation. These symptoms indicate a severe allergic reaction (anaphylaxis) — a life-threatening emergency requiring immediate medical attention.
Don't wait to eliminate fire ants from your Naples 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.

Fire ant mounds in Naples 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. Pay special attention to paver decks, irrigation boxes, and lanai edges where Naples-area infestations commonly hide.
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 — often under pavers or through cracks in the lanai edge.
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 Naples summer rainstorms or irrigation, mounds are often freshly excavated and appear enlarged as ants rebuild flooded tunnels — this is when many homeowners notice them for the first time.
Fire ants prefer open, sunny areas for their mounds — St. Augustine lawns, golf course fairway edges, garden beds, along driveways and sidewalks, near AC units, in potted plant bases, and along fence lines. In Naples gated communities, the combination of open turf, manicured landscaping, and automatic irrigation creates prime fire ant territory across the entire lot.
The most unmistakable sign of a fire ant mound: any disturbance — stepping, mowing, or even vibration from a lawn mower nearby — triggers an immediate eruption of hundreds of aggressive worker ants within seconds. This defensive behavior is unique to fire ants and far more intense than any other Florida ant species. Children and pets are most at risk around active mounds.
Naples homeowners frequently call us right after summer storms — or even after heavy irrigation cycles — saying "mounds appeared overnight." Rain and irrigation saturate the underground tunnel network, forcing ants to move upward and create new mound openings. Post-rain is the best time to assess the true extent of a fire ant infestation on your property. What appeared to be one or two mounds often turns out to be a yard-wide infestation.
Fire ants are attracted to electrical fields, warmth, and sheltered cavities. In Naples properties, it's extremely common to find colonies establishing beneath paver pool decks, inside irrigation controller boxes, under lanai screening foundations, and around HVAC condenser units. These hidden infestations are easily missed during a casual visual inspection but pose significant risk to anyone using the pool or lanai area.
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. It's the method we use on every Naples property, included in every pest control plan at no extra charge.
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 Naples lawn 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 beneath pavers and irrigation boxes that haven't broken the surface yet. Broadcast bait is how we achieve yard-wide coverage across even the largest Naples estate lots.
For visible, active mounds — especially those near pool decks, play equipment, screened lanai entrances, 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 damages the surrounding St. Augustine grass. Store-bought granules applied only to visible mounds miss satellite mounds entirely — and in Naples with its constant irrigation, those satellite mounds grow rapidly.
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 main fire ant control page for additional background on this method.
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 Naples pest control visit — included in your plan, no extra charge.
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, pool deck pavers, lanai edges, screened enclosure foundations, irrigation control boxes, AC condenser units, and garden beds. If fire ant activity has increased since the last visit, they adjust treatment on the spot. This complete property walk is part of your Naples pest control plan — no separate scheduling, no extra cost.
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 beneath your Naples pool deck or irrigation risers. 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 pest control visit, covered by your plan at no extra charge.
Active mounds in high-risk locations — near pool decks, lanai access points, 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 Naples' hottest months. The perimeter treatment kills workers attempting to enter the structure and discourages new colony establishment directly adjacent to your home or lanai enclosure. Covered by your plan, every visit.
After treating, your technician records fire ant activity levels, mound locations, and treatment observations for your Naples 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. For properties in gated communities with HOA landscaping crews, we also note where neighboring common areas show activity that may be migrating into your lot.
Naples' year-round fire ant pressure means new mounds can appear between your scheduled pest control visits — especially after heavy summer rains or periods of increased irrigation. If that happens, call us. As a Tier 1 Naples 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 play barefoot on Naples lawns and pets roam pool decks and lanai areas year-round. 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.
