Fire Ants Are Swarming Central Florida in 2024: Here’s How to Fight Back
Central Florida homeowners are facing an unprecedented challenge in 2024 as fire ant populations surge to alarming levels across the region. Climate change is bringing warmer, wetter weather that favors fire ants, while Florida’s urban sprawl also means more disturbed landscapes fire ants seek, with fewer natural predators, and more ants hitching rides in potted plants to new landscapes. This perfect storm of conditions has created an environment where these aggressive invaders are thriving like never before, making effective control strategies more crucial than ever for protecting your family and property.
Understanding the 2024 Fire Ant Population Explosion
The red imported fire ant (Solenopsis invicta), which was accidentally introduced to the U.S. from South America in the 1930s, has since spread throughout the southern states, especially Florida, where warm weather and moist soil allow them to thrive year-round. What makes 2024 particularly challenging is the combination of environmental factors that have accelerated their reproduction and spread.
During breeding season, winged male and female ants (called alates) swarm into the air to mate. After mating, queens establish new colonies, often just a few hundred feet from the parent mound. This reproductive cycle explains why fire ant populations spread so quickly throughout the state. The queen will lay up to 800 eggs per day, growing the colony to an average size of 100,000 to 500,000 ants.
The surge is particularly noticeable in Central Florida, where hybrid fire ants—crossbreeds between red and black fire ants—are found mainly in Central Florida. These colonies are not only numerous but incredibly resilient, with reinfestation by fire ants noticeable within a month after treatment, and if fire ant control is not maintained, the subsequent reinfestation of an area may result in even greater fire ant populations than existed before the application of insecticides.
The Hidden Dangers of Fire Ant Infestations
Fire ants pose serious threats that extend far beyond painful stings. Fire ants are notorious for their painful, burning stings that result in pustules and intense itching, which can persist for up to ten days. If the pustules are broken, infections may occur. Some people even have allergic reactions to fire ant stings. These small, yet powerful, insects bite and sting approximately 14 million people each year.
Beyond human health risks, red imported fire ants rank among the world’s most invasive and destructive species, causing $8.75 billion in yearly economic damages in the U.S. They chew on fruits, roots and stems, damaging crops, swarm and harm newborn calves, and their mounds damage mowers, balers, combines and other farm equipment. On the homefront, they nest in air conditioners, sprinkler controls, utility boxes and traffic signals, gnawing on insulation that triggers short circuits, power outages and expensive repairs.
Proven Control Strategies for 2024
The Two-Step Method: Professional Standard
Eliminating fire ants requires persistence and proper timing. The most effective methods combine baiting, mound treatment, and professional pest control when necessary. The most successful approach involves a systematic two-step process that targets both existing colonies and prevents future infestations.
Apply ant bait evenly over the lawn or yard, rather than directly on the mounds. Worker ants carry the bait back to the colony, feeding it to the queen. In Florida, spring and fall are the best times for bait applications because ants are most active and foraging for food. Baits contain active ingredients dissolved in a substance ants eat or drink, and to be effective, baits must be fresh and applied when ants are actively foraging.
Advanced Baiting Techniques
Using bait is one of the most effective methods for controlling fire ants. It targets both the workers and the queen, offering a comprehensive approach to reducing the population. For maximum effectiveness, apply baits when ants are actively foraging, usually in the late afternoon or early evening, and make sure the ground is dry as moisture can affect the bait’s effectiveness.
Products like Extinguish Fire Ant Bait and Amdro are highly effective. Some bait ingredients affect the nervous system, including abamectin, indoxacarb, metaflumizone, spinosad, and fipronil. Others affect the digestive system or metabolism, while some interfere with reproduction or growth.
Direct Mound Treatment Options
For visible mounds, apply insecticidal dusts or mound drenches directly over the nest. Treatments for fire ant control may be more effective on sunny, cool mornings when the majority of ants and brood are closer to the surface of the mound. Scalding water (190ºF-212ºF) has been used on mounds with an elimination success rate of 20%-60%. Slowly pour at least 3 gallons onto the mound, being careful to avoid getting burned.
Previous research suggests that the use of hot water, and especially the use of low-pressure hot water injection, is a method that can be used as a centerpiece for developing nontoxic IPM strategies for fire ants and other invasive ants or as a complement to toxic baiting strategies.
Natural and Organic Solutions
For homeowners preferring eco-friendly approaches, another fire ant treatment is a solution containing citrus oil. D-limonene, the natural component found in the oils of citrus peel, is toxic to fire ants and can be an effective ingredient to add to home remedies for active mounds. Commercially available organic products that contain ingredients such as boric acid or diatomaceous earth can kill ants, and some products have ingredients derived from botanical sources, such as rotenone, nicotine sulfate, d-limonene, and pyrethrins. Spinosad is considered organic because it comes from a bacterial fermentation process.
Professional Fire Ant Control: When to Call the Experts
While DIY methods can provide temporary relief, pest control service is the most effective method to control fire ant infestation, by providing regular inspections and treatments all year long. It is recommended that you seek professional pest control services to effectively eliminate fire ants from your property, as professional pest control technicians have the knowledge and tools needed to assess the extent of the infestation and apply appropriate treatments.

These locally owned and family-operated pest control businesses are here seven days a week and are locally owned and family-operated pest control businesses.
Integrated Pest Management (IPM) Approach
The goal of IPM strategies for fire ants is to prevent or eliminate problems caused by unacceptably high numbers of fire ants, rather than eliminating all ants from the ecosystem. Another option is to implement an integrated pest management program (IPM). IPM incorporates biological control methods and selective use of insecticides.
Scientists began releasing phorid flies from fire ants’ native South America in the 1990s as natural parasites of fire ants. The USDA has released six species of phorid fly to help control workers in multi-queen colonies, and all of the released species have been established.
Prevention: Your First Line of Defense
Effective fire ant control in 2024 requires proactive prevention strategies. Regularly inspect your yard and property for new fire ant mounds. Walk around your lawn, garden, and any other open areas, especially after rainfalls which often trigger mound building. Fire ants are most active during the warmer months but can remain active year-round in milder climates like West-Central Florida. Rainfall often triggers the building of new mounds as fire ants move to higher ground.
Maintain your landscape to discourage fire ant establishment. Keep your outdoor areas clean and free of food debris that may attract ants, and keep vegetation trimmed and away from structures to reduce potential nesting sites.
The Reality of Long-Term Control
It’s important to set realistic expectations about fire ant control. Unfortunately, no fire ant control method (with possibly the exception of biological control agents) will permanently eliminate ants from an area. Fire ants can quickly re-infest areas after treatment stops, and may even resurge with greater populations. Fire ants cannot be eliminated entirely because it is not possible to treat all infested areas. There may not be one best method for fire ant control, especially in large areas. Your objective should be to find the method or methods that are most cost-effective, environmentally sound, and fit your tolerance level for fire ants.
Maintaining long-term control over fire ants requires understanding their behavior, using effective baiting techniques, regularly monitoring them, and selecting the appropriate treatments. Fire ants can be persistent pests, but you can keep your property safer and comfortable year-round with a consistent strategy.
Take Action Against the 2024 Fire Ant Surge
The fire ant population explosion in Central Florida demands immediate and sustained action. Whether you choose DIY methods or professional intervention, the key is consistency and proper timing. Fire ant colonies can sometimes relocate or new colonies can form, making it necessary to reapply treatments every few months during active seasons for best results.
Don’t let fire ants take over your property in 2024. By implementing these proven control strategies and working with experienced local professionals who understand the unique challenges of Central Florida’s fire ant surge, you can protect your family, pets, and property from these aggressive invaders. Remember, the most effective approach combines multiple strategies tailored to your specific situation and maintained consistently throughout the year.
