If you’ve ever stepped outside in Florida and encountered a sudden, burning sting, chances are you’ve crossed paths with fire ants.
As a second-generation owner of Hoffer Pest Solutions, I’ve seen firsthand the challenges these aggressive insects present to homeowners and businesses alike. In South Florida’s warm, humid climate, ants thrive year-round, making effective pest control essential to protecting homes, families, and pets.
Identifying Big Red Ants in Florida
Florida is home to several species of large red ants, each with unique behaviors and risks. Proper identification is the first step in effective control. Carpenter ants have larger bodies and prefer wood, while fire ants are smaller, aggressive, and build soil mounds.
Fire Ants (Solenopsis invicta)
Fire ants are the most notorious red ants in Florida. These invasive pests are highly aggressive and build large mounds in open, sunny areas. Their painful stings inject venom that causes burning sensations, pustules, and, in severe cases, allergic reactions.
Florida Carpenter Ants (Camponotus floridanus)
Often mistaken for fire ants, Florida carpenter ants have reddish-brown thoraxes and black abdomens. Unlike fire ants, they do not sting, but they can bite and spray formic acid as a defense mechanism. They prefer nesting in moist, decayed wood, which can lead to structural damage in homes.
Velvet Ants (Cow Killers)
Though often called "ants," velvet ants are actually wingless wasps. Their bright red and black coloring is a warning sign of their incredibly painful sting, ranking high on the Schmidt Pain Index. Fortunately, they are solitary and pose little risk unless provoked.
The Risks of Red Ant Infestations
Fire ants and velvet ants deliver painful, venomous stings, while carpenter ants can cause discomfort with their bites. They also build extensive colonies that disrupt soil and can damage grass and plant roots. Fire ant stings can lead to allergic reactions, requiring medical attention in some cases.
Carpenter ants tunnel through wood, potentially weakening the integrity of homes and decks.
DIY Solutions For Red Ant Removal
Boiling Water Method
Pouring boiling water on fire ant mounds can kill many ants, but it rarely eliminates the entire colony. This method works best when combined with other control strategies to ensure long-term effectiveness. Since fire ants have extensive underground tunnel systems, the boiling water may not reach the queen, leading to colony relocation.
Prevent Colony Relocation: Use long-lasting bait and treat the entire yard, not just visible mounds.
Homemade Borax Baits
Mixing borax with sugar can attract and poison worker ants, but effectiveness varies by species. Place small amounts near ant trails and refresh regularly for continuous control. Patience is key, as borax baits work gradually by disrupting the ants’ digestive systems.
Diatomaceous Earth
A pet-friendly, natural solution that dehydrates and kills ants when applied to nests and entry points. It must be kept dry to remain effective, so frequent reapplications may be necessary in Florida’s humid climate. Sprinkling a barrier of diatomaceous earth around entry points and foundations can help deter ants from entering your home.
Pet Safe Red Ant Control: Diatomaceous earth and bait stations placed out of pets’ reach. It is effective during the rain season, but needs to be reapplied after rain.
Store-Bought Solutions
Advion Fire Ant Bait: Highly recommended by professionals for its effectiveness and long-lasting results.
Granular Baits vs. Liquid Baits: Fire ants prefer granular baits over liquid, which are often ineffective against them.
