Fire ants in Florida
Yes — fire ants are recorded in Florida. The GBIF biodiversity database holds 6,765 verified fire ant records from the state — one of the highest counts in the country. Sightings concentrate in March to April. Onset: immediate burning. Duration: pustule 3 to 10 days, mark can persist for weeks.
| Verified records | 6,765 |
|---|---|
| Peak sightings | March to April |
| State bite season | January to December |
| Active | daytime, especially after rain when mounds are rebuilt |
| Habitat | open sunny ground — lawns, parks, roadsides and pasture across the Southeast and parts of the Southwest |
| Bite appears | immediate burning |
Fire ant bites in Florida: what the mark looks like
Fire ants sting rather than bite: they anchor with their jaws and sting repeatedly in an arc, which produces a curved group of welts rather than a single mark. The sterile pustule that appears the next day is close to unique among American stinging insects and is the most reliable identifier.
Locally, the species most often confused with it are black widow spider bite, bald-faced hornet sting, mosquito bite — all of which are also recorded in Florida.
Seek medical care if
Call emergency services now for difficulty breathing, swelling of the lips, tongue or throat, dizziness or fainting, or hives spreading away from the bite.
- difficulty breathing, throat tightness, dizziness or hives away from the sting site — call emergency services
- a previous severe reaction to any sting
- stings covering a large area, particularly in a small child
What else it could be in Florida
These are recorded in Florida too and are the ones most often confused with it here. The differences below are the ones that actually separate them.
| Fire ant sting | Flea bite | |
|---|---|---|
| Pattern | multiple stings in a ring or cluster — the ant grips and pivots | clusters of three or four, or short irregular groups |
| Where on body | feet, ankles, lower legs | ankles, shins, behind the knees |
| Appears | immediate burning | immediately to within an hour |
| Records here | 6,765 | 67 |
Fire ant season in Florida specifically
Records in Florida concentrate in March to April, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Florida runs January to December.
Because open sunny ground — lawns, parks, roadsides and pasture across the Southeast and parts of the Southwest, exposure in Florida tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.
Month by month in Florida
These are the 6,765 Florida records broken out by the month they were recorded — not a national curve redrawn for the state. Records appear in 12 of the 12 months here. The single busiest month is March with 1,906 records (28% of the state total).
| Month | Records | Share |
|---|---|---|
| January | 631 | 9% |
| February | 613 | 9% |
| March | 1,906 | 28% |
| April | 881 | 13% |
| May | 490 | 7% |
| June | 261 | 4% |
| July | 178 | 3% |
| August | 214 | 3% |
| September | 300 | 4% |
| October | 606 | 9% |
| November | 302 | 5% |
| December | 322 | 5% |
Counts are observations submitted to GBIF, not bites. They tell you when the animal is out and being noticed in Florida; they do not tell you how many people were bitten. The thinnest month with any record at all is July (178).
How Florida compares
Across the 24 states with any fire ant records, Florida ranks 2nd with 6,765. The state directly above it is Texas (11,815). Directly below is North Carolina (1,204). The highest count anywhere is Texas (11,815).
Inside Florida itself the picture is different again: of the 20 biting species we track with records here, this one is 2nd and accounts for 23% of the 30,054 records logged in the state. A species can be common nationally and marginal in one state, or the reverse — which is the whole reason this page exists separately from the national guide.
Care
- move away from the mound and brush ants off — do not stand still
- wash and apply a cold pack
- leave the pustule intact; breaking it invites infection
- antihistamine for itch
Avoiding fire ants in Florida
- look before standing or sitting on grass in fire ant country
- closed shoes outdoors
- treat mounds in the garden rather than kicking them
