Identifying it in North Carolina

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 honey bee sting, carpenter ant bite, bald-faced hornet sting — all of which are also recorded in North Carolina.

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

Season in North Carolina specifically

Records in North Carolina concentrate in March, April, May, October, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in North Carolina runs March to November.

Because open sunny ground — lawns, parks, roadsides and pasture across the Southeast and parts of the Southwest, exposure in North Carolina 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.

Care

  1. move away from the mound and brush ants off — do not stand still
  2. wash and apply a cold pack
  3. leave the pustule intact; breaking it invites infection
  4. antihistamine for itch
