Fire Ant

December 8, 2014

Family Structure

  • Form colonies which are ruled by small groups of queens or single queens
  • Even if only one queen survives, a colony can expand to thousands within a month or so
  • There may be multiple queens in some colonies


  • Large mounds in open area
  • Mounds can reach heights of 40 cm (15.7 in)
  • Mounds can also be as deep as five feet
  • Nest in moist soil, near river banks and ponds, lawns and freeway medians
  • Nest not visible; built under landscaping timbers, rocks and similar objects
  • Dome-shaped mounds will be constructed if no cover; usually found in open spaces e.g. fields, parks and lawns


  • Young plants, seeds, and sometimes crickets
  • Often attack small animals; can even kill them
  • Bite only to get a grip; then sting (from the abdomen)
  • Inject a toxic alkaloid venom called solenopsin which produces a painful sting, similar to what one feels when burned by fire—hence the name “fire ant”
  • Venom can be deadly to some individuals
