The Fear of Fire Ants


Fire ants, native to South America, were discovered in Brisbane in February 2001. The National Fire Ant Eradication Program, led by Biosecurity Queensland, has been using the latest research and techniques to significantly reduce fire ant numbers since the program began in September 2001.

Fire ant facts

  • Fire ants inflict a painful sting, followed by itchy pustules, which can take months to heal
  • Destroy the environment
  • ŸImpact on agricultural production, mainly by destroying seeds
  • ŸThreaten our outdoor lifestyle and stop children from playing safely in backyards and parks
  • ŸHave caused many deaths and thousands of people to be hospitalised with allergic reactions in the USA

  • ŸSmall, ranging in size from 2 to 6mm

What should you do?

If you suspect you have fire ants

  • ŸAll Biosecurity Queensland on 13 25 23
  • ŸNever touch the ants or their nest
  • ŸNever try to treat or remove the nest yourself
  • ŸNever move high-risk, potentially infected items off your property

IMPORTANT: Never treat a suspected fire ant nest. Correct identification is essential, as ants or a nest may not be fire ants, and killing the wrong type of ants may be harmful to an ecosystem or environment.

If you bitten by fire ants

  • Apply a cold compress to relieve the swelling and pain
  • Gently wash the affected area with soap and water, and leave the blister intact
  • Then seek medical attention, ESPECIALLY IF YOU ARE ALLERGIC TO INSECT STINGS AND BITES!

How can you help?

  • Regularly check your property (including residential and business) and report any suspected ants or nests
  • ŸIf you live or work in a fire ant restricted, check with Biosecurity Queensland before moving high-risk items such as: soil, sand and similar products, mulch and compost, pot plants and potting mixes, baled hay and straw, landscaping and construction materials, earthmoving machinery and equipment, and material that has been in contact with the ground for an extended period of time
  • ŸBefore excavating your property, arrange for a free Biosecurity Queensland site inspection
  • ŸWhen purchasing high-risk items, ask your supplier or service provider if the product is fire ant free
  • ŸBecome a fire ant volunteer ranger and help minimise the treat of fire ants to your community
