Fire ants are one of the world’s worst invasive species, with the ability to severely impact our environment, economy, agricultural industries, health, and our Australian way of life.
The presence of fire ants in NSW is notifiable under the NSW Biosecurity Act 2015. Medical practitioners have a duty to notify the NSW Department of Primary Industries and Regional Development (DPIRD) if they suspect or confirm a patient has been stung by fire ants in NSW.
Fire ants have been detected in NSW and are under eradication in Southeast Queensland by the National Fire Ant Eradication Program.
Medical diagnosis helps inform early detection
- If you suspect a fire ant attack has occurred in NSW, you must immediately report the case by calling the NSW Biosecurity Helpline 1800 680 244.
- Fire ant stinging attacks are most likely to occur in northern NSW, close to the QLD border, but could occur elsewhere in NSW.
- If ants are present on a victim, collect a specimen for identification.
- Wear latex gloves to prevent stings. Using a tissue, collect the ants and put them in a jar which can be sealed and place in the freezer.
Systematic allergic reactions
- Severe allergic reactions and anaphylaxis can occur following fire ant stings.
- Severe reactions and anaphylaxis may be more common in people previously stung by fire ants or who have a history of allergic reactions to insects.
Treatment of fire ant stings
- Use simple analgesia and a cold compress or ice to relieve swelling and pain
- Wash the affected area with soap and cool water and advise patients to keep the sting site clean
- Keep the blisters intact to prevent infection. Advise patients to avoid scratching
- Antihistamines can be considered to manage minor localised reactions and itching
- Topical or oral steroids can be considered for large, localised reactions
- Manage anaphylaxis immediately with adrenaline, as per standard anaphylaxis protocols
- Call 000 and refer to an Emergency Department if severe symptoms appear
- Call the Poisons Information Centre 131 126 for clinical advice
