Fire ant stings and your health 

Fire ants can swarm and sting many times. Stings cause a painful burning feeling, redness and itching. Small blisters may form within 48 hours. 

If you are stung, wash the area gently with soap and cool water. Apply a cold pack to help with pain and swelling. Do not scratch or break any blisters. 

Call 000 straight away if someone has trouble breathing, swelling of the face or throat, widespread hives, chest pain, nausea, heavy sweating or feels faint. Seek medical advice if symptoms worry you or if you are prone to severe allergic reactions. 

See advice for Health Practitioners. 

Keep pets safe 

Pets that spend time outdoors are at risk, especially animals that dig. Fire ants often swarm around the nose, mouth and ears. Stings can cause serious swelling and may stop an animal from eating, drinking or breathing. 

Keep pets away from suspected nests. If your pet is stung, move it away safely and contact a veterinarian promptly. Get urgent veterinary help if your pet has facial swelling or trouble breathing. 

About fire ants

Red imported fire ants are one of the world’s worst invasive species. They are dark reddish-brown with a darker brown-black abdomen. Nests can appear as flattish patches to mounds of soil up to 40cm high, with no obvious/visible entry or exit hole. 

These ants can have significant impacts on our health, lifestyle, environment, industries, and economy. 

Fire ants are aggressive and swarm in large numbers with a burning sting that can lead to anaphylactic allergic reactions.
