Fire Ants in Brisbane and the Gold Coast: What You Need to Know
Fire ants are a significant invasive pest in Australia, first detected in Brisbane in 2001. They have since become a major concern for residents in Brisbane and the Gold Coast due to their aggressive behaviour, painful stings, and potential to harm local ecosystems and agriculture.
This article explains how to identify fire ants, understand their impact, and know the next steps if you suspect an infestation on your property.
What Are Fire Ants?
Fire ants are small, reddish-brown insects with darker abdomens. Measuring 2–6 mm in size, these ants vary in size within a single nest. Their colonies form dome-shaped mounds or appear as disturbed soil without visible entry or exit holes, as fire ants use underground tunnels to move in and out.
These ants are known for their painful stings, which can cause allergic reactions in some individuals. Beyond human discomfort, fire ants threaten native wildlife, crops, and livestock, making their eradication a national priority.
Identifying Fire Ants
Fire ants are small, reddish-brown insects with these distinct features:
- Size: Varies between 2–6 mm within the same colony.
- Colour: Copper-brown with a darker abdomen.
- Nest Appearance: Their nests often look like dome-shaped mounds or disturbed soil without visible entry or exit holes, as they use underground tunnels.

Why Fire Ants Are a Concern
Fire ants are not just a nuisance; they are dangerous. Their stings can cause severe allergic reactions in humans and animals. Additionally, they impact agriculture by harming crops, livestock, and native wildlife.
Where Are Fire Ants Found?
In South East Queensland, fire ants are commonly found in:
- Open areas like lawns, pastures, and roadsides
- Near or under objects such as timber, rocks, or garden pavers
- Around dams, irrigation lines, and fence lines in rural areas
Fire ant mounds may also form next to buildings or within landscaped areas, posing risks to homeowners and pets.
