Fire ants (Solenopsis invicta) are aggressive pests that pose a serious threat to Australia. They can have devastating impacts on our health, environment, economy, and outdoor way of life.
These ants swarm in large groups and deliver painful stings when their nests are disturbed. Their stings can cause severe or even fatal allergic reactions, such as anaphylaxis, in humans and animals.
The National Fire Ant Eradication Program (NFAEP) is working to detect, contain, and eradicate fire ants in South East Queensland, with the goal of eradicating them from Australia by 2032.
Why fires ants matter locally
Although the Widebay Region is outside the fire ant biosecurity zones, fire ants remain one of Australia’s most invasive pests. They can spread undetected through human-assisted movement of vehicles, equipment, machinery, and materials that can carry fire ants.
Occasionally, fire ants are detected outside the NFAEP’s containment boundary. These outlier detections are treated as a priority to prevent further spread.
Identify fire ants
Fire ants vary in size from 2 to 6 mm within a single nest and are copper-brown with darker abdomens.
Nests appear as mounds or flat patches of loose soil with no clear entry or exit holes. They can be found:
- in warm, open areas such as lawns, garden beds, and along footpaths or driveways
- under objects such as timber, logs, rocks, pavers, and bricks
- near utility pits and infrastructure such as water meters, gas meters, and power poles.
On rural properties, nests can be found near dams, farm edges, irrigation lines, fence lines, crops, and piles of organic matter.
Report fire ants
If you find suspect fire ants or nests:
- report online
- call 13 22 68 (132 ANT)
Please report sightings within 24 hours.
Help stop the spread of fire ants
There are simple actions you can take to help protect Queensland from fire ants:
Follow biosecurity requirements
In Queensland, the Biosecurity Act 2014 sets the rules for managing biosecurity risks. Everyone has a role in protecting Queensland from these risks. The rules include:
- Biosecurity Regulation 2016
- the general biosecurity obligation (GBO).
Under the GBO, you must take reasonable steps to prevent or reduce biosecurity risks in your activities.

Know high-risk equipment and materials
Certain equipment and materials can carry fire ants and spread infestations. You must check and manage these items carefully, especially if they come from a fire ant biosecurity zone.
High-risk equipment and materials include:
- soil
- hay and straw
- mulch or compost
- manure
- mining quarry materials
- turf
- potted plants
- soil attached to vehicles, machinery, and equipment
- non-traditional carriers such as pallets, shipping containers, portable buildings, and building materials stored on the ground.
Check your supplier
Before accepting equipment or materials, ask your supplier:
- Could it carry fire ants?
- Is it coming from within a fire ant biosecurity zone?
- How does your supplier comply with fire ant biosecurity requirements?
- Has your supplier followed fire ant-safe practices during purchase and delivery?
