Red Imported Fire Ants

Red imported fire ants (fire ants) are an invasive species which originated in South America. Fire ants are now present in South East Queensland and have the potential to seriously affect local biodiversity and outdoor lifestyles. Because they swarm and sting, fire ants pose a serious threat to people and domestic animals. Reporting and treating fire ants wherever they are found is essential to manage the impacts of this species.

The National Red Imported Fire Ant Eradication Program is a collaboration between the Australian Government and all state and territory governments and is leading the containment and eradication plan for fire ants. 

What do they look like?

Fire ants are small, with varied sizes ranging from 2-6mm. They are coppery brown in colour and have a darker abdomen. 

What do their nests look like?

Fire ant nests can be inconspicuous and look like a small bucket of soil that has been gently tipped onto the ground. There are no entry or exit holes on the nests, and no ant activity will be observed if the nest is undisturbed. Nests can be established in garden beds, lawns, pot plants, along fence lines, at the base of trees, and along the edge of concrete paths.

Staying safe

Despite being small, fire ants are an aggressive species. Fire ant stings are painful and can cause allergic reactions. If you suspect you have fire ants, keep children and pets away from the area where you think there is a nest, don’t touch the nest or break it open until treatment has been completed.

If you find fire ants on your property, these need to be reported to the program by phoning Biosecurity Queensland on 13 25 23, or via their online portal.
