How to report invasive ants in Australia

cnt-big-headed-ant

Yellow crazy ants and red imported fire ants are just two types of dangerous new invasive ants now found in Australia.

Unlike our native ants they are not a natural part of the Australian landscape, and can threaten our wildlife, ecosystems, agriculture and even people through their aggressive behaviour.

Most new infestations of invasive ants in Australia have been uncovered by ordinary people who saw something and reported it.

Uncovering new infestations before they spread is vital to keeping Australia safe from these dangerous ant species, and dramatically minimises the cost of eradication programs.

Due to their small size these ants can be hard to identify. We have compiled these identification resources to help you.

If you think you have seen any of these high risk ants, or if you are in doubt, please report what you have found to the biosecurity contacts for your state or territory listed below.
