Invasive insects

The tawny crazy ant has invaded North and South America. In areas colonised in Texas, this ant has within one year reached densities up to two orders of magnitude greater than the combined abundance of all other ants. Photo: Alex Wild and Ed Le Brun

Australia already has more than its fair share of harmful insects that are not native to the country but are causing massive harm to our native plants, animals and ecosystems.

Queensland is battling red fire ants through a 10 year, $411 million eradication plan. Yellow crazy ants threaten our Wet Tropics World Heritage Area, the oldest continuously surviving tropical rainforests on Earth and the most biologically diverse region in Australia.

Invasive insects attack and kill our native animals, out-compete our native insects, carry diseases and attack our Australian plant species.

We must do all we can to keep other invasive insects from entering Australia, and control and where possible eradicate those already here.

Invasive ants

People, wildlife, agriculture, infrastructure – no aspect of our lives is safe from the destructive power of invasive ants now found in Australia.
