Yellow crazy ant infestation could spread to Queensland's wet tropics, conservationists warn

Calls for urgent funding from state and federal governments to deal with one of the world's worst invasive species

One of the world's worst invasive species could spread into Queensland's wet tropics world heritage area unless there is urgent intervention from the state and federal governments, conservationists have warned.

Yellow crazy ants, which spit formic acid and can form supercolonies that overwhelm native species, have long been an issue in the country's north, including in Cairns where they have encroached on the world heritage area.
