Failing to stop the spread of an outbreak of invasive fire ants in south-east Queensland could cost the Australian economy more than $1bn a year, including damage to high-value crops, infrastructure and homes.
A previously unreleased cost-benefit analysis, commissioned by a steering committee managing the outbreak of red fire ants and obtained by Guardian Australia, says eradication of the species provides “much higher returns” than suppression measures that simply limit its spread.
