Fire Ant Program: Chemical Sparks Concern

After raising concerns about the use of Pyriproxyfen in the fire ant prevention program, I was told by CEO Scott Hansen (APVMA) that it should not be used as a preventative measure—even after I pointed out that this is exactly what’s happening in South-East Queensland under the Queensland Fire Ant Eradication Program. I also presented evidence of widespread breaches of the permits governing the use of these chemical poisons.

In addition, I raised concerns about confusion in the permits regarding the use of chemicals near and in waterways, particularly given that S-Methoprene is highly toxic in marine environments.

Mr Hansen made it clear that treatment responsibilities fall under state jurisdiction and that the Commonwealth does not exercise oversight over how these chemicals were used. While there is a Commonwealth–State partnership, he explained that governments rely on international safety data rather than local studies. He confirmed that permit requirements are currently under review.

Mr Hansen also advised that complaints can be submitted through the Adverse Experience Reporting Program, and noted that there are currently 28 reports under consideration relating to fire ant concerns.
