A “wildly toxic” chemical used to combat fire ants and the varroa mite in Australia is banned in Europe and harmful to humans – and it is poisoning waterways and killing native fauna, experts warn.

Fipronil acts as an insect nerve agent and is banned for use on crops in the EU, China, Vietnam and California because of its effect on pollinators. The insecticide was used in sugar baits across New South Wales in the now abandoned fight against the invasive varroa mite and has been injected into 35,539 fire ant nests in south-east Queensland and northern NSW since January 2023 as part of the national red imported fire ant eradication program.
