A quarantine was introduced in the Sydney suburb of Enfield due to dangerous ants

In the Sydney suburb of Enfield, a strict biosecurity regime has been introduced following the detection of red imported fire ants at a local freight hub in late September. The restrictions cover an area within a two-kilometre radius of the logistics center, where the pests likely arrived from abroad inside a shipping container. According to experts from the Invasive Species Council, the spread of this pest could cost the Australian economy up to $2 billion annually.

As New South Wales Agriculture Minister Tara Moriarty noted, although the 60 specialists and nine scent-detection dogs deployed have not found any new specimens since the initial discovery, authorities decided not to take any risks. The daily life of most local residents will not change: the restrictions apply exclusively to the transportation of potentially hazardous materials capable of carrying insects. This list includes turf, soil, mulch, potted plants, and heavy machinery. Before moving such loads through the quarantine zone, businesses are required to subject them to special treatment.

Fire ants have a body length of 2 to 6 millimetres and a dark reddish-brown color. Most often, people notice not the insects themselves, but their nests, which look like patches of bare, loose soil or mounds up to 40 cm high without visible entrance holes. Entomologists confirmed that the Sydney find is not connected to the outbreak in south-east Queensland. The month-long gap between the detection of the pests and the imposition of the lockdown allowed the government to conduct an information campaign, including the opening of an advisory centre in Strathfield Park, where local residents are shown live insects in a secured container.
