Tell Wagga Wagga City Council to Stop Poisoning Wildlife.
Wagga Wagga City Council uses Muskil Dual Active — a single product containing both difenacoum and bromadiolone, two potent SGARs — for rodent control. These active ingredients accumulate in native predators through secondary poisoning, threatening the owls, raptors, and wildlife of the Murrumbidgee region. Send a direct email to the General Manager asking them to stop.
Two SGAR active ingredients in one product — used across NSW's largest inland city.
Secondary poisoning of native wildlife
SGARs accumulate in the tissue of poisoned rodents and remain lethal for days. Native predators — powerful owls, wedge-tailed eagles, raptors, quolls, and antechinus — are exposed when they eat affected animals. Research led by Prof. Raylene Cooke and Assoc. Prof. John White at Deakin University has documented SGAR toxins in the livers of native predators across Australia.
Active regulatory review by the APVMA
The Australian Pesticides and Veterinary Medicines Authority is currently reviewing SGAR registrations following evidence of widespread non-target harm. Councils continuing to use these products risk being on the wrong side of an emerging regulatory shift.
Effective alternatives already exist
Non-anticoagulant products such as Selontra (colecalciferol) provide effective rodent control with no secondary poisoning risk to native wildlife. Wagga Wagga City Council can specify SGAR-free products in its rodent management contracts — a straightforward update that requires no compromise to outcomes.
