The dangers of rat poisons
Second-generation anticoagulant rodenticides (SGARs) are potent rat poisons that pose significant risks to wildlife and companion animals. As concerns over their environmental impact grow, there's an urgent need to explore safer alternatives.
What are SGARs?
SGARs are a group of highly toxic poisons used to kill unwanted rodent populations. They are more potent and longer-lasting than their first-generation counterparts (FGARs), which have fallen out of favour due to safety and environmental concerns. SGARs work by interfering with the blood clotting mechanism, leading to internal bleeding and eventual death in their victims. However, non-target species, such as birds of prey and other wildlife, are also at risk if they consume toxic rodents or bait.
Wildlife under siege
SGARs are wreaking havoc on our native fauna, causing untold suffering and disrupting delicate ecosystems. The widespread use of these poisons threatens our biodiversity and demands urgent action.
-
Birds of prey are particularly vulnerable to SGARs. A staggering 92% of analysed birds had SGARs in their systems, leading to slow, painful deaths that can last for days.
-
Vulnerable species like quolls and possums face high risks of SGAR poisoning, either through direct bait consumption or by eating poisoned prey.
-
By decimating predator populations, SGARs inadvertently allow rodent numbers to surge, creating further ecological instability.

Recent Australian studies reveal lethal SGAR concentrations in 33% of powerful owls, 42% of southern boobooks, 68% of tawny frogmouths, and 80% of barn owls. These numbers underscore the urgent need for action.
