Associate Professor John White @johnwhitewildlife.bsky.social · 24/10/2025Why we need better management of rodenticides post. A #rentokil bait station at the interface af a pond with wildlife and a public swimming pool. All rodenticides must be within 3m of a building. This is at least 20m from a building and in a place where it will attract the attention of wildlife. 031
Associate Professor John White @johnwhitewildlife.bsky.social · 23/10/2025It bothers me so much that every building I encounter has rodenticides outside them. The bait in these boxes out doors will more than likely spread to the food chain. We need to do so much better and ban second generation anticoagulant rodenticides (SGARs). Do better APVMA!! 3369

Associate Professor John White @johnwhitewildlife.bsky.social · 10/08/2025Could the APVMA be any more clear how they view scientific evidence of rodenticide poisoning of our wildlife? Time to ditch our regulator? #APVMA 061
Associate Professor John White @johnwhitewildlife.bsky.social · 28/07/2025So apparently the APVMA is supposed to release the recommendations of their review into rodenticides in Australia this month (only a few days left). It is over a year late and we still have no indication if they will do anything. Rat poison is a disaster for our wildlife. @davidpocock.bsky.social 193
Associate Professor John White @johnwhitewildlife.bsky.social · 28/07/2025When you reach for the rat poisons, stop for one second and think about where it goes. Often not rats and mice. Here we demonstrate it ends up in possums, many are then eaten by predators like powerful owls. Please avoid second generation anticoagulants 🙏♥️🦉 www.sciencedirect.com/science/arti... 34924
Associate Professor John White @johnwhitewildlife.bsky.social · 10/07/2025Fire not only resets our biological infrastructure but also has significant economic costs. Fire is good for ecosystems in the right dose, but the more frequent mega-fires we are seeing in the Grampians are not good. 080
