    Funny you should ask that. I think they're different, the Bromadiolone seems to be faster acting.

    I just read this:

    Long-acting anticoagulants (LAACs) are the most common and well known type of mouse and rat poisons. This type of poison prevents the blood from clotting, resulting in internal bleeding. Long-acting anticoagulants work similarly to the “blood thinner” medications that people take (e.g., warfarin or Coumadin®). When dogs or cats ingest LAACs, it typically takes 3-5 days before signs of poisoning are visible. However, if the pet has been chronically exposed to the product, the onset of clinical signs may be sooner. Common signs of poisoning include signs of internal bleeding: lethargy, exercise intolerance, coughing, difficulty breathing (due to bleeding into the lungs), weakness, and pale gums. Less common signs include vomiting, diarrhea (with or without blood), nose bleeds, bruising, bloody urine, swollen joints, inappetence, and bleeding from the gums.


    Fortunately, this specific type of mouse and rat poison does have a prescription antidote called Vitamin K1. Over-the-counter medications or food with high vitamin K content will not be sufficient substitutes. Most pets need to be treated with Vitamin K1 for 30 days. Two days after the last dose of Vitamin K1 is administered, a blood clotting test called a prothrombin (PT) should be checked to make sure the clotting is normal; otherwise, your pet can still potentially bleed out despite one month of therapy!


    The dose needed to cause poisoning from LAACs varies greatly between active ingredients and species of animal. With some types (e.g., brodifacoum), it only takes a very small amount to cause poisoning, especially in dogs. Other types have a wider margin of safety (e.g., bromadiolone) and it takes a larger amount to cause poisoning. In general, cats are typically quite resistant to the effects of LAACs and often require a much higher dose than dogs to cause poisoning. The age and health of the pet may be another factor determining whether or not the amount ingested will be poisonous. Animals with underlying liver or gastrointestinal disease, as well as the very young or very old, are more at risk.

    If you value native birds of prey don't use it.

    It's an economic issue in the longer term, but very much an environmental one now.

    Perhaps there's a case for feral cats after all...

    Having seen some feral cats, they would take down all but the largest Birds of prey.

    The AVPMA blocked the use of brodione in NSW. They are the non-political body overseeing the use of pesticides and herbicides in Oz.
    Of course they are a political body - in fact they are a Federal Statutory Authority coming under the Agriculture Department. Now they normally operate independently but can be over ridden by the relevant Federal Minister if required - they were the agency that Barnaby moved to his electorate a few years back - you can look it up as the reason was political and we cannot talk politics here.

    They're not a problem where I lay the baits, none of it is outside and it is hopefully where other animals cant get to it... except my dog is a ninja. I now generally use cage traps and buckets.

    Sure. Some of the cats I've seen could possibly take down a feral goat. It's about percentages I guess.

    The feral animal population is now done and dusted. Nothing we can do to put it back as it was, and therefore get over it and move on. Us whitefellas are the most feral of them all.

    Here is the story of the independent authority the APVMA [ Australian Pesticides and Veterinary Medicines Authority ] rejecting the NSW government application. And the reason scientists are worried about the use of Bromadiolone.


    Bromadiolone poison to control mouse plague rejected for use by APVMA - ABC News





    NSW mouse plague to be fought with ‘napalm’ like bromadiolone. So, what is it and should you be worried? - ABC News
    I’m pretty sure the dinosaurs died out when they stopped gathering food and started having meetings to discuss gathering food

    A bookshop is one of the only pieces of evidence we have that people are still thinking

    We don't use baits, for animal safety reasons. We have a lot of carnivorous birds, such as maggies, kookies, butchies, Pacific bazas, owls, nightjars, several hawks/harriers and a family of wedgies., not to mention our resident snakes.

    Another reason is that we have a good population of antechinus and a few phascogales, whose diets quite often include rodents.
