    I don't know if y'all have seen this but a new hog pesticide has been approved for use in Texas. It is Warfarin based. Warfarin is long acting anticoagulant that is transmissible through the food chain. It is used in some rodenticides, but now they want to use it for hogs with special feeders that are supposed to alleviate by-kill of non target species. Warfarin is a better choice than cyanide, but is hardly a good choice given the potential for cross-species poisonings, either through direct ingestion or by eating the carcasses of animals poisoned by it. It also will make feral hog consumption more dangerous. No doubt this will impact hog doggers and trappers as well who sell live hogs for consumption.

    Texas was also testing sodium nitrate (meat preservative) which is much less harmful to the environment and won't harm animals that feed on hogs that have ingested it, but this choice was apparently abandoned after the USDA approved warfarin for hog killing. Texas is subsequently giving up funding for research into hog control ($900K per year) as well because of the approval of warfarin use.

    To be used, it must be in specialty traps by licensed individuals who have had training in its use. Hogs must be first trained on how to use the traps before introducing the poison which will require multiple feedings to be lethal. Once lethal, the process must start again with new hogs, teaching them how to use the traps...

    There is a petition started to put a halt to the use of this product before it gets started.

    Warfarin has been around for over 70 years and used in humans daily.

    I haven't seen any valid argument against it, yet....

    Neighbor used it on ground squirrels at his ranch. Cost me a good dog when she ate the sick ones. Bad stuff.

    But the dosage is monitored and regulated by a doctor. If eating a hog that's been poisoned what dosage are you ingesting? Can easily be life threatening especially if your already on warfarin.

    Good old fashion hunting seems like a much better approach.

    Saw some rat bait once that was treated milo and other seeds. Of course your use is off label.

    Yep.


    Of cource the warfarin can simply be mixed with deer corn and put into deer proof hog feeders. The trick is getting it in big enough quantity to kill hogs.

    Another option is good old antifreeze and corn. Likewise, when put in deer proof feeders it kills hogs for pennies on the dollar.

    If the idea is to kill pigs we have to accept some non-target losses. If the idea is to make money we can keep going down the road we are on but it's like trying to kill roaches by shooting them with BB guns.

    From the Facebook posts it seems the perception is landowners are bitching about hog damage then in the sane breath asking $300 plus for the opportunity to shoot them. Myself I have no problem with poisoning them if we can do so with 100% certainty that those hunting and eating hogs won't be poisoned in the process too.

    According to the gact sheet, bords don't seem to be affected by it much.
    Mammals, not so much. It will kill mammals that feed on the carcass. Including coyotes and foxes and felines.
    Rident populations then go up. Along with snake populations. Which seem to be going up the last few years anyway.
    And every time government has tried one of these eradication programs, they have very bad consequences. Government approved does not equal it's a good thing.

    when I heard a new poison was approved, I thought it was the nitrate
    I guess that made too much sense

    Those are typically not the same land owners.

    One sees a business opportunity. The other sees a bunch of idiots that will do more damage than the hogs.

    Where you look for information can be biased with their interpretation of the data on both sides of the debate....

    "Secondary Warfarin poisoning poses a slight risk to birds and a low risk to mammals."


    The rodenticides with high secondary poisoning risks to birds such as hawks and owls include difethialone, brodifacoum, and possibly bromadiolone (see Table 3).23 The rodenticides that pose the greatest secondary poisoning risks for wild mammals, dogs and cats include chlorophacinone, diphacinone, bromadiolone, and brodifacoum. Bromethalin and cholecalciferol may pose secondary risks but these risks have not been measured.2

    Data here


    I am not supporting poisoning hogs with Warfarin. It may well be a bad idea. It may be a good idea..... However, when only presented with one side of facts, a person cannot make a sound decision. All data and their sources must be considered to make a logical rather than an emotional decision.
