(Solved) How Do Anticoagulants Kill Rodents?

Anticoagulants work by preventing the assimilation of vitamin K1, one of 12 ‘blood clotting factors’ within vertebrates 👍 Once a lethal dose of poison has been eaten by the rodent, there is a lag period while the existing vitamin K1 in the body is used up 🙌 This normally takes three to four days, after which the blood will no longer be able to clot, and any haemorrhaging inside the body will lead to death. The great advantage of the lag period is that rodents never associate the bait’they’re eatingating, with the symptoms of poisoning they go through. This means it is possible to attain 100% control of the population, as the rats will continue to feed on the bait ignorant of the fact it is killing them.
In studies with bromadiolone baits applied to soil, 45-78% of the had bromadiolone broken down in the first 21 days. Some studies indicate that it may take longer to break down if stored underground by animals where it has less exposure to the weather. Bromadiolone has a low potential to move in soil. When it was tested in four different soil types, 95% was found in the upper three centimeters. However, it was more mobile in sandy soil. In water, a half-life of 392 days has been reported. However, in some water conditions bromadiolone may not break down. Bromadiolone has a low potential to move up into the air. (last emended 3 weeks ago by Latori Martin from Gothenburg, Sweden)

Npic.orst.edu goes on to describe how rodents, humans, dogs and cats are all mammals, so our bodies work in very similar ways. Rodenticides have the same effect when eaten by any mammal. They can also affect birds. Rodenticides are usually formulated as baits, which are designed to attract animals. Flavorings may include fish oil, molasses or peanut butter. Baits used in agriculture and natural areas may contain ground meat, vegetables, grains, or fruits.2 These may be attractive to children and pets, so they should never be used or stored within their reach. Tamper-resistant bait stations make it even more difficult for accidents to happen. For ways to prevent exposures to children, pets, and wildlife, see the information below about what you can do to reduce risks. (thanks a ton to Torren Redding for their insight).
All these birds were victims of “second-generation anticoagulant rodenticides” used by exterminators, farmers, and homeowners. They’re found in such brand names as d-Con, Hot Shot, Generation, Talon, and Havoc, and they sell briskly because of our consuming hatred of rats and mice. The most pestiferous species are alien to the New World and therefore displace native wildlife; they contaminate our food and spread disease. We also hate them for their beady eyes, their naked tails, and their vile depictions in literature, from Aesop to E.B. White. So the general attitude among the public is “if a little poison’s good, a lot’s better.” But even a little second-generation rodenticide kills nontarget wildlife.
