Where Did Rat Poison Come From?

Certain other rodents and fleas is difficult to kill with poison, because their eating habits reflect their place as scavengers. You will eat a little bit and wait, and if they are not sick, they go on. A good rat poison should be tasteless and odorless in lethal concentrations, and has a delayed effect.

There are several types of rodenticides available. Traditional product called anticoagulant rodenticides and are discussed here. If anyone intends to use rodenticide, we recommend you choose the kind of people because it is bidding for anticoagulant rodenticides available. others are toxic rodenticides and the antidote is not available.

In 1921, ranchers were dismayed at the sudden onset of lossage in their herds due to a strange condition: the animals bled to death. Small cuts failed to heal. The roughage cows eat will scratch their digestive systems, but unlike the normal case where such scratches are minor and readily heal, these scratches failed to heal and the animals died from internal hemorrhaging. What seemed odd was that the animals were being fed hay from fields that appeared not dissimilar from that of previous years. No sudden invasive plants of a poisonous nature had been found.

A researcher by the name of Karl Paul Link, working under the aegis of the Wisconsin Alumni Research Fund (WARF), did a careful analysis of the ensilage from ranches that suffered losses and those that did not. He discovered that a chemical, dicoumorin, found in the ensilage of sweetclover hay from those ranches suffering the losses, was a powerful anticoagulant. Dicoumarin is the result of a substance called coumarin, which is the chemical which gives new-mown hay its characteristic smell, being subjected to the heat and mold in a silo, and forming a double molecule. The year of the serious losses had been an unusually warm one after the ensilage was created.

And it is with this chemical that the modern day Rat Poisons are derieved from. They are lethal enough to kill off an entire colony of rats!

Single feed baits are chemicals sufficiently dangerous that the first dose is sufficient to kill.
