What is a notable feature of Anti-Coagulant rodenticides?

Anti-coagulant rodenticides are designed to work by disrupting the blood's ability to clot. When rodents ingest these substances, they interfere with the synthesis of vitamin K, which is essential for blood coagulation. As a result, internal bleeding occurs, leading to the eventual demise of the pest. This mechanism of action is a key characteristic of anti-coagulant rodenticides and helps pest control professionals understand their effectiveness and application.

The other options do not accurately reflect the properties of anti-coagulant rodenticides. For instance, they are not limited to being mixed with liquids only, nor do they exclusively originate from natural sources. They can also be effectively used in bait formulations that include food, which enhances their palatability to rodents.
