Cholecalciferol is best described as which type of rodenticide?

Cholecalciferol is classified as an acute rodenticide because it acts quickly to cause death in rodents. Unlike anticoagulants that may require multiple feedings over several days to achieve a lethal dose, cholecalciferol disrupts calcium metabolism in the animal's body when consumed, leading to acute toxicity. The effects typically manifest within a short period after ingestion, making it effective for rapid control of rodent populations.

Acute rodenticides like cholecalciferol are designed to achieve a quick kill, which can be advantageous in situations where immediate action is necessary to control a rodent infestation. Understanding this type of rodenticide is crucial for professionals in pest control, as it impacts how and when to apply it and what safety measures to take during the application process.
