Which of the following is an example of an acute rodenticide?

Cholecalciferol is classified as an acute rodenticide due to its mechanism of action and the rapid onset of its toxic effects. Unlike some anticoagulant rodenticides, which act over a longer duration and often require multiple doses to achieve lethality, cholecalciferol operates by causing an increase in calcium levels in the blood, leading to acute poisoning. The symptoms manifest relatively quickly after ingestion, which aligns with the characteristics of acute toxicity.

Understanding the different types of rodenticides is important in pest control to ensure safe and effective management of rodent populations. Acute rodenticides like cholecalciferol tend to have a swift impact, allowing for immediate interventions when dealing with infestations.
