What is the primary use of acute rodenticides like Vengeance?

The primary use of acute rodenticides, such as Vengeance, is indeed for pest control. Acute rodenticides are specifically formulated to target and eliminate rodent populations that can cause significant damage to structures and pose health risks through the transmission of diseases. These substances work by causing rapid effects upon ingestion, leading to the quick death of the targeted rodent species.

In pest control, the focus is on managing unwanted animals, ensuring that the environment remains safe and free from potential threats that rodents can represent. This application is critical in various settings, including residential areas, commercial buildings, and agricultural operations, where rodents might compromise safety, hygiene, and the integrity of stored goods.

The other options are not related to the function of acute rodenticides. Soil fumigation pertains to controlling soil-borne pests and pathogens, insect control targets insects through different means, and fungicides are used to control fungal diseases in plants, which do not overlap with the usage of rodenticides.
