What type of pesticide is used to control rodents?

The use of rodenticides is specifically designed for the control of rodents, such as rats and mice. These pesticides contain chemical formulations that disrupt normal physiological functions in rodents, leading to their death. Rodenticides can come in multiple forms, including baits, traps, and sprays, and are formulated to be effective against various rodent species.

In contrast, other types of pesticides, like insecticides, are developed to target insects, fungicides are aimed at controlling fungal pests, and herbicides are used for managing unwanted plants or weeds. Each class of pesticide serves a distinct purpose tailored to specific pests, highlighting the importance of using the correct type of pesticide for effective pest management. Therefore, rodenticides are the appropriate choice for addressing rodent issues, making this the correct answer.
