What are rodenticides primarily used for?

Rodenticides are primarily used to kill rodents that pose a threat or nuisance in residential and commercial settings. These chemical substances are formulated to be toxic to rodents, effectively reducing their populations and minimizing the damage they can cause to structures, food supplies, and public health. The application of rodenticides is an integral part of pest control strategies tailored to manage and eliminate infestations.

While other options might seem relevant in the context of rodent management, they do not accurately reflect the primary purpose of rodenticides. For instance, preventing rodent nesting and deterring entry focus on proactive measures to keep rodents away but don't involve the lethal action of rodenticides. Attracting rodents is counterproductive to pest control goals, as the intent is to eliminate or manage existing rodent populations, rather than inviting them closer. Thus, the use of rodenticides is a targeted approach designed specifically to eradicate these pests efficiently.
