Which of the following is important to stress to homeowners for effective rodent control?

Focusing on sanitary measures is crucial for effective rodent control, as it directly influences the likelihood of rodent infestations. Rodents are attracted to areas where they can find food, water, and nesting materials. By emphasizing the importance of maintaining cleanliness and proper sanitation, homeowners can eliminate potential food sources such as crumbs and spills, secure waste disposal, and store food in rodent-proof containers. This reduces the chances of attracting rodents to the property in the first place.

While other options touch on aspects of rodent management, they do not address the fundamental behavior of rodents as directly as sanitary measures do. For instance, reducing noise levels might limit disturbances but does little to actually deter rodent presence. Increasing the number of traps could help in capturing rodents if they are already present, but it does not prevent the initial attraction. Discussing habitats is important in understanding where rodents may live, but without addressing sanitation, the issue is unlikely to be resolved effectively.
