What is one effective way to reduce rodent populations in urban areas?

Employing proper sanitation practices is an effective way to reduce rodent populations in urban areas because it directly addresses one of the primary factors that contribute to rodent infestations: food availability. By maintaining cleanliness and reducing food sources, such as accessible garbage, food spills, and clutter, urban areas can deter rodents from establishing populations. Effective sanitation involves securing trash in rodent-proof containers, promptly cleaning up food residues, and managing landscaping to minimize harborage areas.

This method not only helps in controlling existing rodent populations but also plays a crucial role in preventing future infestations, thereby contributing to long-term success in rodent management. While other methods like traps, introducing predators, or using poison bait might also address rodent issues, they may not be as sustainable or effective without the foundational practice of sanitation in place.
