Which of the following is a key factor in successfully managing rodent populations?

Sealing entry points is crucial for effectively managing rodent populations. Rodents often gain access to buildings through small gaps, cracks, and holes in walls, foundations, and around utilities. By identifying and sealing these entry points, you can significantly reduce the likelihood of rodents entering the premises and establishing a population. This proactive measure is essential because once rodents are inside, they can reproduce quickly, leading to larger infestations that are more challenging and costly to control.

In contrast, while regular feeding might unintentionally attract rodents, bright lights are not proven deterrents for all rodent species. Frequent cleaning is important for sanitation and can help minimize food sources, but it does not address the fundamental issue of how rodents access the area. Sealing entry points directly tackles the root cause of rodent infestations, making it a key factor in effective rodent management.
