Which factor is crucial for effective rodent control in homes?

Environmental modification is essential for effective rodent control in homes because it involves making changes to the surroundings that can help eliminate the conditions that attract and support rodent populations. This can include sealing entry points, reducing clutter, improving sanitation, and managing landscaping to minimize nesting sites and food sources. By modifying the environment to be less hospitable to rodents, homeowners can greatly reduce the likelihood of infestations.

Factors like consistent feeding, increased nesting material, and excess food supply would encourage rodent presence rather than deter them. These aspects make the environment more attractive and enable rodents to thrive, which opposes the goals of effective pest management. Thus, focusing on environmental modifications creates a long-term strategy for preventing rodent problems rather than just addressing the symptoms.
