What should be the first step in controlling a rodent infestation in and outside of buildings?

The first step in controlling a rodent infestation is exclusion. This process involves identifying and sealing potential entry points in and around buildings to prevent rodents from gaining access. Since rodents can squeeze through remarkably small spaces, it’s important to thoroughly inspect the structure for holes, cracks, and gaps, especially near utility lines, vents, and doors.

By effectively excluding rodents, you reduce their access to food and shelter, which is crucial for long-term pest management. This proactive approach is essential because once rodents have infested a space, it becomes increasingly difficult to control their population.

Following exclusion, other methods such as trapping or the use of poison can be employed as necessary. However, these methods would be more effective if the entry points are already secured, as this would prevent new rodents from entering the area during or after these control measures are applied.
