What action should be taken if rodents are frequently observed in traps?

Choosing to evaluate and modify exclusion methods is essential when there is frequent observation of rodents in traps. This indicates that the current methods of keeping rodents out of a particular area are not effective. Exclusion methods involve sealing entry points and creating barriers to prevent rodents from accessing a space. By reassessing these strategies, you can identify potential vulnerabilities such as gaps, holes, or other openings that might allow rodents to enter despite trapping efforts.

Enhancing exclusion methods also addresses the root cause of the rodent issue rather than only managing the symptoms. If rodents can still get into the area, merely increasing the number of traps or changing bait will not resolve the underlying problem leading to continued infestations. Therefore, focusing on exclusion is a proactive approach that can lead to a more sustainable solution in controlling rodent populations.
