What is an effective example of pest-proofing?

An effective example of pest-proofing is applying a sealant around pipes. This tactic helps to prevent pests such as rodents and insects from entering a structure by sealing off potential entry points. By addressing these vulnerabilities, you can significantly reduce the chances of infestations before they occur. This proactive approach is fundamental in pest management, as it focuses on physical barriers rather than solely relying on chemical treatments.

The other options suggest reactive measures rather than preventative ones. For example, using pesticides in open areas or spraying insecticides outdoors treats existing pest problems but does not prevent new ones from entering. Similarly, using traps in every room may capture some pests but does not address the root cause of their entry into the home.
