Which of the following is a typical component of a pest-proofing strategy?

Implementing preventive sealant measures is a fundamental aspect of a pest-proofing strategy because it focuses on preventing pests from entering a structure in the first place. This proactive approach involves sealing cracks, gaps, and entry points that pests may use to gain access. By eliminating these vulnerabilities, the likelihood of future infestations is significantly reduced, which is more effective and sustainable than waiting until pests have already invaded.

This strategy is part of an integrated pest management (IPM) approach, emphasizing long-term prevention rather than short-term fixes. Preventive measures can include sealing windows, doors, and ventilation systems, as well as using materials that deter pests from entering, thus enhancing the overall integrity of the building.

Other options may involve responses to active infestations or reliance on chemical treatments, which do not address the root cause of pest entry and reliance on ongoing treatments can be costly and carry health risks. Implementing preventive sealant measures is a more strategic and health-conscious method to maintain a pest-free environment.
