Sealing cracks and crevices in buildings is an example of which pest management technique?

Sealing cracks and crevices in buildings is an example of physical control in pest management. This method focuses on preventing pests from entering or infesting structures by modifying the environment. Physical control techniques include barriers that can block pest access, such as screens, caulking, and other sealing materials. By effectively closing off entry points, the likelihood of pests infiltrating the building is significantly reduced, thereby contributing to a more effective overall pest management strategy.

Cultural control refers to practices that modify the environment to make it less conducive to pests, but it typically involves activities like adjusting watering practices or managing sanitary conditions. Mechanical control focuses on physical methods and tools to remove pests or prevent their spread, such as traps, but it does not inherently involve alteration of the structure itself. Biological control involves using natural enemies or predators to manage pest populations, which is not applicable in this context. Therefore, sealing cracks and crevices represents a form of physical control due to its direct impact on creating barriers against pests.
