Sealing cracks in a building is an example of what type of mechanical control?

1. Trapping

2. Exclusion

3. Cultivation

4. Cultural

The correct answer is: Exclusion

Sealing cracks in a building is an example of exclusion because it directly prevents pests from entering a structure. Exclusion is a proactive mechanical control strategy aimed at blocking entry points for pests, thereby reducing potential infestations. By sealing these cracks and openings, you create a barrier that deters insects and rodents from gaining access to indoor environments, effectively minimizing the need for chemical treatments and contributing to pest management efforts. Other control options, such as trapping and cultivation, focus on different methodologies and are not primarily about preventing access. Trapping involves capturing pests that are already present, while cultivation refers to agricultural practices aimed at managing pest populations through changes in the environment or crops. Cultural practices encompass a broader scope, focusing on modifying human behavior and practices to prevent pest problems but do not specifically target physical entry points like exclusion does.
