Mechanical controls play a crucial role in Integrated Pest Management (IPM) by employing physical methods to manage pest populations without relying on chemical interventions. The utilization of mechanical controls involves strategies that directly disrupt the life cycle or behavior of pests. For example, traps can be used to capture pests, barriers can prevent pests from accessing crops, and hand-picking can effectively reduce pest numbers in small-scale situations. This method aligns with IPM principles as it seeks to minimize reliance on chemicals, thus leading to more sustainable pest management practices.

In contrast, applying herbicides is a chemical-based approach, which does not fit the mechanical control category. The introduction of beneficial insects is a biological control strategy, not mechanical. Implementing crop insurance policies addresses economic risks associated with pest damage but does not involve physical control methods for pests.
