Mechanical control in pest management involves using physical methods such as traps, barriers, or manual removal to eliminate pests, while chemical control specifically refers to the use of pesticides to manage pest populations. This distinction is important as it highlights the different approaches in pest management strategies; mechanical control often emphasizes direct intervention and can be an environmentally friendly alternative to chemical solutions.

Understanding this difference is crucial for integrated pest management (IPM), where the goal is to use a combination of methods for effective pest control while minimizing harm to beneficial organisms and the environment. Chemical control can offer rapid results but may come with risks such as resistance development in pests and potential effects on non-target species. In contrast, mechanical methods often require ongoing management and may not be suitable for all pest pressures.

This accurate distinction between mechanical and chemical control methods underscores their unique roles and applications in effective pest management practices.
