What is an example of a physical pest control method?

Using traps or barriers is a prime example of a physical pest control method. This approach involves utilizing tangible items or structures to prevent pests from accessing certain areas or to capture them. Traps can capture pests like rodents or insects, while barriers such as fences or row covers can physically block pests from reaching crops. This method is advantageous as it doesn't rely on chemicals, making it safer for the environment and non-target organisms.

In contrast, chemical sprays utilize pesticides to eliminate pests, while planting resistant crop varieties involves genetic modification or selective breeding to create plants that naturally resist certain pests. Applying organic fertilizers is unrelated to pest control and focuses on enhancing soil fertility rather than managing pest populations.
