Which pest control method involves the use of natural predators?

The pest control method that involves the use of natural predators is biological control. This approach utilizes living organisms, such as predators, parasites, or pathogens, to reduce pest populations. By introducing or enhancing the presence of these natural enemies in the environment, this method aims to create a healthier ecosystem that naturally keeps pest numbers in check without the need for synthetic chemicals.

Biological control is often viewed as a sustainable approach to pest management because it emphasizes the use of natural mechanisms to maintain balance in pest populations. This method can lead to long-lasting results as natural predators can establish and reproduce in the environment, providing ongoing management of pest populations.

Other pest control methods, like chemical control, use synthetic pesticides to eliminate pests, while mechanical control involves physical barriers and traps to exclude or kill pests. Cultural control involves practices that modify the environment to reduce pest establishment, reproduction, and survival, which does not directly incorporate the use of natural predators.
