Using barriers to prevent pests from getting into an area is an example of which type of pest management method?

Using barriers to prevent pests from gaining access to an area is an example of mechanical control. Mechanical control methods involve physical actions taken to prevent, trap, or kill pests and can include techniques such as installing barriers, traps, or even using methods like tilling or mulching to deter pests. Barriers can be physical structures like screens, fences, or even mulch that block pest entry or movement.

This method is especially effective because it does not rely on chemicals or biological agents, making it an environmentally friendly approach. By creating a physical obstruction, mechanical control helps to maintain pest populations at manageable levels while minimizing the risk to non-target organisms and the environment. This approach can be part of an integrated pest management strategy, working in conjunction with other methods for long-term pest control.
