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 entering an area falls under the category of mechanical control. This method involves physical means to eliminate or deter pests rather than relying on biological agents or chemical substances. Barriers can include items such as screens, nets, fences, or mulch that physically block pests from gaining access to plants or areas where they could cause harm.

Mechanical control is often preferable for certain situations, especially when aiming to minimize pesticide use and avoid potential environmental impacts. By implementing barriers, pest management can effectively reduce pest populations and damage while being a non-toxic approach to protection. This strategy is particularly useful in agricultural settings, gardens, and even homes where physical obstructions can provide an effective line of defense against a variety of pests.
