What is the main focus of mechanical control methods?

Mechanical control methods primarily emphasize the physical removal of invasive species and pests through hands-on techniques rather than relying on chemical applications or adjustments to the environment. These methods can include practices such as trapping, tilling, and hand-pulling weeds, which effectively reduce pest populations without the introduction of chemical substances.

This approach is particularly advantageous in integrated pest management because it minimizes environmental impact and can be safe for non-target organisms, including beneficial insects and wildlife. Physical removal methods can often provide immediate results in controlling pest populations, making them a crucial part of effective pest management strategies.

In contrast, the other options focus on processes that either involve chemicals, environmental adjustments, or monitoring rather than the direct physical intervention that characterizes mechanical control.
