Which method is most effective for determining pest presence in a landscape?

Scouting and monitoring are essential practices in pest management as they provide direct observations of pest activity and plant health. This method involves systematically inspecting the landscape for signs of pests, such as their presence, damage they cause, and their life cycles. By actively keeping an eye on the landscape, a supervisor can identify pest problems early and differentiate between beneficial and harmful organisms.

Regular application of fertilizers can improve plant health and vigor, potentially reducing pest impacts, but it does not give direct insight into pest presence. Conducting soil tests is valuable for understanding soil health and nutrient levels but does not specifically indicate pest populations. Using decorative plants can enhance the aesthetic appeal of a landscape, but it does not provide any information regarding pest presence or activity. Therefore, scouting and monitoring stands out as the most proactive and effective method in determining pest presence in a landscape.
