Why are pesticides applied more often for structural pest control compared to agricultural pest control?

The application of pesticides more frequently for structural pest control can be attributed to the nature of pest management in that domain. In structural pest control, pests such as termites, rodents, and various insects can invade homes and buildings, creating immediate health, safety, and economic concerns. When structural pests are detected, action thresholds—the point at which pest populations require control measures—are often exceeded more quickly due to the proximity of these pests to human living and working spaces.

The urgency to protect human health and property from infestations drives pest management professionals to respond promptly and aggressively, often resulting in more frequent pesticide applications compared to agricultural pest control, where thresholds for action may allow for more gradual responses. In agriculture, pest management tends to focus on economic damage and the broader ecological impacts, allowing for a more measured approach that considers various control methods, including integrated pest management (IPM) strategies that may reduce the reliance on pesticides.

Thus, the context of structural pest control—where the need for immediate eradication can lead to more rapid decisions about pesticide use—is the reason for the higher frequency of application in this field.
