What is the recommended application method for insecticides in structured settings?

The recommended application method for insecticides in structured settings is spot treatment or targeted application. This approach focuses on applying the insecticide directly to areas where pest activity is observed or anticipated, such as cracks, crevices, and nesting sites. By using this method, it minimizes the amount of product used, reduces the risk of exposure to non-target organisms, and lowers the potential for environmental contamination.

Targeted applications are more effective for controlling specific pests because they address the problem directly, leading to better results in pest management. Additionally, this method aligns with Integrated Pest Management (IPM) practices, which emphasize environmentally sound approaches and the responsible use of chemicals. In contrast, broad area spraying can lead to unnecessary product use and higher risks of off-target effects, while flooding an area with product is not only wasteful but also ineffective. Lastly, applying insecticides during high wind conditions is discouraged due to the risk of drift and reduced application accuracy.
