Which of the following areas should be avoided during a liquid pesticide application?

During a liquid pesticide application, it is crucial to avoid areas where pesticides can easily enter unintended locations, particularly those that can lead to contamination of water sources or impede proper drainage. Floor drains are especially critical in this context because they can carry pesticides directly into wastewater systems or groundwater, posing environmental risks and violating safety regulations.

Contrarily, outdoor gardens may be appropriate for pesticide application if managed correctly, as these areas are often the target for pest control. Storage cabinets are generally not intended for pesticide applications and are not typical treatment areas, but they don't pose the same immediate risk of contaminating water systems as floor drains. Parking lots can be treated but should be approached with caution due to runoff concerns; however, they do not present the same direct contamination issue native to floor drains.

Thus, avoiding floor drains during pesticide application is essential for environmental safety and compliance with appropriate application practices.
