True or False: Pesticides can leave residues even on untreated surfaces.

The statement is true because pesticides can indeed leave residues on untreated surfaces. This may happen due to several factors, such as drift during application, splashing or overspraying, or residues being carried by air currents or on the clothing of applicators. Additionally, contact with treated surfaces can transfer pesticide residues to nearby untreated surfaces. It's important for applicators to be aware of these possibilities to minimize unintended exposure and ensure that pest control measures are safe and effective.

Understanding how pesticides can move and persist in the environment emphasizes the importance of following label instructions and safety precautions during application, as well as the need for proper cleanup and monitoring afterward to protect non-target surfaces and organisms.
