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

The statement is true because pesticides can indeed leave residues on untreated surfaces through various mechanisms. For instance, pesticides can drift from the target area during application, depositing on nearby surfaces that were not intended to be treated. This is known as pesticide drift and can occur due to factors such as wind or improper application techniques.

Additionally, pesticides can be transported through contact or transfer after they have been applied. For example, insects or animals can carry residues from treated to untreated areas. Even everyday activities like walking through a treated area might lead to transferring pesticides onto clothing or shoes, which could then come into contact with untreated surfaces.

Understanding the potential for pesticide residues on untreated surfaces is crucial for pest control applicators, as it underscores the importance of adhering to application guidelines and safety practices to minimize unintended exposure and environmental contamination.
