What is not included in the pretreatment regulations?

The correct choice indicates that a detailed blueprint of the structure is not included in the pretreatment regulations. This is significant because pretreatment regulations generally require documentation that is directly related to the treatment process and its outcomes.

A description of the treatment performed, the number of locations treated, and the expected start and stop dates of treatment are all vital components that help ensure proper communication between pest control professionals and clients. They provide a clear record of what treatment was applied, where it occurred, and the timeline for the process, which is crucial for both accountability and follow-up assessments.

In contrast, a detailed blueprint of the structure is not necessary for compliance with these regulations. While having a layout of the building can be useful for planning treatments, it does not directly affect the legality or effectiveness of the pest control measures being undertaken as outlined in the pretreatment requirements. Thus, it stands out as the item that is not mandated within those regulations.
