What type of report must only technicians and certified applicators complete?

The correct choice is a WDI report, which stands for Wood-Destroying Insect report. This type of report is specifically regulated and must be completed by trained and certified professionals, such as licensed pest control technicians and applicators. The WDI report details an inspection for wood-destroying organisms, including termites, and assesses the extent of any damage, potential infestations, and provides recommendations for treatment and prevention.

The necessity for certification stems from the technical nature of the inspection and the legal implications tied to wood-destroying insects. Only those with the proper training and qualifications can provide this report, ensuring that homebuyers, sellers, and property owners receive accurate and reliable information regarding the condition of their property.

Other options, while related to various aspects of pest control and structural evaluation, do not carry the same specific requirements for completion by certified personnel.
