Branch 1 of structural pest control primarily deals with which of the following?

Branch 1 of structural pest control focuses on fumigation and the control of household pests. This branch specifically addresses the management of pests that can infest residential structures, including termites, rodents, and various insects. Techniques utilized within this branch often involve chemical treatments, including fumigation, which is a common practice used to eliminate pests from a household setting.

The emphasis on household pest control is important as these pests can pose health risks, cause property damage, and create discomfort for residents. By training professionals in this specialized area, they can effectively identify, manage, and eliminate infestations to maintain safe living environments.

Other options represent different areas of pest control; for instance, agricultural pest control pertains to pests affecting crops, while pest management in commercial buildings is tailored to larger-scale operations and regulations unique to commercial structures. Lastly, inspecting pest control products is more about compliance and safety regulations rather than directly controlling pests in homes. Thus, the relevance of fumigation and household pest management solidifies the correctness of the choice concerning Branch 1's responsibilities.
