For cockroach control indoors, the TEMPRID SC label and theGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Cockroaches) recommend using a coarse low-pressure spray to treat specific areas where cockroaches are active, such as entry points, feeding and hiding areas, and cracks and crevices. This targeted approach ensures effective control while minimizing pesticide use. Option B (spray entire area) is incorrect, as broadcast treatments are not recommended for cockroaches indoors; spot or crack-and-crevice treatments are more effective. Option C (coarse spray at 80 psi) is incorrect, as 80 psi is too high for indoor applications, risking overspray and dispersal of pests.
