A pest control business must cease operation regarding structural pest control when it loses its only certified technician. This is crucial because pest control operations are regulated by specific certification standards that ensure safety and compliance with state laws. If a business does not have a certified technician on staff, it cannot legally conduct pest control services, as there would be no qualified individual to oversee and execute the necessary treatments in compliance with regulatory requirements. This scenario safeguards public health and safety by ensuring that only trained professionals handle pest control, which involves the use of potentially hazardous chemicals and techniques.

In situations where a business has only one technician certified, losing them can create an immediate need to pause operations until another certified technician can be obtained. This underscores the importance of maintaining credentialed staff to adhere to legal and safety standards in the industry.
