What is the maximum number of technicians that a licensed exterminator is allowed to supervise in land extermination?

The correct answer reflects the regulatory framework established for licensed exterminators overseeing technicians in land extermination practices. In Ontario, the legislation mandates that a licensed exterminator can supervise up to three technicians. This limit is in place to ensure that the supervisor can adequately oversee the work being done, maintain safety standards, and ensure compliance with all pesticide application regulations. By allowing supervision of a maximum of three technicians, the system helps maintain quality control and accountability, crucial factors in pest management and environmental safety.
