Cal. Business and Professions Code § 8570

In addition to the officer or other individual designated as the qualifying manager for a registered company which is organized as an association or corporation, if any of the company’s other officers desire to actively engage in pest control in behalf of the association or corporation, each shall be required to qualify for and to be licensed as an operator or field representative. Nothing in this chapter shall prohibit any officer of such corporation who is duly qualified and licensed in one or more of the branches of pest control designated in Section 8560, from representing the corporation in any other branch of pest control for which the corporation is registered, except that he or she may actively engage in pest control as an operator or field representative only in the branch for which he or she is qualified and licensed. Upon being licensed as an operator or field representative, the officer may engage in pest control only on behalf of the association or corporation of which he or she is an officer, so long as he or she remains an officer thereof, but he or she may become associated with another association or corporation, or with a firm or partnership, in a capacity other than as a qualifying manager.
