(1) The area under quarantine includes the entire state of Washington.

(2) Within the state of Washington, infested sites are subject to additional restrictions. For purposes of this hornet quarantine, "infested sites" include all real property within 20 meters of a nest containing any live life stage of hornet. After identifying an infested site, the department will attempt to notify occupants and owners of properties within the infested site that the property or a portion thereof has been designated as an infested site and is subject to additional restrictions. The designation of an infested site will remain in place until department inspectors have removed the nest and determined that the area is clear of all live life stages of hornet.
