1. A fogging nozzle apparatus structurally configured to be attachable to a blower and to a liquid container, the fogging nozzle comprising:
a housing including a first end and a second end, the housing including an air inlet opening at the first end to receive air from the blower, the blower being distinct from the fogging nozzle apparatus, and a fogging outlet opening to output a fog at the second end, the housing further comprising a container coupler structurally configured to removably couple the housing to the liquid container that stores a fogging liquid, and a blower coupler structurally configured to removably couple the housing to the blower;
a metered core, disposed within the housing, including a first plurality of radial angled fins configured to create a low-pressure zone within the housing as air blows from the blower through the housing, the low-pressure zone being at a lower pressure than pressure inside the liquid container such that the fogging liquid is drawn by siphon through a liquid tube from the liquid container into the housing; and
an air vortex core, disposed within the housing between the metered core and the fogging outlet opening, including a second plurality of radial angled fins to mix the fogging liquid with the air and guide the fog exiting the housing at the fogging outlet opening;
wherein the blower coupler includes a lock bar, with the lock bar configured to be attachable to the blower through a twist and lock interface, wherein the blower coupler includes a coupler ring with an inner surface having the lock bar coupled thereto and an outer surface having teeth disposed thereon, the teeth being structurally configured to mate with teeth disposed on an inside surface of the housing proximate to the air inlet opening, and the lock bar being structurally configured to mate with notches on the blower to couples the apparatus to the blower through the twist and lock interface.
