A nozzle insert (60), and/or an actuator nozzle structure, for use in dispensing a material to be dispensed from an aerosol (14) can. The nozzle insert or actuator nozzle structure divide the spray of dispensed material into two independent, simultaneously emitted aerosol streams, which have different attributes and may be emitted in different directions. One stream may be an upwardly directed fogger stream and the other stream may be a forwardly directed, aimable stream. This permits a user to direct, for example, an insecticide at a particular target, while simultaneously more generally fogging an area of interest.
