Method for spraying anti-termite agent and the apparatus therefor

摘要

A spray nozzle for spraying anti-termite agent has a base portion including a supply portion having a generally cylindrical shape and being formed with one or a plurality of jetting ports at one side end in the axial direction of the supply portion, and a horn portion having one end portion attached to the jetting ports side of the base portion. The horn portion has a plurality of air suction holes peripherally at an adjacent position where the jetting ports are situated about the axial direction thereof, and air is sucked by utilizing the Venturi effect of jet streams of the agent in order to spray the agent in bubble form.
