Fixed quantity injection device for pest control

Abstract

A spraying mechanism (15) of a metered-dose-spraying device (10) for pest control has a spraying nozzle (15) having a plurality of spraying ports (37), and it is possible to perform metered-dose spraying in which a single spraying amount of a pest control agent falls within a range of 0.5 to 2.0 ml. Furthermore, in the spraying mechanism, a space around the central axis (Ax) of the spraying nozzle (15) is divided into a plurality of divided spaces so that a value obtained by equally dividing 360° by the dividing number which is the same as the number of the spraying ports (37) is the central angle around the central axis and at least one cluster (CL) of the pest control agent is made present for each of the plurality of divided spaces.
