Abstract: The present invention provides a new insect pest control agent that can instantly stop the movement of an insect pest and kill the insect pest, but that does not have a risk of explosion or ignition and that does not destroy the ozone layer and that has a low global warming potential, and therefore that can be safely used. An insect pest control agent comprising 1-chloro-3,3,3-trifluoropropene as an active agent solves the above problem.

Abstract: A device (1) for spraying powdery chemical agent includes a tubular guide member (21) to be installed in a container body (11), a gas generating agent (43) to be housed in a tubular part (26), a tubular rupturing member (31) for breaking a sealing part (41) to allow the gas generating agent (43) to fall in liquid within the container body (11), a piston (63) sliding airtightly against a lower side sliding inner peripheral wall (53) and defining an air space relative to an upper side diameter-enlarged inner peripheral wall (55), and a powdery chemical agent (3) to be stored on the piston (63).

Abstract: A powdery chemical agent spraying device (1) includes a container body (11) in which water (51) is to be put; a cylindrical body (23) which is set so as to penetrate a cap (21) that covers a top opening (13) and both ends of which are present respectively in the inside and outside of the container body (11); one pair of sealing films (25,27) which seal respectively both ends of the cylindrical body (23) that is loaded with a powdery chemical agent (30) and which can be broken by the action of a pressure equal to or higher than a prescribed level; and sodium bicarbonate (41) and citric acid (43) which react with the water (51) present in the container body (11) to generate a reaction gas.
