The insecticidal mat comprises a fibrous mat having a size of 1,000 to 2,500 mm2 which contains 250 to 600 mg of allethrin as an insecticidal ingredient, 600 to 1,000 mg of piperonyl butoxide as a volatilization controlling agent and 10 to 100 mg of at least one member selected from the group consisting of 2,5-di-t-butylhydroquinone, 3,5-di-t-hydoxytoluene and 3-t-butyl-4-hydroxyanisole as a volatilization controlling agent per mat, wherein the mat is used by setting on a radiation plate which has an area of 1,000 to 2,500 mm2, has a temperature of 150 to 190° C. at its central portion, and has a temperature difference between the central portion and its edge portion of 10° C. or less.

Abstract: The present invention provides a delayed spray actuator for aerosol which is convenient for a user at the time of an ejection operation, that is simple in the entire construction, and that elongates a delayed time period. When a valve member 1 is depressed, the valve member 1, a cover member 5 and a stem 1 are moved downwardly to open a valve portion of the stem 10 and an outer sheath portion 7 is held in a state in which a protruded portion 7a thereof is engaged with a protruded portion 15c of a cover body 15. In this state, an end portion of a skirt portion 4c of a sheath-like responding portion 4 is closely contacted with a small diameter portion 6b of an inner circumferential surface of an inner cylinder portion 6, and a flow passage defined by a hole portion 6e, a groove portion 4b, and an output side hole portion 2a is closed.
