PURPOSE:An insecticidal propellant having extremely improved properties with respect to a countermeasure of resistance, obtained by using a compound agent of a pyrethroid and a carbamate agent, and an ethylene glycol monoalkyl ether solvent having a specific boiling point, etc. as a solvent for preparing an insecticidal stock solution. CONSTITUTION:An insecticidal propellant obtained by packing a content consisting of <=10wt% insecticidal stock solution obtained by adding an ethylene glycol monoalkyl ether or an ethylene glycol dialkyl ether solvent (e.g., methyl Cellosolve, etc.) having >=80 deg.C boiling point as a solvent for preparing an insecti cidal stock solution to a mixture of a pyrethroid shown by the formula (X is methyl or chloro; R is H or cyano) and a carbamate compound [preferably 3-(2-methoxyphenyl)-5-methyxy-1,3,4,-oxadiazol-2-one] and >=90wt% incombustible propellant into a pressure container at an inner pressure of 3.0-7.0kg/cm<2>/25 deg.C, and attaching a valve to jet the whole amount of the content at >=1ml per second to the pressure container.
