PROBLEM TO BE SOLVED: To provide a method for repelling indoor tarsonemidae, capable of sufficiently satisfying both the demands for high safety to human body (health) and high repelling effect against indoor tarsonemidae. SOLUTION: The method for repelling indoor tarsonemidae by spraying a stock solution comprising a mite-repelling ingredient and a solvent and a propellant, from their respectively packed containers, toward a space above a place where indoor tarsonemidae inhabit or is possible to inhabit, and thereafter, sedimenting the thus sprayed microparticles to effect their deposition on the place, is provided. In the method, the mite-repelling ingredient is a hard-to-volatile compound; the volume per shot of the spraying is 0.35-0.9 mL; and the volume ratio (the stock solution/propellant (v/v)) is (20-50):(50-80).
