PROBLEM TO BE SOLVED: To provide an aerosol product and an insect pest control method in which sticking to an object at the inside of a chamber is suppressed, and an object is hard to be contaminated.SOLUTION: Provided is an aerosol product filled with an undiluted solution including an insecticidal component(s) and an aerosol composition including a propellant, in which a nozzle hole is formed, the undiluted solution does not include a solvent or includes an aerosol solvent in which an octanol/water partition coefficient Log Pow is 8.0 or lower, the insecticidal component(s) includes at least one selected from the group consisting of transfluthrin, metofluthrin, profluthrin and metofluthrin, the blending ratio (mass ratio) between the undiluted solution and the propellant is (1/99) to (16/84), and the 50% average particle diameter based on the volume cumulative distribution of the jetted aerosol composition at a position separated by 50 cm from the nozzle hole is 20 μm or lower.SELECTED DRAWING: None【課題】室内の対象物への付着が抑制され、対象物を汚染しにくいエアゾール製品および害虫防除方法を提供する。【解決手段】殺虫成分を含む原液と噴射剤とを含むエアゾール組成物が充填され、噴口が形成され、原液は溶剤を含まないかオクタノール／水分配係数Ｌｏｇ Ｐｏｗが８．０以下であるエアゾール溶剤を含み、殺虫成分は、トランスフルトリン、メトフルトリン、プロフルトリン、メパフルトリンからなる群から選択される少なくとも１つを含み、原液と噴射剤との配合割合（質量比）は１／９９～１６／８４であり、噴口から５０ｃｍ離れた位置における、噴射されたエアゾール組成物の体積積算分布に基づく５０％平均粒子径は２０μｍ以下であるエアゾール製品。【選択図】なし
