The present invention relates to the technical field of pesticides, and disclosed thereby is a high-efficiency cyhalothrin nano aqueous solution, the nano aqueous solution uses high-efficiency cyhalothrin, a surfactant and water as raw materials, and is made by using a surfactant micelle solubilization method without adding any organic solvent. The mass percentage content of the high-efficiency cyhalothrin is 0.5-10%, the mass percentage content of the surfactant is 5-20%, and the remainder being water. The present invention uses a surfactant micelle solubilization method to make a nano aqueous solution which, in comparison to a conventional pesticide formulation, has excellent stability, and is still stable after cold storage at 0°C for 7 d and hot storage at 54°C for 14 d, respectively. The high-efficiency cyhalothrin nano aqueous solution will not separate, is convenient to store, and has a longer shelf life. The nano aqueous solution of the present invention has relatively low production costs and is even
