The present invention relates to the technical field of pesticides, and discloses a beta cypermethrin nano aqueous agent, the nano aqueous agent using beta cypermethrin, surfactant, and water as raw materials and not containing any organic solvent, and being made by means of a surfactant micelle solubilisation method; in the nano aqueous agent, the mass percentage of beta cypermethrin is 0.5-5%, the mass percentage of surfactant is 5-25%, and the remainder is water. The present invention uses a surfactant micelle solubilisation technique to make the nano aqueous agent, having excellent stability compared to common pesticide types, remaining stable after cold storage at 0℃ for 7 days and hot storage at 54℃ for 14 days respectively; the beta cypermethrin does not precipitate, facilitating storage and having a longer shelf life; the nano aqueous agent of the present invention has lower production costs, better quick-acting and lasting performance, will not produce adverse reactions such as pesticide damage, and
