A BVP8 protein for killing tetranychid mites and use thereof are provided. The protein is as set forth in SEQ ID NO. 2. The BVP8 protein has a median lethal concentration of 12.98 μg/mL against Tetranychus urticae, 33.45 μg/mL against Panonychus citri, and 26.32 μg/mL against Tetranychus cinnabarinus, and shows an inhibitory effect against the hatching and cleavage of Tetranychus urticae eggs, with the egg cleavage rate of 75.86% after 72 h. The protein provides a new option for the preparation of a novel miticide.
