Abstract: An insecticidal gun including a gun body, a feeding member, a percussion member, a trigger, and an electric drive mechanism. The gun body includes a launching chamber; the feeding member is slidably connected to the gun body and includes a material storage chamber configured to communicate with the launching chamber. The electric drive mechanism is configured to drive the percussion member to move in the launching chamber. When the percussion member is driven by the electric drive mechanism to move, the feeding member moves along the axial direction of the gun body, so that the material storage chamber communicates with the launching chamber intermittently. The trigger is rotatable with respect to the gun body to activate or inactivate the electric drive mechanism.
