Insecticidal and disinfection apparatus using steam infusion

The present invention relates to an insecticide and sterilization apparatus and an insecticide and sterilization method for sterilizing the ground including sand etc by injecting hot steam. A lever (20) is swung up and down by an operation cylinder (10) at the rear of a self-generated power apparatus (2), is combined with a needle rod fixture (20) in which multiple needle rods (30) are arranged and fixed from side to side and is equipped with a steam generator (16) for generating hot steam capable of sterilization and insecticide and supplying the hot steam to a steam spray hole (36). The steam generator and needle rods are connected with a hose, and the hose includes steam distributors (44-1, 44-2) for supplying steam to each needle rod. The steam distributors are formed to be sealed by being connected with covers (48) and include a heating wire (49) for increasing the temperature of steam. The needle rods are moved by the operation of the self-generated power apparatus in a state in which the needle rods are buried underground. The present invention is equipped with an insecticide and sterilization operation aperture (4) including a control unit (80) for consistently injecting hot steam to the ground (6), sterilizes the ground and kills insects by infiltrating the hot steam passed through a dry process or a wet process into the ground.
