Pests fight with people for grain, harm crops and must be killed. Chemical pest control can pollute the environment, pesticide residues are produced, and foods are contaminated. Lasers are emerging science and technology, can produce hard light and cannot produce pesticidal electricity and heat, and therefore the lasers cannot directly kill the pests. However, the hard light produced by the lasers can damage ocelli, ommatea, tentacle tips and transparent mucous membranes of the pests, and therefore ganglia of the pests are damaged. A voltage-doubling small-current rectifying circuit in an electronic technology can directly achieve contact killing of the pests, a vibrator driven by an oscillating circuit produces vibration to compel the pests to shift, and a pest control device composed by means of multiple physical principles can kill a large number of the pests and does not damage the crops. According to a multiple-killing pollution-free pest killer, a physical method is adopted to kill the pests, and three kinds of damage caused by chemical pest control do not exist; the pest killer is expected to become a substitute for chemical pest control. According to the pest killer, a large number of electronic circuits and electronic elements are adopted, and the pest killer belongs to an electronic product. The pest killer is safe, clean, portable, flexible, low in use cost and capable of being used in multiple ranges and has a wide market demand.
