PEST-REPELLING DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problems of a prescribed voltage becoming difficult to be applied between electrodes because the charge is accumulated by the capacity between the electrodes in the conventional method for applying a voltage pulse between the electrodes and electrifying a pest. SOLUTION: This pest-repelling device can apply the prescribed voltage between the electrodes 4 to electrify a termite and electrically repel the termite by periodically discharging the charge between the electrodes 4 by an applied voltage-controlling means 10 to discharge the residual voltage once when charging the voltage between the electrodes 4.
