The invention relates to a method and to a device for repelling insects by means of a two-channel pulse pattern transmitter (1), which, by means of the integrated antennas (34a, 34b), emits two electromagnetic waves (35a, 36a) phase-shifted against each other by 180 degrees and modulated and pulsed with the pulse patterns (24, 23) and produces two electromagnetic fields (35b, 36b), which act on insects (45) located in the radiation range (76) in such a way that the neurons (50, 53) located in the supraesophageal and subesophageal ganglia (48, 51) and the sensory neurons (65), the motor neurons (66), and the interneurons that exist in the central and peripheral nervous system (63, 64) of bloodsucking insects (45) are influenced in such a way that the signals and reflexes produced by the neurons trigger abnormal behaviors that put the insects into an inactive state such that bloodsucking insects cannot penetrate the skin of humans and thus cannot suck blood.
