    Abstract: A method is described for emitting an insect behaviour modification signal to create a protected zone into which insect entry is minimized. The use of complex waveforms is described, emitted at frequencies from 150.000 Hz to 250.000 Hz. First and second waveforms are emitted at resonant frequencies to strengthen the protective effect. Further refinements include modulation of the transmitted signal, and frequency hopping of the transmitted signal.
