Is mosquito responding to electromagnetic waves?

Last week I visited a place that was having more mosquitos.They are using mosquito bate that produces high frequency and high voltage electricity .Without its physical contacts as soon as the electrical appliance is switched on the mosquitos are flying away from the place. Where as no sound is produced by the bat.I suspect this may be the cause how the mosquitos are disappearing from tha place before earthquake affect the place. Am I correct in my idea? It senses the electromagnetic waves produced before earthquakes because of slipping of tectonic plates.
