I have a problem every year during the late summer and fall with crickets 
gathering in the bushes outside my window.  It seems I once read in some 
project magazine that it is possible to repel insects such as crickets using 
ultrasonic frequency sound.  Could anyone point me to the source of a 
relatively simple circuit for doing this?  Also where to get the ultrasonic 
transducer that I presumably will need.
