Guys at the local airport have some sort of electrical signal generator for their airplanes. It emits a relatively high frequency sound keeping rodents away, (maybe even small children). Seems to work pretty well.
Sorry I do not have more info to share, but if you are truly interested I can chase it down for you
as best I can; or try to Google the thing, perhaps. Good luck.
