A friend of mine lives on a levee, lots of rodentia about..

Dogs barking all night means little sleep..

My sugestion was to find the frequency used in those mouse zappers,
build an oscillator, and crank it out of some horn tweeters over
the bank (and use a transducer to crank under the water if necessary).

Where does one find tables of such frequencies and their effects?

(CRC handbook of obnoxious electronic tricks)  :-)

Thanks!
