All logic circuity of course. You still need power driver . I was try to use TDA2822M (suitable up to 100kHz; use 100nF caps only instead of reccomended!) which was pretty hot at Vcc=12V but still OK for many weeks in continous load.

New version made from more advanced solution have 8 selectable modes for different kinds of animals/pests.
