BTDT, didn't work.  The suckers can smell the charge or something.

I etched a grid on a large piece of printed circuit board and
connected alternating strips to a 5kv, 1 amp plate transformer.  I put
some bait right in the center.  Turn the juice on, the rat ignored it.
Turn the juice off, he cleaned out the bait.

In the end I got him.  I rigged up a proximity detector to the bait so
the juice would not turn on until he was on the grid and touching the
bait.  BLAMO!  Blew the sucker's feet off!

Is that one of those commercially available ones where the varmint
crawls in a tunnel and gets electrocuted?  If it's like mine then
there is an optical sensor that turns on the juice only after the
booger is in on the grid.  A variation of my design, basically.

Oh that's easy to hear if you have good high frequency hearing.  I can
easily hear the harmonics of a straight unsupported filament.

Don't know.  I suspect that they can smell the ozone or maybe even
detect the electric field.  There's probably some literature on that
out there, considering how much rats have been studied.
