Check out the Rat Zapper....

http://www.ratmousezapper.com/_inv/ultra.html

I have the Rat Zapper 2000.... had a minor infestation a couple years ago
through the dryer vent. Over 24 hour period, I killed 10 rats/mice. They
tell you that you may need to leave it in place for 2-3 days before mice
will be brave enough to enter. In my case, they ran into it within an
hour.
It only kills one at a time, but it is very very nice in that you don't
have mangled bodies laying around and you can simply dump the dead rat
into
the trash, pop a few chunks of dog food into it, set it down and leave it
for a while.

Found mine at Harbor Freight on sale for $30 and quite happy with it.
Neighbor used it to get rid of squirrel from his attic.

Oh.. word of advice. If you dump a dead rat into the trash, warn the
wife.

I love how they rate the battery power. 30+ rodents per set of D batteries!
That is better than my flashlight.

Which raises the question, just how much juice is required to send said
rodent to the great beyond?
