I've had it out a week now and no rats trapped.  They've been in it...  One day I found it flipped over, another day found the light blinking, but no rats.  The fire ants sure do love the peanut butter I put in there though.

UPDATE:  We did manage to catch 1 rat but It finally went in the garbage.  Several mornings in a row found it with the blinking light on like it caught something, but nothing in the trap.  Looking more closely inside the trap I could see sparks flying.  Not sure what happened, if humidity tripped it?  I did have a camera on it all night and saw no animals going in.  But the fact that it tripped itself and had hot sparks jumping seems very very unsafe.
