I swear by this thing, I have the classic:
What's the best way to get rid of rats? Rat Zapper!
It is called the ratzapper. It packs a wallop, here's a quick rundown on how and why I bought one.
Was standing in line at the neighborhood hardware store and they had one on the counter as a display. What you were supposed to do was turn it on and place a screwdriver through the top to the electroplate and see an arc, which is supposed to kill the rat, mouse, squirrel, etc. Guy in front of me does not believe the little arc would hurt a mouse, so Barney Fife behind the counter dares him to touch the electroplate. So while Dumb is taunting Dumber, Dumber sticks his hand in there and lets out a loud scream and flings the zapper across the store, all while letting out a long stream of 4 letter words.
I asked Barney where I could find a new one in the store and picked one up. This thing is terrific, you don't even touch the dead rodent. Bait is a bit of Peanut Butter on a 1x1 piece of paper about the thickness of a crayon box, slid all the way to the back. I've had them literally climb over their dead buddy to get the the pb, only to meet the same demise.
I no longer have a rodent problem. This is the better mouse trap.
