I have this "virgin" trap...http://www.bugspray.com/catalog/products/page1599.html

One kill, very messy if head isn't centered when activated....http://www.bugspray.com/catalog/products/page1967.html Don't let the child fool you. You need to bench over 200 lbs. to set this puppy.

Still a "virgin", but set behind the dishwasher after three drain replacements. Just waiting for the little red blinking light to flash on the remote detector. Pricey....http://www.bugspray.com/catalog/products/page791.html
