John's 770 Volt Rat Trap (K) Kopylepht 1970,1997 When I was a kid, the city decided to fill in a ditch behind our property, replacing it with a buried drain pipe. This had an upside (better drainage) and a downside - the rats that lived in the ditch started coming into the neighborhood basements. Well, we had an old house back then with a basement, actually more like a really big crawl space, which could only be accessed from outside. No matter what we did, we couldn't keep the rats out, though. So, my dad came up with a great idea. What he did was he got a 770 volt plate transformer from an old radio, and connected one side of the secondary to ground (a copper pipe in the clay under the house) and the other side to a cookie sheet. The cookie sheet was insulated from the ground by a couple of plastic-wrapped bricks. On the cookie sheet, dad put some cheese, peanut butter, other foods that might set a rat's mouth watering. Then he plugged the plate transformer in - the transformer's primary was 110 volts. Within 20 minutes he had his first kill. When a really big rat fell for the trap, it would momentarily dim the lights in the house! Within a week no more rats were being caught - either they wised up or we killed them all; we'll never know. The downside to this was disposing of the bodies. Very few things smell worse than burning rat hair. The rat's front feet are usually burned up too. Needless to say, this was done far away from anything combustible. Kids, don't try this at home unless you know what 770 volts will do to you when you fuck up.
