I made Cyngbaeld's rat trap that was described in an earlier post: Brad, To make a 55 gal mouse trap start with a drum that has the top taken off. Drill 2 holes 180* apart about an inch or so below the top rim. Take a tin can with both top and bottom cut out. String the tin can on a piece of wire and thread the ends thru the two holes, leaving some slack so the can is suspended in the center of the drum's opening. Make a ramp up to the lip of the drum so the mice can run up it. Fill the drum about half way with water. Smear peanut butter on the tin can. The mice will run up and jump onto the can, which then dumps them in the water where they drown. Made it Saturday, and so far it hasn't worked. It looks like it should work. Maybe my rats don't like peanut butter. Has anyone actually had any success with one of these?
