I have seen on the terrace a rat that has operated during the day itself at Vogelfutterhaus. I bought and installed 4 pieces of this great promise of traps. In 2 cases, I have filled Nutella and still reingesteckt a peanut in the other 2 peanut butter and as icing on the cake. After 1st night I went out expectantly. In 2 cases was ever a mouse in it. The other two have not triggered, but the peanut bait was gone. Also in the following nights always the same, from time to time a mouse but never caught the rat. However, every time the bait were eaten out without triggering the trap. The problem with the traps is that the trigger plate is simply too small, so that the rat head to Ködernapf comes without the trigger plate to touch. My summary is as follows: For mice a good case for large rats but useless !!
