We are flooded with mouse in the office. We bought the glue traps (but suffer, so we want to avoid) In the box is already captured at least 10 (5 this morning) that was released into a wasteland. You put a piece of chocolate for bait but it must both ensure that they have nothing more to put in the tooth (lock provisions in boxes of iron or rigid plastic) By cons we understand people who say it does not work, because at home as there are mice and there ... no one caught with this system!
