Placed in my garage, it took a few weeks before the human smell disappears for the first catch. Then in 2 days 3 mice on two different traps. I went release 1 km from my home in the fields and I handed the seeds in traps for more ... Mice have already captured the history since the seeds inside are eaten but mice managed to get out afterwards. So I feed my mouse at the expense of the princess now. The trap has good springs and it must be difficult to get in for a little mouse but out there I really do not see how !!! Yet they get there and it's not by opening the lid given the weight it over there, they should have to eat a lot of spinach ... QUID! ?? until it does not work ... and do not eat my mouse poisons, help ... they are too smart. Webcam'll put a mouse over to see MacGyver in action.
