Had a real plague of rats in the garden and have ordered two of these cases because of the good reviews and as recommended, filled with Nutella. In the first week alone, I have caught 8 rats. Now it's become much calmer, but in total have four more rats caught. The rat trap is really great. Above all, because they snapped at both small and large rats and with such a force that the animals are dead straight and having to suffer any unnecessary suffering. Can you only recommend therefore definitely !!!!
