Once I had all the traps with different baits, I unfortunately had to find that no, neither the snap traps were still working this live event.
Shockingly, however, was that I could see that the mouse or mice had "visited" the live trap. There were tons of mice droppings namely in the case. Mice itself however not. Which had somehow managed to escape. The only explanation that I had it was that she had somehow managed to force open the lid of the case and to escape it (added very adventurous). So I created the cover for the next test so complained that he could be squashed. At least not by a mouse. The result was the same allerdinsg. Mice droppings in the case, but again no mouse. Can only mean she or they have managed again to escape. So either I have particularly clever mice or the trap is not working. But I tend towards the latter assumption. So rather not buy recommendation.
Ultimately a snap trap has been successful. Pity about the mouse. In sports terms what she had earned another. So rather just a star!
