The Trip Trap mousetrap we can only recommend !!! As described in the accompanying instructions, we have the mousetrap with oatmeal and raisins - Raisins were particularly well - filled (preferably at the extreme rear edge, so must your mouse over the bow which brings the door for closing climb) and late in the evening sat the first mouse in a trap. After we released the mouse alert and unharmed back into the wild, it was not long before the second mouse was trapped!
A note yet: when the mouse trap is to be installed outdoors (eg on the balcony), it works best in dry weather, in heavy rain, it may be that the "trapdoor" less than optimal closes by the wet! Otherwise, we can the criticism that the door does not close properly and should remain halfway, do not confirm and understand. Meanwhile, all the mice are trapped! A really perfectly functioning and animal friendly mousetrap!
