If anyone still has problems I can recommend a watering can. Put the chocolate in the bottom, block up the spout and block 90% of the top and then build a ladder up from the ground, books are good in a house I expect you have a piece of wood they can run up. A bucket will do for a hanster but mice can jump out. Once they get in they cannot get out. I once caught three in one nigjht.
I have mice in my greenhouse at home. I have put down 2 traps and they still manage to nick the food off it, rat poison is also down and I have moved stuff around . I see one most days plus the mound of soil like mini mole hills that they dig up. Any other ideas to get rid. I am not an eco warrior so will try any method. ;D
