Any news? I used humane traps too, even filled them with cake and crunchy nut cornflake as yhey love them, but some are simply to clever.My only non-killing safe bet is to keep pet mice. Since I have mine we ve never seen any mice here again, they must sense the territory is full.
Another thing is, I am sure you are tidy but oumusg make zure there is absolute no food access whatsoevrr, such as cornflakes in plastic boxes, bread stored asay, all hamster food in plastic boxes as then the mice will get tired and look for the next zmore convenient house. Since I have pet mice I understand a lot better why it is so difficult to get rid of wild mice, mice are very clevef and they can gnaw through concrete
Good luck!
