A mouse in the house!!

We have a furry visitor in our house. It seems confinded to our lounge, so we are ensuring we are closing doors behind us in an attempt to keep it confined to the one room.
Ive had humane traps down, but its not been tempted to go in. We put the usual mouse traps down last night. It ate the cheese and choc....but the traps didnt go off!
Clever mouse!
