Little mouse trapped

Here's the mouse I caught the other day. It was in my garage, hidden in a pile of wood.
The dog noticed it and started barking until I saw the mouse run away.
So I set this trap with some treats inside.
The next morning I found the mouse inside.
This trap is really nice because you can then release the mouse into the countryside.
I don't want to kill it, but I don't want to have it in my house!
What do you do when you find a mouse?
