Mouse trap

We have had trouble with a mouse for a while in my flat. I used an empty green Ikea plastic bin and put some bird seed in it. I didn't think it would work but it was worth a shot.

I came home today and was startled by a sound from next to the wardrobe where I had left the bin. Looking for plastic behind the bin found nothing. Then I noticed a small furry thing in the bin.

Now what do I do with it? Perhaps some mouse gibbet to discourage others? Mousapult?

Here is the little fellow. And yes, it's only a baby, about a quarter the size of the other one, that's doing the most damage. The little one can jump straight up distance over 5 or 6 times it's body length.
