In our last house Steve, I used a humane trap to catch mice. One had a little white patch of fur on his back, and the number of times I caught him are beyond telling.
I used peanuts as bait, and I reckon he came back for more!
I like mice though, sweet little things.

I always find that when one Big Spider is put outside, a second one emerges soon after. My husband calls them 'Monsieur et Madame Arraignée'!
