I had a friend in for coffee yesterday and there was a big horrible fly in my livingroom, grrrrr! We had a discussion about flies (nice) and I mentioned I had killed two already in the morning. My friend told me that she doesn't bother killing them and just leaves them 'till they die themselves? I thought they laid millions of eggs if left to their own devices and were better to be killed?
What do you do with the blighters.
