We found a baby mouse outside our back door last night, it had been hurt and was dead by this morning. Then when we came home this afternoon there was one on the drive, I think ds had trod on it because this one was lying on its side. I then dawned on me that they were living with us! I had put in the garage a large sack of bird seed (left over from making reindeer food for the school at christmas), this bag has been torn at the bottom and the seed has spilled out, now we realise the mice have done it, we thought I had done it when I put the gardening fork away. On inspection I saw another mouse scurring away. So thats certainly three. Whats the best and quickest way to deal with them and how long before I can be sure they have gone away. We have thrown out the seed now and have swept up.
