Mice!!!!!!!!!!!!!

I just saw a mouse in my garage!! I thought first it was a large roach and then saw it was a small mouse. I'm freaked!! I screamed and Jason couldn't get it. Its in there, somewhere and I don't know where. Jason did tell me while he was cleaning out the garage, he found a lot of poop. Gross!! I keep all the kids toys out there, I go out there all the time barefooted, eewww I could have stepped on mice poop and didn't know it. We are going to buy traps today. I read they don't like the smell of chestnuts or fox urine. I think chestnuts will be easier to find. LOL. As long as it is only in my garage, I think I may be able to sleep.
