We had a mouse problem a couple of weeks ago. When you think about it, they all breed over the summer and now that the cooler weather is coming on, they are looking for shelter (Dont know why it has to be in my house though....). The grey traps are definately the best as is the peanut butter. The traps are so easy and safe to set as apposed to the old wooden ones. You can also block any holes that the little buggers are coming through with steel wool.

Good Luck!!!
