We have had mice running around our home for over three months now. The exterminator has been here 3 times but cannot figure out how they are gettibg in. I am scared to death of the little creatures and have now even seen some huge ones. (I don't think they are rats!) We have poison everywhere but the population just increases daily. I have 4 children under 7 who think this whole thing is funny but I do not. Any suggestions? By the way glue pads are out of the question as they are no longer available here.
