Dear Steve and Shirley, I'm married and I think we have a rodent problem in our house because of my husband's friend. Let me be clear. We don't have a filthy house, and we don't eat anywhere but in our kitchen and occasionally in our living room. My husband got out of the military a few years ago and we chose to settle down in a metropolitan area. When our friends come to town, they always want to stay with us. So when my husband's friend got out of the military, he has to stay with us for a while while he looked for a house in our area. Since he's been in our home, there have been certain smells that I have never experienced before...............................................................
