I have had rats and mice invade the house periodically over the years. I can sympathyze with your plight; it really sucks to have to deal with them. Professional exterminators do a pretty darn thorough job. Get one out once and take note of their methods so you can use them when the rats come back. It seems once you have them they do keep coming back. In my case there was an 8 acre wooded lot next door that harbored them, so no matter what I did they eventually came back. Good luck, and don't fool around with this.
