Yup, I contacted a company called Critter Control for my mice invasion about 6 years ago. It was driving even the daschund crazy! She would hear them in the walls and be running everywhere. I see them running across the floor, would be cleaning my counters constantly with the Clorox bleach spray because they would be on my counters leaving their crap, totally unhealthy!!! My doxie, She caught her first one the next day, and then another.
I contacted Critter Control against my DH wishes because I had enough! I have kids, and knew just like everyone what a health danger they can be! They did an inspection on the house to find out how they were getting in, I then put steel wool everywhere, they put rodenticide in the attic under the floor boards (the kind that kills the animal slowly so hopefully they go outside to die, but if not, they don't smell up the place

) and they put rodenticide feeders outside the house along routes that mice are known to follow. They would track by the amount of food gone how many mice I started out with and when the stopped. I kept them for three months, spent $270, however, NO MORE MICE!
Never had a problem afterwards either. My DH thought I was crazy hiring these guys to do this job because of their cost, but man, he wasn't singing that tune after the mice invasion stopped!
