So sorry you still have all those mice PAlady! I know how hard they can be to get rid of. Several years ago I lived in a dorm room that was infested with mice. I went home for winter break & came back & they had gotten into everything, it was so nasty. You could hear them chewing at night, and then they got bold & would come out & run across the room during the day. We had an exterminator come out & set a ton of traps, etc, which helped for a week, and then they came back... I think we killed off the local population, but others were coming in through the radiator. The building was built in the 1800's and basically hadn't been renovated since (the school also neglected to tell us that the foundation & supports were in danger of crumbling while we were living there!) & I was on the first floor which meant we had the brunt of the mice problems. Of course they completely gutted & redid the building the following year!
This might freak some people out -- but I now actually have a pet snake (he is actually very sweet, snakes have such a bad reputation, which often times is not warranted, especially for snakes raised in captivity that have had a lot of human exposure). I've had him for a few years now. He stays is his cage, but I joke that if I ever have a mouse problem again, I'll just let him out for a few days. I've never had a problem since

Coincidence? I think not!
