I don't have a mouse problem, but I can send you a few rats to amuse the dog, and ease your conscience. I noticed yesterday that I had droppings in one of the feeders. They're BAAAACK!
I read something on one of the threads that I'd like to try. They were saying that a colony of rats/mice send out a sentinel to test the new food. If the sentinel dies, the rest won't eat the food. They said to make dough balls from flour, a little confectioners sugar, and just enough oil to bind it all together. Feed this to the rats for a week. As they discover it's safe, more of them will come to eat it. Just keep adding more, and more as needed, for a week to 10 days to ensure the whole colony is eating them. Then after 7 - 10 days, add in dry plaster-of-paris to the mixture. They won't notice it, and it will kill the whole colony. An added bonus is that it won't poison an animal that might try to eat the dead rat.
