Why on earth are people being so rude and condescending to the OP? She needs help figuring out how to deal with the problem. This is not an uncommon problem. Regardless of how "dangerous" mice seem to everybody, mice are a creature we have lived right beside for all of human history. Why are there mice in so many fairytales? Why are there so many children's drawings with mouse holes in the wall? It's because mice are here beside us, whether we like them or not.
If the OP poisons the mice as everyone seems to be suggesting, they are not going to be gone for good. She already said that there is a neighborhood problem with them. They will come right back into her house eventually. She needs a deterrent such as cats or high frequency beepers in order to keep them out of a localized space. Large scale poisoning is extremely environmentally irresponsible - it kills not only mice, but all the creatures who eat them, like birds, cats and other predators. Additionally, it increases plague risk because fleas hop off of dead mice and rats and go and bite people.
Being rude and telling her that she's a bad parent and trying to make her panic are extremely unhelpful tactics. She needs support and constructive ideas. Exterminators may put a bandaid on the problem, but mice will always be around us.
