How To Get Rid of Rodents

What are ways to get rid of mice other than setting traps, getting a cat or snake?
We have set the wooden traps caught two of the mice but still got more and we leave the traps out but dont catch them. We put out the sticky gule traps again caught a few but not them all. Seems the mice get smart and learn NOT to step on them traps.
We dont want a cat, and we got a sanke but we dont let the snake out to roam our house. So thats not going to happen neither.
We have called around and was told since we have kids the best they can do is come and set mice traps for us. So thats not going to help neither. So does anyone know of any other things that will make them go away? Someone said put mothballs down and that works but i dont know. What do mice hate?
We do got a clean house I am clean freak I cant stand a dirty house. We dont leave food out neither and empty the trash daily.
Theres a mother around some where cause we keep seeing the baby mice running around.

moth balls might help but it stinks something awful, keep putting out the glue traps, one caught is a hundred that wont be born from that creature, make sure there is no food about on the floor or anything like that, because thats what they are looking for. look for holes near the foundations of your house, where water pipes come in and so on, and make sure you plug them up with plaster, calk, or something of the sort, and keep checking those areas after that because they can chew through a lot of things.
