Is there a way to get rid of slugs?

Since we moved into our home 18 months ago, we keep getting slugs coming out at night. We have a couple in the kitchen and then the odd one in the hallway. We did try and put pellets down but now my little boy is walking i cant risk puting stuff like that down. Is there a natural way to get rid of slugs to put them off coming through the house? They seem to be getting bigger too!!! Help!
