Hi,
Generally people carry the staph bacterium in their noses. You can use mupirocin nasal ointment (Bactroban®) inside the nose of each family member to kill the staph. It is used 2-3 times a day for a week. Everybody should use it at the same time to completely get all the staph out of the house.
