What do I need to do to rid my home of head Lice?

So my head was starting to itch a little and I though it was from being out in the sun and I got a sun burn on the back of my neck and around my ears and top of head. Anyways I was at a friends house at a pool party with the kids and Family together, she called me today and told me that her daughter came down with head lice.....I need to know what I need to do with getting rid of them. I haven't seen any eggs or lice in my hair or my sons, but what to treat my house as if I had them so if I do I can get rid of them before they start. Add when treating my hair does Mayo really work? Thanks
