ants and more ants

We have been invaded by ants. I have spent the majority of today trying to get rid of the buggers. Does anyone out there have any homeopathic methods to keep these pesky critters at bay? Spraying Raid in my house makes me nervous because of the kids. Please help. I tried to google but the search proved to be frustrating. I kept getting product website for me to buy things to get rid of ants, I think I may not have been looking for the right thing. HELP!!!
