Why are they here?

Question

I live with my fiance at his dad's house. We have these big ants crawling around in the house. I only see maybe 3 a day. Why are they here? Where are the little ants? I can't go around spraying pesticides since it's not my house, what else can i do to get rid of them or at least keep them out of our room. I'm scared to death of bugs! Thanks!
