Do you know anything about house centipedes?

I just had a house centipede in my room about an hour ago. It had legs that spiked upward and then down and was walking pretty slow for some reason but it freaked me out really bad. I’ve been crying for about an hour and I just got to thinking, why was it in my room? Does anyone know anything about these disgusting creatures and why they are even in my house in the first place? Also, how can I catch them and ensure that they die without having to go near them? Can i set up traps?
