They eat bugs... they are working for you. Don't kill them on purpose please. They really want to live with us in peace. They only fang you when they get confused or are hurt.
They typically don't want to be in your house unless they plan to make a nest. Which you obviously don't want. So if they are in the house you can kill them. Thats good too because eventually they will learn to stop coming in the house.
