Like everyone says, they wont do you any harm, just live and let live. If the webs get in the way, gently remove them into a large glass and put them on the earth, they will scuttle away and are more scared of you than you are of them ! If they are on the floor indoors, get a large tumbler, put it over the spider and slide a piece of card underneath gently (dont want to break their little legs) and you can then open the door and put them on the grass. In fact open the door first ... Good luck ! And please dont kill them.
