If it's gonna live at my place it better pay the rent. 
Tbh I don't mind spiders as long as they sit in a corner of the room far away from me. There's not a lot of deathly spiders where I live. Just sometimes there's a bigger one and that I'll usually get rid of because there are arachnophobes in my house.
Anyway, someone correct me if I'm wrong, but aren't all spiders venomous but not all of them have enough venom to harm a human?
