If one of these suddenly ran by you across the floor or fly by you which one would freak you out the most?

I get scorpions all the time and have had two rat snakes they I caught and put back outside, it’s illegal to kill them here where I live. I would be more concerned if a rat ran by or a rattle snake or a copperhead because we have those snakes here but I haven’t had any in the house but have seen copperheads in the back yard . We have black snakes here also and I love them. They kill and eat the copperheads and rattlers
