If there is one thing that the south has in abundance is big, weird, scary looking bugs. And, of course, snakes. Most are harmless and above all, it is a very rare occurrence that they show up with a lot of people around. Also many bugs fly so if you were on the 100th floor it might not mean anything. Even if they couldn't fly, they have this amazing ability to walk up the side of buildings, so you can run but you cannot hide.
