Next on my list below humans and millionlegapedes are cave/camel crickets. You know, those huge black crickets which can jump extremely high and far, are very unpredictable, and dwell in unkempt/dark/damp/dirtfloor basements. Though I properly evict them alive (if I can catch them), I simply refuse to enter a basement where I see more than one. Doesn't help that they love the basement ceiling, able to drop onto you with no notice what so ever.
