There seems to be an invasion of Ladybugs and Box Elder Bugs here in the Midwest. They're not harmful, but they become annoying, sometimes flying right into one's face, laptop screen, or nearby light source.
According to the ever-resourceful wikipedia though, Ladybirds or Ladybugs can be beneficial:
"In parts of Northern Europe, tradition says you get a wish granted if a ladybug lands on you. In Italy it is said by some, that if a Ladybird or Ladybug flies into your bedroom, that it is considered good luck."Perhaps they're not so much of a pest after all.
