If you didn't introduce them and you have ladybugs, you most likely have an aphid or mite problem. They wouldn't be there if there wasn't food. But now that you have them, cater to them. Alot of us want them but we can't get 'em 'cuz they are out of season. Another critter you might look into is the Praying Mantis. They eat a shitload of destructive bugs, and supposedly, they bring good luck to a house when they are inside. It IS kinda creepy to open your eyes in the morning and have a Mantis right there on the pillow staring you down.
Yes... umm... ladybugs are a little bit less intimidating. Of course any insect with wings creeps me out.
