Yeah, that would creep me out too.
Tarantulas, at least the ones around here so I've been told, are harmless, they're just so darn ugly, and big, and fuzzy:) I don't know if it's the flowers that attract them to the garden or just the fact that the flowers provide more cover then the bare patio. Maybe they didn't use to come up here because of the big open space.
I ride alot out in the woods here, and am always worried one will fall out of a tree. Or any bug for that matter. I can deal with snakes and mice better then bugs. Bugs scare me:) I've had stick bugs fall out of trees. So far they have never landed on me, just the horse...but that's bad enough. Stick bugs and praying mantis's are other bugs I think are down right ugly and gross:)
