you talking about the little gecko lizards? funny story, when I was in college I had a friend who had just moved down from Connecticut. so the first time he ever went to my house (which was in the boonies), he goes to open the door and sees this gecko on the porch rail near the door and starts freaking out. he is shrieking this high pitched sound and screaming, "what the *bleep* is that thing? what the *bleep* is that thing?". I was like, "what, you're telling me there aren't lizards in Connecticutt?". he said no, there aren't. it took a while to convince him that they aren't dangerous or poisonous. he said, "that's unbelievable, it's like a living freaking dinosaur". to which I replied, "um, is that more amazing than something that IS large, dangerous, and like a real dinosaur like an aligator or komodo dragon?". it's pretty funny to think back about him screaming like a little girl at a tiny little lizard.
as for catching them, don't know. they occasionally get in the house during the summer and you just chase them until you get them in a corner. they can't climb walls, so if you get them cornered it's pretty easy to catch them in your hands.
