Geckos seem to like us:

Saw that one on our back door a couple weeks ago.

We found a few tiny baby geckos inside, barely an inch and a half long including the tail. Apparently they like to squeeze into tiny crevices to hide during the day, like the gap in the doorframe weatherstripping I found.

I found another baby one last night in the bathroom, caught it with a container and sheet of paper, put it outside. Unfortunately the big guy was hanging out on the door again, but not on the window part.

So he fell off the the door inside and ran under the couch, and we spent almost half an hour moving furniture and trying to catch it before we lost it completely.

So we've got a full grown gecko hiding somewhere in the house. I'm not a fan of letting wildlife in the house. I would definitely rather keep the grown lizards on the outside. But it doesn't bother me too much to return a lost baby gecko outside, or if a few crane flys and jumping spiders get in in spring, and nobody likes cockroaches but we've had less than one per week all summer. I think we're doing great. Do you really expect nothing to get inside?

My wife was pretty freaked out even before yesterday though, so hopefully we find it soon and not months from now.
