It occurs to me that I could put my blacklight on the ceiling. The bugs would go there, and so would the lizard...but my cats would be unable to resist the earth's pull enough to pounce on him. Also, I could catch him with a bucket.
My only concern is: can a skink crawl on the ceiling? I think geckoes can, but what about skinks...?
Siv: Perhaps, but that approach didn't help me get Madonna out of my house. They're always too smart for that.
