A couple of years ago I opened my front door and found a praying mantis on my screen door. I relocated it to a plant on my front porch. Next morning it (or another one that looked like it) was on the screen again. I relocated it a bit farther away on a bush at the front of the yard. Next day, guess what! Another one on the INSIDE of my screen. This one was brown, the other one was green. So I moved it to a tree in the back of the house. No more sightings on the screen door after that. I did find a small one yesterday while pulling weeds.
