These things must give off some kind of pheromone that attracts and disorients the biggest horseflies I’ve ever seen.
My daughter gave me one a few years ago and we had flies from six counties trying to get into that thing.
They would fly like they were drunk and seemed to have absolutely no will to escape capture.
I don’t remember it actually catching one before we got rid of it.

Would have worked better out in the barn!
