I'm fortunate enough to live out in the country. All I need to do is turn my front and back porch lights on at dusk and my screen doors are covered by 10pm. I grab a large rubbermaid sweater box, place it at the bottom of the screen directly against it, and flick the screen a few times. The beetles just drop right down inside. A few try to fly out, but I can usually bat them down. Then, I pour them into a tomato sauce jar. In the morning, it's crunch-fest! The best thing is, these things hate to fly during the day. They'll dig in leaf litter pretty fast, but they won't fly away.
