I was hesitant but this WORKS. South texas flies so annoying. Put this up & within 2 days a hugh noticeable difference. Reordered the multipack. They are good for about 3 weeks, no nasty smell, we placed it about 25 feet from our patio on a Shepard hook.
I set this item up in an area where we have a lot of flys. Followed the directions and it has been hanging in place for about two weeks. Disappointed, have not caught a single fly. I've been more effective at this point with my fly swatter.
