The trap works great, did just as advertised. The only problems I had with it was it's unsightly after you have it up for two weeks. It's gross to see all those dead flies but mostly it started to smell terrible. We had it about 40 feet from our pavilion. But it did work so if you had it some place out of the way it would be great.
Ordered two of these. Tried 1 week later still no more flies than would have been attracted to bag of water. when i tried to give the second a try before trying to get a refund i put in pinch of dirt and filled it with water from duck pond. BINGO . 2 days later in the nevada heat works like a charm . refilled 1st one with it too. they are smelly though so keep them away .
Okay I get it, once there are decomposing flies inside. But the smell is intolerable if it's anywhere near say the patio where you don't want flies. If you can place it more than 25 feet away it will be useful.
