Bests & Worsts Reviews from Amazon

Urban I have to say that this thing catches a lot of flies. The first day it caught fifty and after that it ramped up quickly to two or three hundred a day. But if you live in a city like I do you may not be able to get this thing far enough away from you. The instructions tell you to place it at least 35 feet from the area that you use. But 50 feet is probably better, as the flies are gathering in heavy numbers within 15 feet of the bait. After a few day the bait smell is also obvious at that distance. So if you have a large backyard (I do not) put the trap in the farthest corner. Or if you don't like your neighbors... PETS The bait is a smelly powdered protein meal that reminds me of dog kibble. My dog went on a sniffing frenzy when I received the box. She is also lured to the hanging bait. So if you have pets make sure they can't reach it. It's not toxic, but believe me, you wouldn't want to clean that mess. FLIES As far as the fly types it catches in my yard, 99.9% are green bottle and blue bottle flies (AKA blow flies) and a few house flies. I have observed many flesh flies lured to it but the trap cover has too narrow a gap for them to enter comfortably. You could leave the top off I suppose but the added water would evaporate quicker in the recommended direct sun. Other extremely tiny fly types I could not identify were also lured but in very few numbers. Yes I spent a lot of time staring at the trap. Update: 2016 Living in the SF East Bay now. Previous owner of new house had put down wood chip mulch on 75% of the back yard. During this last El Niño the subsurface mulch was pretty moist and attracting thousands of blow flies. My better half didn't even want to go to the back yard. So ordered up a FBG Trap and let it do its job. It took a few days to really kick in because the weather was cold but now that warmer spring weather is here the flies are lining up like planes at an airport ready to land. I'm serious, I can just stand there and watch them land and crawl right on in. If they only knew. So I'm happy to report there's not a fly in sight, except for those coming in for an extended stay and my wife can go outside now. And... I still stare at it. Can't help it. It's hypnotic.
