As stated elsewhere it takes a day or two to get going, and it does smell but it did not smell as bad as we were prepared for it to. It has lasted all of a week and has caught thousands. I have to throw it out as there is no room for flies to go into the bag.

My only recommendation is if you have a lot of flies go for the quart(M380) or gallon(M383) product that is reusable and can be re-baited.

The best product for easily catching and killing outdoor flies in summer. Using it will also cut down on future flies. I see some one- and two-star reviews and the only explanation for the product not working is that the instructions were not read and followed. I have to buy it through Amazon because my local stores can't keep these in stock. Add warm water to the plastic bag, and give a little light shake to mix the powder solution into the water, then hang up outside. You will be shocked at the number of flies it catches and kills. Also, in my yard, because so many flies were exterminated it cut down on the future fly population that would have resulted from reproduction. The product does stink, and that's what attracts the flies so don't hang it near the BBG grill. The hanging catcher also is easily disposed of - be sure to snap down the yellow plastic top into the holes and the bag will be sealed for throwing into the garbage. Also be sure to replace with a new fly magnet at some point because there will be too many dead flies in the liquid for the scent to still be attracting new flies. Most importantly, Read All The Instructions. Buy the fly magnet, and take back your backyard.
