We started it in the fall and still caught tons of flies. It smells pretty gross and attracts a lot of flies so keep it as far from the area you want to help as possible.

I was astonished by how many flies this thing caught and killed! Simple to use. The only thing I don't really care for is the odor of death that it emanates after a couple of days of trapping flies

Very easy set up, simple design, very effective. Reasonable price. Have Four of them within 50 feet of cow pen and keeps flies away from house and deck. Once bag is full close up and put in garbage.

We have a lot if horses and donkeys, which means a lot of flies. These attract and kill 1000s of flies. only downside....water does need to be re added due to evaporation. Raccoons and bears also like the smell, so these attract them too

Its only middle of June, and I have gone through two traps already. Make sure you set it away from your house. Has a distinct sewer smell, but it works Wonderful.

I can live without this product. I set one at the front %26 back door at instructed distance. I live in the country with pets in and out all day. This product smells like bad chicken.Thats why u put some distance from house.

This really attracts flys away from my back door, since putting this up only 1 fly has gotten in my house. the only reason why it doesn't get 5 stars, is because it does not have a pleasant smell.

Other than the smell (to attract flies obvi) which we hung farther away from our house to not smell and also to lure the flies away as far as possible. Within a couple days, none is sight!! Love these and will continue to buy

This product attracts flies and traps them! It works! After a few weeks it smells bad and looks gross with all the dead flies so you should replace often. But it works!

This thing is amazing! I honestly didn't think anything could get rid of the fly problem in my yard but this bag did it!! I couldn't wait to go but more and the price is good too!! No complaints!!
