These are great!! I have some stray cats that I feed on my porch %26 never had flies until this summer. I had never seen so many flies! Well, I hung this up %26 there are still a few flies but about 98% off them were in this bag.

It fills up with flies very quickly, but I think it smells so bad that it actually draws flies from all over the neighborhood, making it more harmful than helpful.

These work great, they smell a bit nasty so put them a distance away from where you will be frequently, that's probably why they draw in flies. Sometimes we wonder if they are pulling in flies from the whole neighborhood to our trap.

This thing really attracts the flies and catches them. Suggestion is to put this away from your home, therefore the flies will not be close to an entrance. Also, this thing has a stinky smell that attracts the flies

Best summer purchase! Will be buying more and recommending to anyone who has a chicken coop or dog kennel. Just hang AWAY from where you want to be. Worked perfect!

This fly trap is the best, cleared my back yard of pesky fly. Now we can enjoy our back yard again as a family. Great product!! This product can have 1,000 stars!!!!

I was skeptical but let me tell you….. after 5 minutes of hanging this up, every fly and gnat was jumping to get in. So glad I bought it and you will be glad if you do too !!!!

Smelled so bad but also didn't work. 3 flies in there after a weekend and I just wanted to puke the whole time. Nothing gets to me but this ughhh I just couldn't stand it. I'll use a fan instead

I always have atleast one up on my fence line, I live next to a cotton field and have so many flies! this bag keeps them away frlm my house. its a must for me!

Amazing product! Placement is key when putting them out and they do have a pretty rancid smell but I have one by my main entrance and you only get a whiff every once in awhile so not bad
