Omg this is amazing! Started working immediately. It smelled bad after a few days though. But definitely getting a few more! BTW doesn't come with hook or anything to hang it up so that's why I'm giving it 4 stars.

First product I've bought that WORKS. I've had to get a 2bd one b/c I've trapped hundreds of flies with the first one. They stink, so place away from where people gather, but be ready to get rid of your flies!

Catches a lot of flies but really stinks if its disturbed but works really good . But maybe draws blow flies from the whole neighborhood lol my neighbor behind me has chickens so this helped

It stinks but works! Less flies in the house. But I think it attracts all the flies in the neighborhood! It doesn't last long. So I don't know if I can keep buying

We live on a farm and have a HUGE fly problem. Annoying flies have been driving me bonkers. I put up 5 of these bad boys in various places around the farm. They were FULL in a couple days. Ordering more now!

yes the longer you have these out the longer they start to smell like death. I use these all around my chichen run and put one in my garage to keep the files out. I'm using these under not normal situations with my chickens and they work great

Bought 2 from cal ranch worked great. Bought 1 from Walmart and it hasn't done anything. Not sure if it's just defective or what. Not impressed for the price they should work.

awesome job this bag does but i think i get every fly from miles around took 5 days for the first bag to fill up and boy does it let a rancid smell when the flies die

thet work, ir attracts the flys and kills them dead. they work for about 30 days. then I replaced them. they were filled with dead flies. my advice set them away from the patio. Or they become a conversation piece.

These things WORK, we love them, they are so easy to use, and the flies go in but they don't come out, I will never be without them now that I discover them.
