We bought these becuase we had such good luck with the black flag brand and grabbed these while at the store and it has been out for about 5 days and has not caught one fly. Im not sure if I got a bad bag or what but it did not work for us sadly

It worked but this is only for outdoors the smell is very strong and bad. If not for the smell I'd give it 5 starts but the smell is so bad this is for outside not indoors.

works just as everyone says. i hardly see anymore flies outside around. they all gather and go inside the trap and cant get out. it says the bag holds up to 20,000 flies. WHOAH!!! Ive decided im gonna order another for the back porch now.

I bought 2 of these and yes it truly works wonders- it was so many flies it was totally disgusting but i rather then be in that bag then flying around me or my food - i recommend this product 100%- and i just ordered 4 more bags ,,,

This REALLY WORKS, I have several hanging at my stables and some out side my home and 1 above my trash can. Smelly but the pain is worth the gain :) Knocks down the fly population :)

Great product that really works. I put some fly paper right next to it and that's full too. Plan to buy ore Fly Traps -- a little odorous, but who cares -- flies are gone.

In two weeks, I had flies to a depth of five fingers in the bag. They just could not resist going into the trap. What's more, the flies were kept out of the house. A marvelous product, indeed.

first one worked great. hung in carport. filled with flies in 2 weeks. current one has been hanging in same location for 4 days. not one fly around it. very disappointed

I purchased one of this fly trap bags. Followed the instructions and filed it with water. When was hanging it, the plastic broke and all the water and the sfuff inside felt in the ground making a mess and leaving a horrible smell.

Didn't work. Smell didn't bother me as much as the swarm. The homemade traps from the internet worked better. Nothing in the bag. Stopped on the opening.
