There is a smell…. But it works amazingly. I will be buying more. All the black in the bottom of the bag are dead flys!! And I like that when it is done I just throw it away . Well worth the money!!

This thing not only caught all the flies that have been living in my backyard, but it's now killing all of the other flies in the neighborhood. I'm buying another with the hopes that nobody gets bothered all summer lol

I purchased 2 of these to catch an over abundance of flies in my yard. The directions and set up are pretty straight forward. It does have a pretty bad smell but in all honesty it wasn't constant.

These things are amazing and stink horribly. I see why the flies are attracted. Put them away from your sitting area and don't accidentally drop one in the house. Omg!!! Lesson learned. Within a hour the bag had many quest that didn't leave. lol

This is a wonderful product and it holds the flies in. It does smell pretty bad after a few days but that is what draws the flies. I don't recommend sitting next to it..lol.

It definitely attracted flies and it worked wonderfully with trapping them, however the smell is terrible! On the bright side our home hasn't seen a fly since summer began.

I highly recommend this product really attracts thousands of flies starts working right away best on the market I have been using this product for years

[This review was collected as part of a promotion.] I just started using it to amend issues with flying insects- so 4 stars is the best I could give at this time

This product definitely lures flies into the bag; however, the substance used inside the bottom of the bag has a really nasty odor. Persons using this bag are warned not to get too close to the bag/odor or it may be harmful.

the bag says use outside because of odor, it is no joke it smells so bad. worse than a broken freezer full of meat sitting out all summer. guess thats y its overflowing with flies.
