Don't waste your money!
The mosquito cartridges worked so well in our Flowtron 80W that I decided to try the fly lure. $25.08 for ONE flimsy piece of 'stuff' to attach to the outside of the Flowtron. Not only did I NOT see any dead flies after attaching this item, we had a 20 mile wind with a slight rain one night about a week after putting it on the unit, the next morning this $25.08 flimsy piece of 'stuff' was broke in half and laying on the ground. Fool me once, shame on you, fool me twice, shame on me. This item will never be purchased from this house again! I hate being taken in with lousy material and design.

I don't know
It seems as though the light is really the main attraction. Nonetheless, I'll take any help I can get.

Complete waste!
With flys in overload and my traps catching tons, this lure attracted absolutely zero flys to my flowtron zapper..

Big disappointment

A whole lotta money for very little product
Don't let the size of the box fool you. Even though this item comes packaged in a good-sized box, this product is barely one inch by two inches. It's just a small piece of plastic with some type of pheromone embedded in it. Although it does seem to attract flies for a few days, it doesn't seem to last for very long at all. It's just a tiny piece of flimsy plastic! In my opinion, it's just not worth it.

Amazing!
On my porch in my backyard, there used to be tons of annoying insects flying around, because we live very near to a pond and we have woods. Ever since I got this terrific product, I have been bug free for almost 3 months now!I can go back to having bar-b-ques again! This is the most amazing product ever created!
