Does not work! Get the Rescue Fly Trap!

I have used several different brands and kinds of fly traps like these, always with great results. I thought I'd give this design a try. I hung it very near another brand (Pop Up) and the other bottle got filled with flies, while this one only attracted about a dozen all season. I also found it harder to handle. I spilled some of the nasty water on myself while flipping it to hang it.

Did they change the formula? I been buying these every year to hang in my dog kennels to catch the flys and they have worked amazing in the past, they been up for almost a week and have 3 flys in them but I can see hundreds all over the ground, gonna have to find something different

I've used the Trap & Toss by Starbar for many years. As soon as the fly attractant is put in the water, flies congregate & get caught. I hung 4 traps in various locations on 5/21/24, in the horse barn & after 20 hours, almost a full day, there are no flies in the traps, but an abundance of flies still active. I clean up the barn 3 times a day, so there is no manure there very long. I feed Simpli-fly, which is a feed through fly deterrant & I release fly parasites once a month. So I'm very diligent in managing flies. I believe the product sold must be old stock & that it is now ineffective. Obviously, I can't return them, but would like to have my money refunded.
