Catchmaster Disposable Outdoor Fly Trap, 8 Hanging Bags with Bait | Catches house, bottle & blowflies, Holds up to 30,000 flies, Food-based lure, no spray needed, For barns, coops & ranches

These were much better to set up than the last brand I bought; they included ties which was unexpected and very nice. I just put them up this morning so TBD on how effective they are. Using them to attract flies away from our chicken coop and I did go out a few hours after putting them up and there were fewer flies around but could also be because it is starting to get warm. I feel the flies are the worst during the mornings and evenings. TBD I'll plan to update this review after seeing how they work. The bait does stink though so should be good.

These fly bags are great! Work great just don’t put to close to your doors or windows do to the smell of the fly bait

The rescue traps have gotten so expensive I wanted to try another brand. I like the size of these and the screw up b/off lid for easier disposal but other than that they’ve been a bust. The attached photo is after a month of being out in the same spot we always place one. The rescue traps would be overflowing after two weeks and this one has barely caught anything. The attractant used is completely ineffective. Don’t waste your money on these if you have a lot of flies in your area.

We are rural but don't really get flies and enjoy our property all through the year - until it starts to turn cold in the fall. Then the filth flies come in droves to our property from seemingly miles around. The air stays still and warm under our patio cover and the flies roost under there in the hopes of not yet freezing to death as they inevitably will. Meanwhile I put these bait bags out in the hopes of reducing the number of flies trying to get into the house from the patio. These bags start catching in a day or two and are quickly stuffed full of dead flies so I go through quite a lot of them. These bags do help a lot but I also think they're a catch-22 - if I put them under the patio roof where they will do the most good, they also seem to attract more flies to that area. If the flies weren't more strongly attracted to the warmth under the patio roof than the bait, I would definitely locate the bags further away from the house. Next year I'm going to try releasing fly predators to see if I can reduce the population. I have a feeling they are flying in and not breeding in my area, but we'll see.

This work about 90% of the time. But after being up for a few days it stinks so bad.

It does a great job of attracting the flies and disposal is easy too. Open the bag, fill with water up to the line, hang and let it go. When it's full just close turn the cap and toss it away. What you can also do is use an ice pick, puncture a small hole at the bottom to allow any water to drain out. However, the smell is horrendous. I wish they could figure out a way to reduce the smell but it's one of the reason flies are attracted to it. In Hawaii, flies are a year round problem but more so in Summer than any other time of year. I find myself changing bags out at least every two weeks if not sooner.

I removed another brand’s fly trap the same day I installed this catch master. Second day I don’t smell an odor and there are only a couple of flies in the water. Compared to the other brand which was swarming with flies. I’ll give it a couple more days but so far I think I’m losing time in catching flies I waited a few days in the catch master does have an odor which is strong enough to draw flies it took days for that to happen and maybe the dying flies inside the bag made the smell worse. But the other brand collected more flies faster in the same period of time

I have about 12 of these hanging around our farm, near my cattle, near my chicken coop, our rabbit runs and our duck pens. They work and are quickly filling up with flies. The ones that hang in the sun, and hang close to the ground seem to be the ones with the most activity although even the ones hung in the shade up in the trees have a lot of activity. I would highly recommend these for getting rid of flies. One thing to think about, the earlier in the spring these are hung, the better you control your fly population although it’s never too late to hang these. I have three bags that have completely filled up in a little over a month. Another thing to think about is to not let them dry out, they need water to keep attracting the flies. They are gross but they work well and am thankful to have them. 100% would recommend them! Edited to add- these used to be my go to, but for the last two years, the bags have broken so easily. Just got an order of four, hung them and the very next day all bags were broken so it seems like they changed the plastic bag to a lesser quality? I’d change my review to a 1 star if possible.
