Catchmaster Reusable Outdoor Fly Trap, 2 Hanging Blue Jars with Bait | Catches house, bottle & blowflies, Food-based lure, low odor, Buy once, just add a refill, Covers your whole yard & patio

These are amazing. I shared 1 picture with the label removed so you can see how many flies it has captured over a 3 week time span. This fly trap is not far away from the back patio. I have 2 fly traps on that tree. The second picture is out by our live stock pens. Its not as easy to see, but it also highly effective. I will warn you they do have an unpleasant smell - which is why they work so well !!!!! When I change these out I pour the contents of the catch into a plastic grocery bag and then put the grocery bag into another grocer bag, then into a garbage bag and then into the garbage to prevent the smell from spreading. The amount of flies caught is so gross!! That's what I paid for. I do live in a very dry desert environment and I do add water through out the weeks as the water evaporates so fast. Easy to do.

Excellent item, we've been ordering them a lot. Our neighborhood has a lot of new homes being built and naturally the workers leave food and trash all over the jobsites and the flies just keep coming from all directions. Simple setup, super cheap and works great. Just add water, swish around to mix and dilute the pouch and go hang on a tree somewhat away from any open windows and sitting areas. Mine is about 20 feet away from our patio, and on the wrong gust of wind and a hot day you can catch a nice gust of horse and other animal manure which is what attracts all the flies. Works great though and highly recommend it, just don't use indoors lol!

OK, this fly trap attracts flies and kills them, a ton of them. But as long as you have it up and going there will continue to be flies because they are attracted to this fly trap. The flies will keep coming. The smell is hard to tolerate. We had it going for 5 days and a ton of flies were trapped and killed which is SUPER GREAT! The smell is really strong and offensive, even to the neighbors if they are close by. So it kills tons of flies and has a sickening smell. We have vultures in the area too and they could be attracted to the fly trap as well.

I have a small farm with 3 horses. I bought these because I was using a Captivator trap and it was working really well, but I needed a few more. These were a few dollars cheaper each. Here is what I found: The pros: They work well to catch flies. Decent price The blue jars means you don't have to stare at dead flies as much The top that lets flies in can be "locked" open or closed The cons: They are much smaller than the Captivator traps so they need to be refilled more frequently Jars are flimsy Caps do not screw on well (but they did seem to hold, even if a little off-kilter) Blue labels makes it harder to see when the trap is full or needs to be re-filled. Stinky is an understatement- but this is true off all traps of this type, and what makes it work. Pro-tip- WEAR DISPOSABLE GLOVES when you handle these. These traps worked pretty well and did catch a lot of flies, but they did not hold NEARLY as many as the Captivator traps that are just about $2 more each. Also, the small size and amount of water means these traps dried out quickly this year and the bait had to be refilled more often.

Worked great last summer, about to order refills for it.

The scent of this product is the worst. I had good results with another brand and wanted to continue my killing of flies. Tried a cheaper brand "Catchmaster." Simple instructions, easy to use, horrific scent to attract flies. Filled to the appropriate level and suspended in a corner, away from the potential of smelling this with even the slightest breeze. The bad part was that the portion that supports the weight of this system broke loose and spilled its vagrant contents into my yard. One of my dogs didn't refuse the putrid odor and lapped it up (non toxic,) well some of it. The rest looked like a wet spot of dirt. Word spreads fast. Within a period of 3 hours (from when my wife notified me at work about the catastrophe that happened,) to the time I got home, I could understand why she vomited on the patio. The ground was solid black with flies. Any disturbance would send them into a frenzy. Looked like a scene from The Mummy when the plague took over the desert. There was nothing I could do to stop their draw to this milky, disgusting fluid. I had to endure the flies trying to penetrate my visible orifices, until I could collect the rancid moisture that collected in the soil. Shoveled this failed option for collecting flies into a bucket and tried my best to figure what to do next. Any ideas? How much does it cost to return to the manufacture to figure a solution, so this doesn't happen to anyone else?

Wow this stuff really works and works fast, very simple to use. We have orchards, chickens and cattle so flies can get quite annoying in the summer months. I put 2 of these out and in an hour there were a lot of flies in both. After 2 days both were loaded. But it needs to be away from areas where you relax or kids and pets around. IT REALLY STINKS!!! You do not want to get that liquid on anything, especially your kids or a curious pet. My only dislike about it is the cap. When you open it up it slides down into the closed position unless you hang it up. Also if your yard is small with limited air circulation the smell might be overwhelming.

** I would like to add that while they are technically reusable I would recommend NOT reusing them after a certain time. I emptied one from last season and refilled it. The jar is working perfectly fine, and continues to catch flies. However the dead fly detritus that I emptied into a plastic bag and then tossed in my trash can has become a swarm of fly larvae. Hundreds of little worms hatched with in a day of rustling up and disturbing the trap. So either learn from my mistake and if you intend to reuse the jar, empty it and refill promptly. ** This thing is great and disgusting at the same time. We live downtown and have dogs so we get a ton of flies in our yard, and this this is great. I got this jar one and the bait replacements and the jar gets filled up with flies in a month. The smell is awful... something between dog poo and death, but the flies go straight to it. To change the bait I put on disposable plastic gloves and dump the contents into a plastic ziplock bag and zip it up and throw it away on garbage day, gloves and all. I also keep it in the furthest corner of my yard which keeps the smell from being intrusive.
