Catchmaster Fly Traps Outdoor 3-Pack with Airlock Lid for No-Mess Disposal, Pesticide-Free Hanging Fly Jars, Reusable Bug Catchers for Yard, Patio & Trash, Sets Up in Seconds

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!

Works great at catching flies in my garage. Not sure if it attracts or kills what is already around. Smell is terrible but it does its job.

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.

Well, 2 ways to look at this! First off, it really worked! It was gross to see the hundreds of flies that it caught w/in a couple days! But it says to keep it out side and I'll tell you why! I spend time out in our garage and originally placed it right outside the garage door. It started smelling like hot, rotten garbage so I just assumed that it was our actual garbage since it was summer and that can happen. I finally realized it was the fly catcher. OMG, I can't even describe the horrible smell, BUT it worked and I guess that's what flies like! So, basically if you can deal w/ the smell it does work!
