Ive hade this up for less than 3 days and there is at least 150 flies in there. Its insane. Had flies all around our porch and couldnt (and still cant ) figure out where theyre coming from. I put this up and on the directions it said wait 2-5 hours for the pack to dissolve but within an hour and half it was already attracting and had flies inside. It is now like a thick layer of dead flies and still its working like crazy. At night/early morning they arent around (i assume they go somewhere warm) and when it starts to warm up in the day theyre alllll around it. I really recommend this to anyone who has a fly problem outside. It does smell a bit so i wouldn't recommend it inside but its working better than i could have imagined.

from what I read on the reviews people were very happy with it so I decided to try it. I kid you not, this is truly amazing and it works 100%. I promise you you won't be disappointed. I like the fact that you touch nothing and even if you did it is not poisonous. It just stinks. you can't smell it while it's hanging as I have it right next to my patio but when you dump it out, take it far away because it is stinky. this particular one you would just throw away and replace it with another one. you won't be sorry if you buy this. You

I bought this last year and didn't have a chance to put it up. I put it up about a month ago about 20 feet from my outdoor patio and I am completely amazed at the job it's doing. I am going to buy these for every outdoor event I have. I will recommend these for any situation.

Never thought I would be writing a review for a fly trap, but this one REALLY WORKS! Run a string thru the top, pull the top up, add water and watch the flies die. Incredible!!! I'm throwing out all the sticky papers, and spray cans and other worthless stuff that I've spent money on before! Get this one, it's worth every penny!

These fly traps are amazing. We are seeing a lot of black flies right now, so we hung one up and it was nearly full in just a few days with more flies trying to get in. Whatever is in there, the flies want it badly. The traps put off a slightly offensive odor, but it works so well that I don't even care about the odor.

I can't say enough good things about these. I started using them early this year, and the fly population around our barn got knocked back to almost nothing. I took the traps down, and after a few weeks the flies started to be horrible again, so i started using them again. The first one was full in 3 days! The second one also filled up in under a week! Flies come from everywhere, just to die! They stink like death, but they are super effective, and better yet, SAFE. We don't use poisons, because years ago some flies ate poison then bit our dog on the nose, and it died. But these are safe, and I finally get my revenge on the flies that torment my horses and sneak into our office. I appreciate these so much that I looked for your website just to leave a review. We buy them at the feed store, but I wanted to say THANK YOU and tell everyone else too. Here's a picture of a trap that had been up 4 days. Ew! Yay!

The flies are horrible this year! I have tried every do-it-yourself fly trap you can think of and none worked. I saw this fly trap during a trip to Walmart and decided to give it a try. Within just a couple of days there were hundreds (literally) of flies in the trap. It does attract them so you do want to put the trap a bit in front of your porch (if that is what you are using it for). Definitely buying more of these!

I bought one of these outdoor fly traps after some kind of biting flies started attacking us on our front porch. It was super easy to activate: simply add water to the fill line and hang where flies are bothersome. By the very next morning, no more biting flies!! My mind was absolutely blown at how well this thing worked, especially considering it was so inexpensive. A few days later, there were hundreds of all different types of flies, gnats, bees, and even a butterfly landing on the bag and trying to get inside to the bait. I quickly shooed the butterfly on its way. The only con is that the bag starts to smell slightly of decaying flesh as more and more flies/insects are trapped inside. But I would rather have the slight odor than be bitten and overrun with flies. I cannot recommend this enough!!

The flies are horrible this year and couldn't find anything very helpful. I even tried a different style of this brand and it didn't work very well at all! This is the one! Thank you for this product! I have 3 of them set up around the yard and in one week, they were full! Awesome!

A relative mentioned these to me recently. I bought one thinking what could it hurt to try. In the past, I've had fly strips hanging outside but always found them to be unsightly. I live near a wooded area. In the summer months the flies are a constant nuisance, getting in through my old windows or when entering or exiting my apartment. I would spend most days indoors trying to kill them in threes time and again. No time after hanging the disposable fly trap outdoors, I noticed an immediate decrease in flies on my porch and around my windows. I was amazed to see how many flocked to the bag and was inside. I will have these on hand during the summer months every year. They are amazing.
