Not helpful for fruit flies
Was not any more effective than apple cider vinegar. Definitely not worth the price!

Bad insect trap
Very ineffective in catching flying insects. It's much better to use the electric zapper instead of this fan trap.

This thing is a beast!
[This review was collected as part of a promotion.] This trap is a beast!!! It performed more than I expected it to, and it covered an entire living room with just one of these traps. The design of it is sleek, almost like it’s part of the decor and it didn’t weigh as much as I thought.

It’s an okay product
[This review was collected as part of a promotion.] This product is not that bad . It works when attracting some bugs but it is a little harder to actually get them to go inside and stick to the sticky trap. Works great for moths but have to use bait for the fruit flies but overall the product is not that bad .

Great for gnats and mosquitoes!
We used this trap one night in our kitchen and caught many gnats and a mosquito. Fast forward 8 days and the sticky board is full of bugs! Trap includes extra sticky boards. No chemicals, can't hear it running, small, lightweight unit.

No need for a fly swat
[This review was collected as part of a promotion.] The Flying insect Fan Trap is about the size of an essential oil diffuser. It’s very light weight and sounds slightly softer than a portable air purifying system. It has three time limits 3,8, and 12 which are typically great for summer events or just keeping your door and windows open all day. It did manage to snag a few flies, but it for sure caught other flying insects. I would say it’s safe enough to leave around children and pets. It’s perfect on a back patio and saves you time, money, and energy swatting all day.

Doesn't work on Flies
This worked for gnats, but I originally bought it for flies. I have had this for a few months, and it has never, not once caught a fly. I have moved it multiple times and has done nothing for the flies in my house.

Thank you for letting us know, Jolene. We'd expect the pairing of UV-light and a fan to quickly take care of pesky flying insects. For best results, use this in dark spaces or at night. That said, we'd appreciate the chance to make this right as your experience wasn't as expected. So we can, reach our experts at 877-869-7546 (weekdays between 8 a.m. and 5 p.m. CT) and mention your reference number: 23000441. We hope to hear from you! – Brooklyn, STEM Consumer Care

Highly recommend, especially if you have pets
Incredibly easy to use and get going, and it has been our most effective solution to date for dealing with the occasional bout of drain flies. We've tried the pheromone traps and vinegar traps to mediocre success, but this electric fan has been a game-changer to the point that we're grabbing a second so we can divide and conquer the pests. For every 1 that the traditional traps catch, this thing snagged 3-4. No weird smells, no sprays, no mess if it's knocked over by a cat, it's a quiet fan and low light that I was not expecting to be so effective.

This does not work
This does not work at all. Just moved so a lot of flies go through the door. So I bought this and in 3 days not one fly has landed in it. One tiny little gnat is on the sticky trap and that’s it. Not worth $30

Works great! I leave my back door open from time to time for my son and my cats to play in the backyard. This has helped so much with the pests that come in.

Poor product. engineers need to reverse engineer this item.
bought this to get rid of my gnats issue. I saw some comments about not getting the bugs. it's true, the air pushes out, instead of pulling in. The gnats just danced around the opening, and I feel like the only way the gnats died was due to them going inside and getting hit with the fan and landing on the sticky stuff. I tried honey soap and water and this works better to get the gnats. I decided to get a light zapper for the bugs instead of this thing. would not recommend this product.

Thank you for sharing your experience with us. We're sorry to hear the unit didn't function as expected. The fan should work to pull insects in as the UV-light attracts them.
