Katchy Duo – Indoor Fly Trap with Scent Pod – Day & Night Effective – Mosquito, Fruit Fly, Gnat & Small Moth Killer – Non-Zapper Trap with UV Bug Light & Fan Suction (White)

7 days later update: flies are nearly gone in the house! We think we found the source in my son’s room so I’m sure that had a lot to do with it, but catching fewer every day and hardly any flying around. Been running on auto mode only last 3 days. The Duo came with 4 traps which I was changing daily until the last one I left until today. Their replacements said product size 4.3 inches on the listing so those the replacements I bought, but they are too big. IMO their replacement glue traps are too expensive - looks like they are actually 3.4”. I just cut down the larger ones since I already had one, and I also have the yellow butterfly shaped ones for houseplants I saw others use before I get more. I did try without soap in the bait cup and noticed specks of wine on the top of the bait cup - wondering if that’s from little fly feet dipping in and landing when it’s off so I went back to using soap. Does work slightly better putting the bait cup on after filling and then putting on the lid but it spins a little. You have to really press and twist to get it on but the sides are high enough that it seems hard to spill anyway. Overall still very happy with the purchase and glad we got in white to stay out in our kitchen. Original: Overall, I’m satisfied with this purchase. I was skeptical of some of the others I looked at - one was more expensive and had a ton of reviews that were all 5 stars so I was skeptical and skipped that one. Others didn’t have the bait cup, auto mode, and/or only came in black. I also wanted one with a more universal size and shape for the sticky traps so I wasn’t limited to more expensive replacements. We are dealing with fruit flies that probably came in with the garden vegetables over the summer and recently multiplied with kids leaving dishes and cans in their bedrooms. We started about 5 days ago putting bowls out with apple cider vinegar and some dawn dish soap. They were definitely attracted to them, but there was a disappointing number of fruit flies around the edges of the bowls and on the cabinets and lamps nearby instead of in the liquid. Dumping them out the next morning we got more than I expected, but seeing some around the edges creeped me out so I got this and it came the next day. I like that this one has the bait cup so you have more than just the light to attract them. Others I looked at said to put a capful of vinegar next to the device to attract them but I question how it would trap them if it’s on the counter at base level when the fan and suction are at the top. This arrived in the middle of the day so I immediately filled the bait cup with some old Christmas wine and dawn dish soap (not sure it has to be dawn, that’s just what we had). By 5pm there was a satisfying number of fruit flies on the sticky trap. We turned off the lights and put it in auto mode in the kitchen overnight - I don’t think we got many more than we had already. I changed the trap and by the afternoon it was about as full as the day prior. Not like I counted them so there may have been more, but makes me think that even though the trap wasn’t full, there’s a limit to either the effectiveness of the sticky trap or the bait. I refreshed both today. We’ve used this product for 2 nights now and the fruit flies are noticeably and significantly reduced. While I doubt that this device is solely responsible, I think it’s better than watching them on the edges of the bowls and not going in. It was satisfying to see one of the edge of the light I went to squish and when it tried to take off it got sucked into the fan. It’s not 100% perfect but still giving 5 stars because I feel it’s better than the comparable options I was looking at. Most are black and I wanted white for our kitchen - I have a garden and plants and we plan to leave this on auto mode to use nightly on a regular basis. I also chose it for the bait cup - seeing how crazy they went for the apple cider vinegar and wine we tried in the bowls we wanted to keep using that. It came with only a handful of traps and this brand’s replacements appear to be expensive. They say they last long but I’m changing daily right now while we are dealing with the problem. As there gets to be fewer caught, I can see going longer between but probably not months. I bought another brand’s 4.3 round traps - there are a lot of inexpensive options. I haven’t used yet but appear they will work. There was another device like the katchy I looked at that had a triangular base and I didn’t see as many options for replacements so I avoided that one. I wish the lip to pull out the sticky trap tray was a little taller - it’s low to the counter so you have to tip the device back a bit to get under it and pull it out - makes me worried I’ll spill the bait cup that sits on top but haven’t yet, just have to be careful not to tip too much. When pulling out the sticky trap, some fruit flies flew out of the base so they aren’t getting 100% driven into the trap and stuck. When I turn on the Kitchen lights in the morning, I am switching it to manual mode to keep the fan going while we deal with the problem. While I think it only catches a little bit more than the bowls we were using, we aren’t seeing the significant number of flies nearby hanging out. That could be just because the numbers are being reduced after several days of working at this, but it’s nice to see. The fan definitely sucks them down when they get close so there aren’t many nearby. I had read one review that the bait cup is a little difficult to open and close, and I agree. There are three little internal tabs. You have to press on the lid and sort of twist to get it to stay. The bait cup itself is small - it says to only put a tablespoon of liquid in there. What’s nice is that the lid has holes, so nothing is getting in the cup. The dish soap created a bubble on top when I took off the lid - my understanding, the dish soap is to break the surface tension on the liquid so the bugs can’t get out. Not sure what the point is of using the soap if the holes are so small the bugs can’t get in so I may stop using the soap. Yesterday I left the bait cup on the device and just removed the lid to top off the wine in and I spilled a couple drops on the fan. Didn’t seem to be a huge deal so I just left it but there’s always a worry about liquids and electronics. This morning I took the bait cup off to dump and rinse and then refilled on the counter. The best way to get the lid on and off is to pick it up and hold the cup in one hand and the lid and the other and twist together, but you don’t want to do that when it’s full. Because the bait cup is tapered and not very tall, and the edge of the lid is very short, it’s harder to get a grip to hold the cup still so you can put the required pressure on the lid to twist it. When we first got this, it seemed like you had to rock the bait cup to get it seated, but now it’s more of a firm press straight down. I think I’ll take it off to rinse and fill it, and then put the bait cup back on the device so it’s holding the cup in place while i put on the lid. The wine I’m using is red and it doesn’t appear to be staining the white plastic, even where I spilled it. Even if it does, it’s not seen from the outside. Auto mode works very well - comes on instantly with low light. I like that you can adjust both the fan and light levels. I don’t think this device will solve the problem by itself, but any pest probably you have to attack with multiple approaches. We made the kids deep clean their rooms, put sticky traps in the house plants (although they don’t seem to be around them), and we aren’t leaving fruit on the counter right now. Hasn’t been a week yet but the numbers are going down each day and hopefully the issue won’t be noticeable in a few more days. We will probably keep using this on auto mode in the kitchen nightly as preventive maintenance - it’s also supposed to work on mosquitos which we get in the kitchen as it’s right near our main entrance and has 2 other doors to outside we use in the summer.

I bought three Catchy Duo fly traps and I’m really glad I did. I originally started with just one, but after learning how fruit flies behave, it became clear that one trap usually won’t wipe out an entire problem—especially if the flies are spread across multiple areas. Once I added two more and placed them in strategic spots, the difference was immediate. Setup is simple, and the traps have been very effective for me at catching fruit flies/gnats. I’ve seen other customers say they’ve caught tons of flies (someone mentioned over 100), and based on what I’ve seen in my own home, I believe it. A big key is using the right bait and keeping it fresh. Replacement sticky pads aren’t expensive, and as long as you refresh the bait and place the traps in optimized locations (kitchen, near fruit, trash, or wherever you’re seeing activity), these traps can help you eliminate a fruit fly problem quickly—just like they did for me. A couple quick tips based on what I’ve seen others mention: double-check your package contents for the sticky pads, and if your unit ever seems to stop working after a day or two, it’s worth testing a different outlet/location right away. Overall, when set up correctly, this has been a fantastic solution and I’d absolutely buy it again.

I had this Katchy on for 2 weeks. I put in the Apple Cider Vinegar and a drop of dish liquid in the top. I slept with it on. A mosquito the other night ate up my arm. The katchy sticky pad for 2 weeks is clean. Spotless. Not one bug. I am not sure if I received a defective item or not. It did not catch any bugs.

I love how easy it is to use, the quality of the product is good but I would say the design with the pod on top isn't the greatest idea... The pod on top can leak very easily if you go to pick up the device. Then... the designed it with the circuit board on the inside, literally BARE BONED little circuit. So, if the fluid spills, especially while the motor is running and fan is spinning, it splatters the vinega/soap mixture right onto the little circuit board. As far as everything else goes, I love the size. I thought it was going to be taller but it's nice and compact. The sticky pad has caught eight bugs ranging from a larger gnat/fly hybrid looking creature, to the tiniest gnat imaginable ! We've moved it around the house to see where it works best and we don't really have a solid answer. It caught a few in our kitchen and a few where I grow my seedlings and plant trimmings by our back window. We turned off every light in the house and only left the Katchy light on and it didn't make a huge difference, so it works with or without, which is great! The sticky pad comes out easily with some tweezers, and the sliding tray just pops out of the bottom. Power is good, noise level is damn near dead silent. Cord is long enough to set it on a counter top, however, again, where I have mine placed by my back window, it needs about an extra 2 ft of extension cord. No biggie. I love that I don't have to hang a sticky trap that winds up getting caught in someone's hair or on the walls and ruins them. This is a much more effective and clean alternative!!! Again, get the old Gen without the pod on top. That's why I gave it 4/5 stars... I just think the circuit board inside needs a thin cover.

So I literally only received this less than 15 hours ago and had to report back asap because of the results. It does *exactly* what's advertised. I was pretty skeptical after reading many recent reviews but decided to give it a try anyway and didn't expect much out of the Katchy initially as a result. As soon as I turned this thing on though, 4-5 tiny gnats got sucked in and trapped on the sticky pad instantly. Before the use of vinegar as bait. I have indoor plants, I don't overwater them, but I did have to leave for a long trip which required that I seal my plants in clear bags. Huge gnat population explosion inside said bags (goes to show that dirt is never insect free), so naturally I've done everything people do to take care of flies. Can't put my plants outside due to weather and naturally take care of the issue that way, so this is the next best thing I can do on top of being extremely cleanly and making sure no sources of water/food exist for these guys to reproduce in. I've situated the Katchy right by my plants, and made sure it stayed on all night via the manual button on its face. Safe to say that, currently, I'm really happy with my purchase. I'll update and fully review when I've used up all the sticky pads! //UPDATED PORTION// APRIL 16 // So I've used up all my sticky pads over a week and a half ago, and I have to say this thing does what it's supposed to. It'll suck in all the gnats. It's not enough to destroy an entire gnat population, as you'll need to systematically get rid of or quarantine anything they can infest before that happens, but it does help make your living spaces visibly pest free. After the sticky pads got all used up, I've resorted to applying a mixture of honey and water to the bait tray as a more DIY option and that works just as well as the pads. I've also purchased another Katchy, so both sides of the house get serviced, and this on top of all my other traps are working really well together. Conclusion? Understand that it's not going to end your pest issue for you, that takes some real work and thorough cleaning which can take weeks or even months, but the Katchy does make your issue far less annoying of a problem in the meantime and is very easy to use. I appreciate that this product exists as traditional DIY methods aren't as effective or easy to clean, and I'll give the Katchy a mention to my friends and coworkers because of that. Thanks!

I have over 100 potted houseplants all over my house so in the summer I usually have a horrible gnat problem. I usually add a soil amendment to control them but that gets expensive and time consuming so thought I’d try the Katchy. I purchased two, one for the living room and one for the kitchen. At the same time I purchased two passive gnat catchers Zevo and Safer, they have a light, a sticky board and plug in but no fan motor or moving parts. The Katchys are operational only at night so run about 12 hours each 24 hour period. The plug in Zevo and Safer lights are always on. One Katchy I put the vinegar in and the other I ran without it. It’s been a year for all four to be in operation and one Katchy broke after six months and the other is still working. I took the broken one apart and found the vinegar just made a sticky mess and no difference in the amount of gnats caught. I cleaned it and found it was still not working well so threw it away. I found the Katchy to be a very expensive gnat trap with poor longevity and the passive gnat catchers like Zevo and Safer to be less messy, lower maintenance and catch about the same amount of gnats with less work and for less money. The addition of vinegar made no significant difference when comparing the two Katchys running one with and one without for the six months before the one stopped working. Also, the Katchys are fairly noisy.

I wasn’t sure this would make much of a difference, but it surprised me. Within the first couple of days, it had already caught several gnats and tiny flies that had been driving me crazy. I like that it works quietly and doesn’t rely on harsh chemicals, so I can leave it running without thinking about it. The scent pod seems to help attract bugs, and it’s much nicer than constantly swatting flies around the house.

Worked fine for about 6 months. After that i started noticing few and few bugs getting pulled in and or sticking and yes that is with changing the stick taps every month or so. The UV light goes really dim after 6 months as well. I would still see gnats flying around. At this point it crapped all the way out the other day where the fan won't move and the light barely comes on. At this point id say spend more money and get something else. no Tech support when i reached out! All right well today as of October 19, 2025 I received two new replacements on Amazon that I had purchased both of them right out of the box had issues with their light rings lighting up all the way around so they’ll be returned today. I think the technology with this company has went downhill and they’re not doing proper QC testing before they sent out a product or Amazon is dropping them on the ground and they’re breaking before they get to me one of those two.

This thing is great. It caught about 30 fruit flies in a few days when I had an infestation. Worth the money for sure. I don't have to worry about the aesthetics of the sticky traps or them accidentally touching me or my other things when they're covered with dead flies. I love that there was a white option, even though it was a lot more expensive than the black one, and I like that it has a purpleish light instead of blue.

Le principe de l'appareil est d'attirer les incestes par sa lumière et l'appât que l'on place dans la petite capsule prévue. La bonne nouvelle c'est que la viande avariée et la grenadine qu'on place dedans ne sent pas quand elle pourri : c'est dû je pense au ventilateur qui aspire l'air (à vérifier). Photo des incestes capturés Ce qui est OK c'est que les insectes sont attirés, sauf que les mouches s'échappent sans problème, l'aspirateur n'est franchement pas assez fort. En mettant "tout à fond", c'est un peu plus efficace, mais ça reste juste. Mais là ça devient franchement bruyant (voir la vidéo)
