Katchy Duo – Indoor Flying Insect Trap with Scent Pod – Day & Night Effective – Mosquito, Fruit Fly, Gnat & Small Moth Catcher – Non-Zapper Trap with Blue UV Light & Fan Suction (Black)

This review is specifically for the Katchy Duo 2 in 1 (because Amazon combines reviews for similar products but you need to know for an exact one.) For the last few years since I had moved into my apartment. Every summer (It can get over 90F and 100F here) specifically about a couple weeks into summer and carries on until it starts getting cold outside in the fall and the insects die out because of the cold. I get these annoying little Fungus Gnats, or as I call them the drunken idiot of the Gnat species since they can't seem to fly a straight line and randomly bump into everything. But they especially love to hit you in the mouth and eyes. They are worse right after a rain. I think they are coming in through small cracks under the door as I think the pine tree needles around my apart are part of the reason they are so bad here since I do not have any plants in my apartment. I deliberated for a couple of summers about buying something like this because $50 is not cheap. The first couple of summers I tried every home remedy trick I could find. From apple cider in a jar with plastic wrap, to sticky fly catchers hanging in several places one in the room with me. I even tried spraying bug killer around my apartment entrances. All of this to no avail. Nothing seemed to work. These tiny pests make you want to rage as they constantly hit your eyes and land in your drink (I literally had to stop using a cup to drink from and had to start using a sealed container.) I was always getting angry as they hit me in the face every few minutes. So this summer just a couple weeks ago as it started. I decided it's time to give this a try. I had very little expectation this would actually work for Fungus Gnats as there aren't very many people mentioning their effectiveness. And it's the only bug that seems to get into my apartment aside from the occasional fly and spider. I thought, well this is likely a waste of money but nothing else seems to work. Wow, was I wrong. It is incredibly rare that will buy something I think is expensive and assume it won't work all that well. Only to be so incredibly happy with how well it works. While yes it does not catch every single gnat right away as new ones find their way into my apartment. They don't fly around long before making their way into this bug catcher. As for how loud it is. I would say on the lowest setting it is quite than my gaming PC fan. In a totally quiet room with nothing else running you can hear it. But it's quite enough that it is easy to ignore. On the highest setting, it's only slightly louder. But still, nowhere near that of a PC fan under load. I was leaving it on automatic setting so that it was only on at night and when I am not home (blackout curtains in the room it's in). But on my days off I set it to manual and leave it on. In the picture, I am adding. You can see the sticky trap on the first night, one week later, and 2 weeks later. To think all of those gnats would be constantly hitting you in the face if they were left to fly around in your home. After using it for 2 weeks now. I can not overstate how well I like this product and how well it works. It is definitely worth the money if you have an issue with Fungus Gnats every year like I do. As for how long this product will last or how long it takes for the fan bearing to wear and become louder. Only time will tell. If you are like me and are looking for something to help get rid of these pesky rage-inducing nuisances but were having trouble finding a review that explains how well it works for this pest. Then look no further as I hope my review helps you. And no, I am not a paid reviewer, nor was I given this. I try to be frugal which is why it took so long for me to risk spending money on something like this.

Look at the many photos of how many flies and gnats are attached the sticky boards. I have two. First bought, the shorted out by water getting on the PCB board attached vertically on the side. maybe it was also the flies. Taken apart and with multimeter tried to troubleshoot and could not get it two work. So I bought a second one and kept is away from the kitchen (not happy but did not want to short it out, too. After second purchase and running awhile, I was determined to continue to try to fix the first. at least figure out the circuits and create a schematic. This time I managed to get it to work. only the fan would not adjust speed and worked only an manual. That's OK for me. I cleaned the board with 99% iso alcohol, and covered the PCB with Kapton tape and put it back into service. The one in the kitchen did not do very well katchy the flies, so I created a kind of DIY vortex with aluminum foil, see photos. It increase the brightness reflecting on the foil and works great! With the Kapton tape, I no longer have an issue shorting out the PCB board The second I repeatedly kept knocking off onto the floor and the upper light ring brok. It would not snap back on. Looking at the photo, I glued it back on with some heavy duty glue and taped it firmly secure until the glue dried. Now the sticky boards fill up with flies, the black one despite having an air scrubber directly above the Katchy. So the negative issues: 1. get water inside you may short out the PBD board. Solution DIY fix 2. In some instances the flies will fly right over and not get sucked in. Solution create a DIY vortex above the Katchy 3. Repeated dropping may pop the upper part of the light ring and will not snap back on. Solution glue back on with clamps, (or tape.) 4. Block the outer edges of the liguid cup, or the vinegar being acidic will get drawn down fast and get onto the PCB board. Solution tape or cover the outer holes. 5. don't try to save money and make your own DIY honey sticky board. in my case it just did not work and extra sticky boards are inexpensive. Both mine have been running no-stop for over a year and they catch fruit flies, gnats and even the house flies. I am happy with them, however you may have to do some DIY modifications, (Aluminum vortex and covering the outer edges of the liquids cup if using vinegar. And if fails or breaks some DIY skills will put them back into service

I was having a terrible time with fruit flies, gnats, and drain flies. I tried some of the various fruit fly traps and baits but they really did not do very much to reduce the problem. I was looking around and discovered the Katchy Duo 2-in-1 Insect Trap and decided to give it a try. I am so glad I did because it really works! It is very simple to set up and use EXCEPT for filling the liquid bait capsule on top. The instruction booklet just directs that it be filled with a tablespoon of apple cider vinegar and a drop of dish soap. The problem arises in trying to open the capsule and it is even worse to close the top and lock it in place (I am a senior citizen so my eyesight and hand strength are as good as they once were). To open the capsule, the top needs to be rotated about 3/8ths of an inch counter clockwise. To put the cap back on, it is very hard to see how position the top so it will go back on the capsule enabling it to be locked in place. After much frustration and spilled vinegar, I finally noticed there were tiny protrusions on the side of the top and on the side of the base of the capsule. They were very hard to see as I did not know to look for them. Once I found them, I marked them with a silver permanent marker that makes them easy to find and use. As can be seen in the photos (sorry for the poor quality), when taking the top off, hold the base steady and gently twist the top counter clockwise 3/8ths of an inch and then lift the top off. To put it back on, line up the marks and rotate the top clockwise 3/8ths of an inch. It is recommended to use the Katchy Duo in automatic mode. This will turn the Katchy on when the room is dark (this is the most effective time to attract and capture the files). The device is not designed to run 24 hours per day. If you do that, the units lifespan would be significantly reduced. The device works by attracting the flies (with the apple cider vinegar) and when the flies arrive, they are sucked in and blown down to the bottom of the Katchy where they are trapped by very sticky board. When the sticky board is full, simply replace it. I use the highest setting for both the light and the fan. For best results, the bait capsule should be refilled with apple cider vinegar and a drop of dish soap es needed. I have found that it needs to be rinsed and recharged every three days. The device will work if you do not refill it regularly but it will not be any where near as effective.

So, I don't review much at all. But I felt I had to say something about this Katchy Duo Indoor trap. I've purchased previous similar products and felt it was a waste of money. However, this works really well. I bought this because I was getting tired of gnats floating in my beer and just overall flying around. I live in AZ and the Phx area. You would think we wouldn't have this problem, but I have a lot of citrus and it does occasionally get humid here. With that context, I can say yes, we get the bugs of the flying variety :). We keep our house clean and free of standing water, so we are perplexed as to why we have so many annoying gnats, flies and moths. Well, it's because in the winter, we mostly keep our windows and house open. Screen doors and windows only do so much before you get flying pests. So even though I've had poor experiences with similar products, I felt the need to try something. I'm really glad I landed on this Katchy Duo. You get a two-pronged approach with the light and the liquid scent pod. I just set mine to auto and it adjusts the light and fan to the appropriate conditions so you're not wasting resources. When I first got it, it says to use apple cider vinegar, but I didn't have any. So, I knew they liked my beer, so I looked it up, and if you don't have that use an IPA or stout beer instead. I eventually got the apple cider vinegar, but I could not find any difference in results. This two-pronged approach really does work. I like this so much I purchased another one for better coverage. Yes, it's a tad pricey, but I think it's worth it. I attached a pic which I was still amazed that it did so well, but prior to this there were larger bugs such as moths and house flies. I will say it takes house flies longer to figure it out, but eventually I got the one that was really annoying.

This is a device that I believe is good for a large home with a insect problem. I live in an apartment and katchy works as advertised. I just didn't know that the over light would be so bright, and the noise fan. Yet, I was going to keep it but because my cat is highly sensitive with behavioral issues and the uv light even on the lowest setting dissuaded her from being on the kitchen counter, and even on low uv light it was uncomfortable to my eyes. Yet the 3 whammy effect of the uv light, scent pod and the sticky pad I believe is the best solution and the katchy device is worth the price. This is why I say it should be purchased by a person and or pet not so sensitive if in a 1 or 2 bedroom apartment. For a home this is much more ideal even if the noise & uv light is bothersome, because it can be put in an area where there is less people and pet traffic. This is why I only give the katchy device three stars, and I will be returning it.

Even in Southern California with leaving the bedroom completely sealed all day and night we would still wake up covered in bites. Or be unable to sleep due to the buzz of mosquitos. With the lowest fan and light setting we were able to catch almost 30 of the little bloodsuckers in just under two weeks. After that it stays on auto(turning on at night only) and we may catch one every two weeks. Completely wiped out our mosquitos in the bedroom problem. Also caught some fruit flies, an aphid(plants in the room), a few moths of various types and the one random beetle. The cap for the scent trap as one reviewer on youtube put it is not difficult to operate. It's not a snap on, it's a twist lock and has indicators molded on the side. It's very easy once you realize that. We use a cotton ball on the inside to prevent spills. The noise of the fan isn't too bad as we usually have a fan, humidifier and or AC unit on. The UV light is a mixed bag. On the one hand you can't see through your eyelids when you try to go to sleep, and it's a nice night light to get out of bed for the occasional midnight bathroom break or snack( where my snack people at?). On the other hand, even on the lowest setting it will light up the room and anything UV reactive, especially if you have white sheets or blankets. Which on our personal annoyance scale is maybe a 3 out of 10(10 being unbearably annoying). Even though I consider myself very light sensitive especially when it comes to bed time, so much so that I tape all LEDs, I don't mind the black light. Red or deep amber/orange lights are ok but anything leaning towards blue or white is a no go for me. We can sleep through the 70s lightshow just fine. Bottom line. If you have a home mosquito problem and have tried everything to stop the biting, try this. I've hiked through the Sierra Navada Mountains in peak mosquito season twice and lived in the south so I understand mosquitos and I HAAAAAAATE mosquitos. But they love me. I HIGHLY recommend this product. Update. 10-15-2023. Still in love with this thing. Our kitchen, indoor plants, and garage that leads to the backyard are all right next to eachother in 800sqft and this captures all the little flying critters that bite us and our plants and hover around our food and trash. Edit: Oct 2024. It has been running nonstop since day of delivery and house is still bug free. Update Aug 2025 : My unit has been running on high fan and high light settings practically non stop(we moved, tripped a breaker, and I cleaned it once) for over 3 years now. Not one single issue or failure with the device. It has been completely covered in grease as it was running in the kitchen for awhile and after cleaning it still looks brand new. No weird light flickering. No funky fan noises. Nothing. Nada. It's been perfect this entire time helping catch indoor plant insects and mosquitoes like an absolute unit. 5 stars

I almost never write reviews ...... and when I do it's cuz I'm mad.....and it's a bad review lol. I'm genuinely impressed by this thing. It's worked wonders to get rid of all kinds of annoying bugs in my room (ESPECIALLY MOSQUITOES THANK GOD).

The trap works, but there were some features that the older model had that I liked. For example, the trap was larger and covered the entire base of the trap, I like the tray design better but the fact that the trap has 30% less surface area compared to before is annoying. I bought extra pads with this trap and they were the wrong size... I guess you can cut them to fit but that is annoying. Also, the tray is stiff and while I understand the idea of not having to grab and move the whole unit to open the tray in the older model, the tray being stiff means you kind of have to do that anyway. I like cable placement but also feel like it lessens the use. For those who don't know, the older model had the cable going out of the back of the unit but in the middle of the device which left more room for the tray at the bottom. The newer unit has the cable going out of the bottom of the unit which means the dray has to be smaller to accommodate. I have tried using the scent pod, but I don't think my apple cider vinegar was good because it was too weak to attract anything. I tried drinking a little of it to test it later and found that it was practically juice so it was definitely not strong enough. My father has a great method of getting gnats though by using a little bit of red wine, the smellier the better (basically higher quality wine). Just take a cup and line the bottom of it with the wine and put cellophane wrap over top and poke a few holes. Also, a rubber band will help keep the cellophane tight. He never uses any soap so it is basically a gnat "prison" rather than a trap, but maybe if you add a tiny bit of dish soap, it will work better as a trap. I have also found that gnats are oddly attracted to fermented things, so maybe try taking a little bit of sugar and yeast to a cup and that might work as well.

Doesnt work

The product looked pretty well made, but UK buyers beware! It comes with a totally useless Chinese/ USA plug! So I've had to order an adaptor plug that is suitable for the UK, very poor! If I order electrical items for the UK I expect they are delivered with a compatible charger.

Ik kan het niet direct gebruiken wat er zit een 12 volt adapter bij met een US stekker. Dat verwacht je niet voor een product dat je gewoon in de EU besteld!

UK consumers, don't buy this. The seller is sending it out with power supply transformers for the USA, which are lower voltage, non-compliant and non-standard in the UK, they need to be sending out a transformer for 240v electrics, not 110v like the USA. This is how house fires start. I'm reporting it to Trading Standards, as this is quite dangerous and most people would just stick an adapter plug on the American plug!

Pas terrible, je ne recommande pas. Les insectes sont toujours là dans la même quantité
