STEM Flying Insect Trap - Indoor Fruit Fly & Gnat Catcher for Home, Kitchen & Any Room, Attracts & Traps Bugs, Soft Blue UV Light - Includes 1 Plug-In Device & 1 Cartridge

I purchased my first set of this specific brand thru a different retailer when they were on sale. They worked so well I had to order refills almost immediately and then bought two more of these devices from Amazon. When I initially set up the devices, I waited 24 hours to see if they caught anything. The sticky pads were completely clean. I filed a return request and then packed one up. I moved the other device to a different room, just in the hopes that maybe, MAYBE it'd catch something there. And boy did it. Holy smokes. The other one caught so many flies it looked like the sticky pad had been dipped into a jar of flies (where my Alice in Chains fans at? lol. But seriously...). I cancelled the return request, unpacked the second device and moved it into different room than where I had placed it previously, where it ended up working very well too. Here's some advice if you're not having luck with these: 1) Place the device in a room where it won't be competing with other light sources, especially sunlight. For instance, there're no windows in my bathrooms, neither one gets very much light from any nearby windows, and it is absolutely comical how many flies the devices catch in there. When I initially set them out, they were in my kitchen, which is open to the living room with a large window in it, so they both receive a lot of light for nearly 2/3rds of the day, so these devices did not catch anything there. 2) To really be effective against fruit flies, take away competing temptations such as food and places to lay eggs. And I do mean FORGET the finicky home made vinegar traps that seem to trap only a few, less evolved flies dumb enough to try to land directly on the liquid, and just feeds the rest (who thank you, btw). If it's possible for you, store fruits and veggies that you might typically keep out on your counter or wherever in your fridge until the population has been reduced. If you are able, only throw "dry" trash away in your trash bins (non-food related paper type stuff), and throw "wet" trash such as food discards and wet paper towels into smaller grocery bags (maybe double bag it tho) and place that bag in the refrigerator or freezer, somewhere where it's not coming into contact with food and beverages, until you're ready to put it outside your home to be collected. And if you're wondering what to do for areas that do have competing light sources, personally I use the SafeHome uv type devices and they work very well where the STEM ones don't. Or, get yourself a nice fly swatter, wait for them to congregate on a window or a large white surface during daylight hours and then smack the crap out of 'em. You'll of course need some glass cleaner and newspaper or other wipes to clean the surface afterward, but such is the price of fruit fly war. I hope this helps!

This product is cheap and reliable as if you have any bugs in your house or in your bedroom that keep on buzzing in your ears. Just get this and don’t get attracted to the blue light and then die things to the sticky paste that is on the product 10 out of 10 highly recommend.

This really traps gnats

Very happy with these. My father's house had some insect issues and this has definitely cut down on the infestation. It works very well at attracting and capturing the little buggers. No noise what so ever and good value for the cost.

Works great put in my kitchb

I keep a fair amount of fruit in my home, and with fruit comes fruit flies. I usually use the homemade methods but grew tired of smelling ACV and wanted to try one of these plug in devices. I happen to catch a great deal on this one yesterday and gave it a try. I was frustrated initially because it didn't attract any on yesterday when I plugged it in. When I woke up this morning, there were three stuck to it. I think it may work better during the nighttime because, the light is so very bright on the thing and the pad is extra sticky, the gnats don't really stand a chance trying to do their gnaty deeds. I can't speak to actual house files and other insects because I only have gnats and this thing works very well, for me.

These attract bags such as gnats and fruit flys extremely well. The only detractor is cost.

Bright blue night light. Does not trap mosquitoes
