STEM Light Trap: Indoor Fruit Fly Trap, Effective Insect Control for Home, Attracts and Traps Flying Insects, Emits Soft Blue Light, Starter Kit with 2 Plug-In Devices and 2 Cartridges

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!

these work awesome and aren’t ugly to have out in open spaces and the light feature is great! Caught all my bugs and gnats haven’t had any issues with them since!

Zevo is much better...after you remove the paper your fingers are so sticky you need goo-gone plus the paper is hard to remove by an order woman

It definitely attracts & holds the bugs!! - ease of use : needs a cleaner way to remove paper backing, some sticks to the paper & or the fingers. Put a pull tab or something & easier to remove please??

Working well.

With 2 Guinea pigs that eat two 'salads' a day, it's bound to attract those small demons while driving me crazy in the process. I was on IG one day when I came across a post that was recommending these, so I jumped on here and ordered them. They have helped a lot, I even jimmy rigged one into the piggy's cage! I have probably seen a 60% reduction in the amount of fruit flies, and other random flying annoyances as well. If anyone knows of something even better, PLEASE LET ME KNOW. Until them, I am very pleased with this purchase and do recommend

Item is awesome. I didn't think I had bugs in my house but sure thing I do! Great product to catch those pesty flies and gnats.

Great product!
