Great concept, mediocre practicality.
[This review was collected as part of a promotion.] This fly trap starter kit had all the makings of really being something, and although it wasn’t completely worthless, I was disappointed on the efficiency. The light was entirely too bright during the nighttime, and it took a long time to “fill up” the first insert- more time than I have honestly. Still a great concept, I just think it could be improved a little.

Safe for pets
[This review was collected as part of a promotion.] “This STEM Flying Insect Light Trap is a lifesaver! I plugged it in and within the first few hours, I already noticed a huge reduction in flying bugs around the house. It’s quiet, safe for pets, and so easy to use. I love that it doesn’t use harsh chemicals yet still works incredibly well. The soft blue light attracts bugs without being too bright or annoying at night. After a full week of use, my kitchen and living room feel so much more comfortable and bug-free. Truly a must-have for anyone dealing with gnats, flies, or mosquitoes. Highly recommended!”

Scam
Don't waste your money. I’ve had this "trap" in my kitchen for a week, and the fruit flies are still throwing a rave like it’s Coachella. It doesn't catch anything! For $15, I basically bought a glowing nightlight for bugs to admire before flying away to breed more friends. If you want the same effect, just slap some double-sided tape on a lamp and leave it on overnight—you’ll save money and probably catch more. Don't get me started on the overpriced "refills". Target should remove this scam from their store ASAP.

Doesnt work
Used in small bathroom and kitchen and didn’t catch a single fruit fly. Only thing that got stuck was a ladybug.

Does not work for fruit flys.
The fruit flys are so bad this year so I decided to try this lamp. It has been plugged in for a week in my kitchen and it has not caught a single fly. I put out a bowl with a splash of red wine with plastic wrap and a few holes in it and I catch a bunch of flys within minutes. Don’t waste your money.

Good fruit fly catcher
Easy to set up. I found the location matters. I moved it to be closer to the kitchen sink and food prep area and it caught many more insects. I don’t think it will solve all problems, but it definitely helped.

Sucks
This product did absolutely nothing. I never write reviews but I thought everyone should know I had it plugged in for three days with nothing.

[This review was collected as part of a promotion.] I forgot to take a picture of this but it works so well. It’s worth buying and well designed and does not look tacky. No smell at all easy to install.

Great product
This actually worked amazing for the fruit flies around my house. I put them in all different rooms and it attracts them very well.
