Stem light trap

It was a waste of my money, insects (fruit flies) it was as if the insects if they could speak 🗣️ would say “guys I fly and land all around this gadget and it doesn’t attract me at all”. So needless to say it’s been up a whole week and hasn’t sizzle not 1 fruit fly!!!

Not Bad!

Seems to be good at catching fruit flies and knats, but not 1 real house fly has been caught. Have not tried the main competitor's system yet. Bought this because of price and number of refills included. Have only been using for a few weeks thus far.

Great deal and can’t stop using them!

These work, especially for pesky gnats! I’ll never stop buying them. It’s also a calming nightlight for the bathroom - dual uses! The photo proves it all.

Not very effetive

I haven't seen many flying creatures attracted to the light. At least not many victims on the sticky paper.

Excellent Project

Couldn’t believe the amount of flying insects it caught in the first 12 hours in our kitchen . I was so impressed that I bought a second one for our basement!

Great find.

Placed a new one on a day we were constantly going in and out of house. 5 flies caught over night. Works best when room is dark and that’s the only light.

One Expensive Night Light

Absolutely zero bugs were trapped. It's an expensive night light.

Worth the money.

Worked like a charm w annoying gnats near my plants. I ve been overwatering turns out. These little blue sheets are amazing! One round of two inserts did the job. So happy.

It works

I don’t know what other people’s expectations were, but I expected to see dead bugs on the glue traps. I’ve now used these in 2 homes in 2 different areas of the country (cold %26 dry vs hot %26 humid), and they work the same in both places: they trap bugs on the glue, where they die. I’ve gone through all of the refills they’ve come with multiple times, with them all being covered in things like fruit flies, moths, houseflies, mosquitoes, gnats, etc. THEY WORK! When the traps get full, I change them out. No problem. If they’re full, bugs avoid them. They’re great in kitchens and bathrooms. I’m now testing them in other rooms. Hopefully, they work just as well in those. Refills beyond what comes in the box are no problem, either, they just come from a different store. *I’d have included photos of all the dead bugs on mine, but I literally just changed out the boards last night. Sorry…
