What Customers Are Saying
Customers overwhelmingly praise these insect trap refills for their powerful stickiness, effortless replacement, and chemical-free operation. Most highlight the intense adhesive strength that traps gnats and fruit flies effectively, with many reporting visible results within days. Reviewers consistently note the simple, mess-free replacement process requiring no tools and taking seconds. The double-sided design, long-lasting performance of a month or more, and subtle blue nightlight are widely appreciated. Several value the safety for pets and absence of odors. A few report inconsistent bug attraction or wish for thicker adhesive, but these concerns are vastly outweighed by positive feedback.

Doesn’t Catch All Bugs
[This review was collected as part of a promotion.] The product does what it’s supposed to but disappointed in the amount of bugs it has actually caught. It has more dog hair on it than bugs. Would stick to another brand.

Helpful
[This review was collected as part of a promotion.] No odor at all, size is perfect fit and performs very well. Esthetically pleasing to the eye for what its for. The blue light seems to help guide bugs to there too.

Works
[This review was collected as part of a promotion.] The setup is fairly easy you just place the refill In the light. It doesn’t make any noise and the size is perfect. The consistency is sticky so the insects get trapped and also the disposal is fairly easy.

So helpful!
[This review was collected as part of a promotion.] The Stem Flying Insects Light Trap Refills have been a life saver! We have been growing garden seedling inside and our potting soil had fruit flies in it from the store which have repopulated. Putting the refills in was so easy to do and throwing them away after they are full is great. The light itself can be used over and over with the refills and it is safe to use at home with kids and pets! Love this!

Easy to replace, long-lasting, and effective at trapping flying insects.
[This review was collected as part of a promotion.] These STEM Light Trap Refills are easy to replace and fit perfectly in the device. They stay sticky for a long time and do a great job trapping flying insects like gnats and fruit flies. I like that there's no mess, no strong odors, and changing the refill only takes a few seconds. They keep the trap working effectively and are a convenient replacement.

Easy setup and works great
[This review was collected as part of a promotion.] These light trap refills work great. They are easy to install and dispose of when done. I have only been using the light trap for a couple of days and it is already working great. I’m confident one refill will last a long time.

Must have
[This review was collected as part of a promotion.] I really like this product. I keep it out in the garage. Being that it's summer time right now, there has been a lot more bugs. This definitely helps in getting rid of them.

Great product
[This review was collected as part of a promotion.] Easy to use refillable materials and decent coverage. Uses power and light to attract unwanted critters and easy to refill design. Just peel and set product in light source.

Easy to assemble
[This review was collected as part of a promotion.] The assembly and disposal of the refill is so easy and practical. This product does wonders to get ready of visible and invisible insects around your house. The refill lasts for days and is increadible the amount of insects it gets rid of.

Works great, just watch your fingers during setup!
[This review was collected as part of a promotion.] Very effective, but super sticky cartridges. It would be nice if there was a better non-sticky edge to hold onto. Other than that, it's a fantastic product and I'd recommend it!

Good product
[This review was collected as part of a promotion.] This was a good product. I enjoy using it as easy to set up. I’m glad to have extra refills to catch those pesky flies and bugs. It’s lightweight. It has sort of a blue filter and it has no sun which I appreciate.

Works great!
[This review was collected as part of a promotion.] These trap bugs with a sticky substance on the fefill pad. These have a nice border to hold so your hands don't stick. It's very easy to use and easy to clean up, you just throw away the refill. I recommend this product.

Not very effective, caught only 1 bug in 2 weeks
[This review was collected as part of a promotion.] I’ve been using this product for nearly two weeks now, and the results are very disappointing. It has only managed to catch one insect so far, even though I still see many fruit flies and gnats around the area. I followed the instructions and plugged it in a good spot, but it just doesn't seem to attract them well. Two stars because the blue light looks okay, but it fails at its main purpose.
From stemforbugs
It handles both large and small insects excellently.
[This review was collected as part of a promotion.] I've been using this product for two weeks now. It catches not only small insects but also handles palm cockroaches effectively. I'm terrified of insects and creepy-crawlies, but with this trap, I don't feel scared.

Easy peasey
[This review was collected as part of a promotion.] So easy to change out. Minimal packaging! Great design. Looks so sleak and would never know its a gnat catcher. Just looks like a peaceful glowing night light.

Easy to use!
[This review was collected as part of a promotion.] Easy to replace with replacement refill when needed. They do last a long time. Easy to change and throw out. There’s a part to grab that isn’t sticky.
