[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.

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.

Very sticky trap refill!! Recommended!
[This review was collected as part of a promotion.] These are effective refills for the Stem brand light trap. I was hesitant using a new brand but clearly it did a good job of catching fruit flies after just 4 days of being on vacation!! I will definitely be buying these again. Super easy to install in the Stem insect trap. Highly recommend if you have an indoor flying bug issue.

Amazing!
[This review was collected as part of a promotion.] The STEM flying insect light trap refills are extremely effective in eliminating the gnats and flying bugs in our home! I keep ours in the kitchen near our fruits and vegetables. These refills are very sticky and easily trap the gnats and other insects. I have noticed significantly less flying bugs in our house since using this product. It’s easy to change out the refills- and they last for a good while before you need to change them!! Definite...

Just remove and replace that's simple.
[This review was collected as part of a promotion.] The attraction of the blue light is so good and very convenient at night, specially at the kitchen. It doesn't have any odor plus the coverage is great, the installation was super easy and there's no cleaning you just remove and replace with a new trap refill.

Works great!
[This review was collected as part of a promotion.] Super easy to replace! We have the light trap and we love it! The refill is the same as what comes with the original kit and takes a second to change out. No more fruit flies and gross house flies!! They love the trap!

Easy-to-install refills that help keep the device working at a reasonable cost
[This review was collected as part of a promotion.] The refill cartridges are very easy to replace and fit perfectly into the device. I like that they come ready to use, and changing them only takes a few seconds. Since there aren’t many flying insects in my area right now, I haven’t been able to fully evaluate their performance yet. However, I appreciate that I can simply replace the cartridge instead of buying a whole new device. I also think the refills are reasonably priced, making it afford...
