[This review was collected as part of a promotion.] The refills are very effective for the product. It was very easy to set up. The only bummer is that since it isn’t insect sticky trap, it is single use plastic and cannot be cleaned.

Be Careful around children
[This review was collected as part of a promotion.] I bought the refills thinking they wouldn’t last very long, but each one actually lasts more than a month. It’s a very good insect trap. Just be careful around kids

Plug it in, walk away, and let it quietly clear your home of fruit flies and gnats with zero effort or chemical smell.
[This review was collected as part of a promotion.] This STEM light trap is a game-changer for dealing with annoying indoor bugs. I plugged it in and completely forgot about it, but checking the pad a few days later showed it caught an unbelievable number of gnats and fruit flies effortlessly.

Works Very Well
[This review was collected as part of a promotion.] I'm really happy with how well this STEM flying insect trap works. It was simple to set up, and I started noticing results within the first day. It caught several small flying bugs, including pesky gnats and fruit flies. The blue light is a nice feature and seems to do a good job attracting the insects. I placed it in my kitchen near the fruit bowl, where I usually notice the most bugs, and it has been a helpful way to keep them under control.

The insert is doubled sided
[This review was collected as part of a promotion.] I been using STEM Flying Insect Light Trap for a full month and it works as well as the z brand. I have both brands to compare and I must say they do the same job. What I like is that STEM insert is doubled sided and more budget friendly than the Z brand that's single sided. I used it in my kitchen and it works well as a night light too. They caught around the same number of tiny insects in summer. I would recommend to give it STEM a try.

It has adhesive on both sides
[This review was collected as part of a promotion.] This product comes with two flying insect trap, and I really liked it because it had double sided glue and it was excellent for catching mosquitoes. I have been using it for over a week and it is still effective. I enjoyed using this product because it works as expected and is really affordable.

Practical Solution for Fruit Flies
[This review was collected as part of a promotion.] The blue light is very bright and the refill trays slide out and lock into place with very little effort making it super easy and quick to setup. The adhesive is also very sticky (which is good!) and I didn't notice it losing any stickiness over time. I tested it for over one month and didn't end up catching anything, but if you are constantly swatting away fruit flies in your kitchen, then I definitely think this product is worth a try!

Captures insects!
[This review was collected as part of a promotion.] I’ve been using these trap refills for the “STEM Flying Insect Light Trap,” and think that it works great. The refills are extremely easy to replace and the sticky is super power so that once insects get trapped, they really can’t escape. The trap has been doing its job well and caught several fruit flies in my kitchen. Overall, I would recommend this product and give it a 8.5/10.
From stemforbugs
Sticky on both sides
[This review was collected as part of a promotion.] Refills are sticky on both sides to try to catch as many bugs as possible. They are easy to switch out and you can simply just throw the used one away.

Slide in quickly🦟
[This review was collected as part of a promotion.] I’ve been using these refills for a while, and they make keeping the light trap going super easy. They slide in quickly, no mess, and they start catching those tiny kitchen flies almost right away.I like that I don’t have to think about it much, just swap a new one in and it keeps everything under control
From stemforbugs
Easy to replace the refills
[This review was collected as part of a promotion.] After almost a month of using we simply removed the trap and replaced it with the refill. It was very easy. The product has no smell and it's very sticky, so you you have to be careful to not touch it but there are non sticky parts that you can grab it with.
From stemforbugs
Very very sticky
[This review was collected as part of a promotion.] The refills are intensely sticky. Be careful not to get it close to your hair or clothes. Speaking from experience. Perfect to catch flies though. They’re easy to replace into the fly trap itself. They’ve caught a couple little flies but not as many as I’d hoped.
