STEM Flying Insect Light Trap is an easy, mess-free option for attracting and trapping a variety of flying insects like house flies, fruit flies, gnats, mosquitoes, and moths. Use this discreetly-designed flying insect trap in any indoor room where insects are present, especially around fruit, trash cans, garages and entryways. Enjoy the odor-free, soft blue light technology that traps insects with no chemical insecticides. We crafted our moth and mosquito trap to be people, plant, and pet-friendly* for 24/7 continuous attraction. It’s easy to use and install. Simply remove protective peels, insert the dual-sided adhesive cartridge into the flying insect trap base, plug in to the wall, and position using the customizable 90-degree rotating plug and leave on 24/7. No need to touch any bugs or get your hands sticky. Replace the cartridge every month or when cartridge is full of bugs. This bug trap is compatible with Raid Essentials light trap refills as well. *when used as directed

DIRECTIONS FOR USE: Use in any room where you see flying insects. For household use only. 1 - Remove the protective peels on both sides of the refill. 2 - Insert the refill into the device base. 3-Plug the trap into a wall socket near common insect hangouts. The trap should be positioned UPRIGHT. When blue light is on, it starts to work. 4. Keep the trap plugged in 24/7. When full, unplug the trap and replace with a new refill. FOR BEST RESULTS: Place traps in areas with heavy flying insect activity and keep plugged in 24/7. Replace cartridge when it’s full of insects.

Q: There are two stem devices that look identical to me and have the same box but one is 19.99 and this one is 17.79 what is the difference? They both say they contain the device plus one refill. They have identical product boxes so I’m a bit confused.

Q: Will this help catch clothing moths? They are so hard to get rid of.

submitted by Ash - 2 years ago

  • A: Get Cedar wood blocks. Moths do not like the smell of Cedar.

Q: Are there refills included with this trap?

submitted by Mountain woman - 2 years ago

  • A: I have not purchased it yet but per the picture, it says one device and 1 refill so I assume you are paying for the device and 1 cartridge rather than having to buy the device and get a cartridge.

    Small, quiet and actually works!

    [This review was collected as part of a promotion.] The little STEM trap is honestly doing its job. It covers my kitchen area well, doesn’t make any noise. Cleaning is literally just pulling out the refill. Plus, it’s tiny, so storage is no problem.

    It works!

    [This review was collected as part of a promotion.] I’m really impressed with the Stem insect light trap. It’s super easy to setup, quiet and doesn’t have any messy sprays or odor. It has already caught many bugs. I also like that it’s discrete enough to keep it plugged in anywhere.

    Absolutely Wonderful

    [This review was collected as part of a promotion.] Amazing performance. Flying insects are pulled to the blue light this emits. We put it in a lower plug on the wall in our kitchen. We were surprised at the amount of Nats it traped. It is safe for pets as it didn't bother our cats. I do recommend this product as it is safe, effective and really does work.

    The Simplest Yet Most Effective Bug Catcher

    [This review was collected as part of a promotion.] This is one of my new favorite gadgets around the house. It's set up is so simple yet it's a powerhouse when it comes to catching bugs. The light is not extremely bright so that it grabs everyone attention and it's so easy to refill the traps when they are full.

    Highly recommend

    [This review was collected as part of a promotion.] This product works great for catching flying insects! I just moved in and had the door open which let a lot in, and they were all caught within a few hours of me setting this up. It looks fun with the blue light casting on the walls at night, and doesn’t take up any significant amount of space.

    Caught huge flies

    [This review was collected as part of a promotion.] We live in California and there aren’t as many bugs flying around as there are in the South, but we do have huge flies. I am impressed this caught 3 huge flys! Thats a win! Super easy to install and change the sticky pad. Great value.

    Easy to use, quiet and effective at catching flying insects indoor

    [This review was collected as part of a promotion.] I’ve been using the STEM flying insect light fly trap starter kit and i’m impressed with how easy it is to use. Setup only took a minute. Just plug it in and insert the refill. It works quietly, doesn’t have any strong odors and helps reduce flying insects indoor without the need for sprays. The compact design blends in nicely with my home, and the refills are simple to replace. It’s a convenient, low-mantenience solution that i would recommend to anyone looking for an effective indoor insect trap.

    AMAZING product! Beautiful blue color and SO effective against little pesky bugs

    [This review was collected as part of a promotion.] AMAZING PRODUCT! If I could give it 10 stars I would. I didn't even know I had that many little bugs flying around my kitchen and this product finds them all. I was shocked to see how many bugs it collected. I haven't seen a single bug in my kitchen since plugging this light in. Even better, the blue light is SO cool and soothing. I love the ambiance it provides when the light is off. So much nicer than a regular white light. I'm going to buy this for every room in my house!

    Works alright but I've had better

    [This review was collected as part of a promotion.] I like the idea and look of this fly trapper but it doesn't seem to work as well as the other brands I've used. Its easy to change out the refill but they dont stay well if I knock it the refill plate would probably just fall out. If it was closer to the wall and more encapsulated the bugs would get stuck but its set up like a night light

    So effective!

    [This review was collected as part of a promotion.] The STEM Flying Insect Light Trap has been a lifesaver! My kids constantly ask for fruit, then don’t eat the fruit that they just had to have. Our kitchen was being taken over by fruit flies and we had tried all the hacks to stop it. None of it worked. This trap solved the problem very quickly! It’s so simple to use and takes up minimal space. All you need is a free outlet. The traps are double sided, so it allows for maximum trapping. Will definitely be keeping this in our kitchen!

    It works i recommend it

    [This review was collected as part of a promotion.] Easy to put together, the refills are double sided sticky for the flys to go towards the light and get trapped on the sticky part. This is great for the kitchen in the summer because i get fruit flys where our fresh produce sit.

    Easy to use, but not very effective.

    [This review was collected as part of a promotion.] I like that this trap is easy to set up, quiet and doesn’t use harsh chemicals, so it feels safer to use. The blue light is also not overly bright. Unfortunately, I still see plenty of live bugs flying around the area, so I don’t think it’s as effective as I hoped. It might work for a few insects but it hasn’t made a noticeable difference for me.

They work so well keeping the gnats, small bugs out of your home! It is very easy to set up and to maintain! The size fits great in our kitchen and the blue light is not crazy bright either!

    This product is great

    [This review was collected as part of a promotion.] I received this product for free in exchange for my honest review. This STEM Flying Insect Light Trap works really well! It’s very easy to use—just plug it in and let it do its job. The UV light does a great job attracting insects. The first time I used it, it filled up really quickly with mosquitoes and other flying bugs. Now that mosquito season is slowing down, it doesn’t fill up as fast, but it still helps keep bugs under control. I also like that it doubles as a soft night light, which is a nice bonus. I love that it’s chemical-free, safe to use around people and pets, and replacing the refill is quick and easy. Overall, I’m very happy with it and would definitely recommend it!
