Description

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. Check refill often and dispose of it when the cartridge is full of insects. Replace refill every month for best performance.

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.

    submitted byGreat grandma M - 2 years ago

  • A: Great question. STEM Flying Insects Light Trap is a great option for all moths. However, this will only be effective against adult moths.

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.

    This item doesn’t work. I have had it for a week and have kilt more gnats with my bare hands.

    This trap is genuinely the only thing that worked for a fly problem. I tried just about everything to get rid of them and this was my last resort. I definitely recommend this trap to anyone struggling with pests. Only took about 24 hours to get results, so worth it!

    Surprisingly Effective and Quiet Fly Trap

    [This review was collected as part of a promotion.] I recommend this fly trap! The setup was quick and easy, and the instructions were simple to follow. The design is compact and modern. The blue light attracts flying insects really well and I noticed a clear difference after the first couple of nights. It works silently. And I think it's a great value for the price.

    Very sleek

    [This review was collected as part of a promotion.] This is very sleek. The refill is really sticky. Like really sticky. Any bug that lands on that is never getting loose. My finger barely on it twice trying to get the paper loose. I placed it in the kitchen. I like that it isnt bulky. I turned to the side and the blue light is for sure going to attract any creepy crawlies.

    These work... most of the time

    [This review was collected as part of a promotion.] I have used these in the past so I know they work. I put this one out last night and got 3 little fruit flies on it in 12 hours. A little disappointing since its next to my fruit bowl which has tons of fruit flies. Hopefully it gets more tonight!

    Great for kitchens!

    [This review was collected as part of a promotion.] It's super easy to set up—just plug it in and let it do the work. It quietly attracts and traps gnats, fruit flies, and other flying insects without any strong odors or messy sprays. I also love that it's safe to use around people and pets when used as directed. If you're tired of annoying flying bugs, this little device is definitely worth trying!

    Cheap & Effective

    [This review was collected as part of a promotion.] Pesky bugs don’t stand a chance in this house. I love the concept of this fragrance-free, noiseless, natural trap. No sprays, no chemicals, no mess. The cartridges are easy to install and are super sticky! These will last a while, but the price point is great for refill.

    Great nightlight

    [This review was collected as part of a promotion.] This stem flying insect light trap starter kit did not work for me I plugged into my guest bathroom where the most flies/gnats are and it did not catch anything. It is easy to set up and easy to use this may work for you but it did not for me, I do like it for a nightlight though so that is a plus! It has a slim lightweight design with no noise or odor.

    Light seems to interfere.

    Doesn't seem to attract flying insects when there is light. I plugged ours in over a week ago and nothing during the day. We've actually coaxed flies up to it and they just buzz away from it. We moved it to a darker area of the kitchen and things really didn't improve. However, when we wake up in the morning, we find insects stuck to it.

    [This review was collected as part of a promotion.] These are great for flying insects! Just one easy to step to put it together and plug in. I put it right next to our back door to catch the flies that come in when the door is open.
