Q: Does it make a zapping noise every time a bug enters the trap?
submitted by LD from CO - 4 months ago
A: I only hear it if it's a large bug or I'm standing right next to it.
submitted byK L - 3 months agoA: Thanks for your question. While no formal testing has been done regarding this, if you notice a zapping sound, we hope it's not an inconvenience. Enjoy your day! – Brooklyn, STEM Consumer Care

Q: Can I take this in my check in luggage?
submitted by Viki - 6 months ago
A: I recently brought a couple new ones home in my checked luggage. I would just make sure they're not on or can't be turned on mid flight.

Q: Many zappers claim to work on Fruit flies, but they don't work on the TINY ones that are 1-2mm. Will your product kill those TINY fruit flies? Glue traps and light traps seem ineffective on them.
submitted by fredthebeagle - 1 month ago
A: Thanks for checking. We'd anticipate this will be effective for your needs. Use this trap in garages, porches, sunrooms, lanais, entry points and for zapping insects hiding near plants or in enclosed areas like tents, sheds, pantries, and closets. Have a good day! – Brooklyn, STEM Consumer Care

One time wonder.
It’s small and cheap, but I used it once and it stopped working. I cleaned it, charged it, it was dead.

Waste of money! Do not buy this!
Waste of money! This bug zapper is useless. I have a variety bu zappers that are different brands and sizes. This one is a total waste of money. It is very small but the main problem is that it doesn't work. Avoid this product!

DO NOT BUY - Doesn't work and you can't return it
Defintely do not recommend buying this. It doesn't work and you can't return it. It never once attracted or zapped a mosquito. It was the only light on in the room overnight with several mosquitos in the room and did not catch any of them. Also used outside with mosquitos swarming and again nada. Don't waste you money. Buying would defniretly be a waste because you can't even return it for some unknown reason exept that's the "policy" on certain items, including this one. Except nothing ever told me that was the policy before I bought it.

Waste of money (even with the 50% off coupon!)
It does nothing… we use it in a darker space to attract mosquitoes, and we are still covered in bug bites. Finally just got clean-feel bug spray since it was incredibly ineffective

This thing does not attach bugs. I’ve had it out for several days and the flys literally land on top of it. Definitely not worth the money

Buy on Sale only.
It was able to catch some fruit flies but I don’t think it’s powerful enough to attract much else. For the full price I don’t believe it’s worth it. I was able to get it cheaper with a rebate I found on Ibotta. I’ll keep it inside our rv trailer.

Portable
[This review was collected as part of a promotion.] The noise level in portability is great. Safety is great because it’s covered and has a hook to hang it. The effectiveness is unsure since the rechargeable device isn’t long. So it’s more of like a charge it when you go outside to use it you’d bring it with you and then not sure the length of time it lasts before it dies.

Great
[This review was collected as part of a promotion.] I love this because it is very safe to be around kids. Is very easy to carry around and plug in. It's not have a bunch of noise. And it's very effective. And I love the fact that you can put it outside or inside.

Decent bug light
I keep it on at night in the bathroom due to seeing some small gnats flying around occasionally. Over the course of 2 weeks, there are several dead bugs in the grid. Recharge it during the day. Lasts all night. Better than nothing, but not as powerful as a larger bug light. Works OK in a small space. It is only about 7 inches tall.

Cute but
Adore STEM products, use them all. Was so excited to see a battery operated version. Unfortunately, did not work at all. Used it outside on patio during evening where there were hundreds of knats. Used it inside where we have used plug in Stem with success. Did not work. Not even for one small knat. Plus, no timer or alert that it needs recharge. Good idea but only disappointment.

Pretty good tbh
[This review was collected as part of a promotion.] If you live in a rainy climate like me (Florida) please bring this inside. One good rainstorm and this thing doesn’t work anymore 😂 it’s fine but it did work when it did. I did buy a replacement and I bring it in when I’m not on my lanai and I like it.

Works great
Works really well! The first night we used this outside it caught 15+ bugs, including some Japanese beetles. It also works well indoors for flies that are hard to swat. The only thing that could be improved is the hook shape, although I appreciate that it collapses.

DONT WASTE YOUR MONEY!
Anyone on these reviews claiming this product works was paid. That stem zapper does not zap any bugs. Don’t waste your time and money! I figured. I give it a try since it’s summer and you have bugs everywhere but I purchase two and no one has zapped anything.
