Great concept, mediocre practicality.
[This review was collected as part of a promotion.] This fly trap starter kit had all the makings of really being something, and although it wasn’t completely worthless, I was disappointed on the efficiency. The light was entirely too bright during the nighttime, and it took a long time to “fill up” the first insert- more time than I have honestly. Still a great concept, I just think it could be improved a little.

Safe for pets
[This review was collected as part of a promotion.] “This STEM Flying Insect Light Trap is a lifesaver! I plugged it in and within the first few hours, I already noticed a huge reduction in flying bugs around the house. It’s quiet, safe for pets, and so easy to use. I love that it doesn’t use harsh chemicals yet still works incredibly well. The soft blue light attracts bugs without being too bright or annoying at night. After a full week of use, my kitchen and living room feel so much more comfortable and bug-free. Truly a must-have for anyone dealing with gnats, flies, or mosquitoes. Highly recommended!”

With buying
[This review was collected as part of a promotion.] I forgot to take a picture of this but it works so well. It’s worth buying and well designed and does not look tacky. No smell at all easy to install.

Love It
[This review was collected as part of a promotion.] We put this next to our fruit bowl to catch any stray fruit flies or bugs that may come in with the fruit and, as you can see, it works! Highly recommend.

Great
[This review was collected as part of a promotion.] I love these products you can use inside just as simple as plugging them into the outlet. We had a different brand that wasn't very effective but this one seems a lot better to use.

Effectiveness
[This review was collected as part of a promotion.] I have small children who are often bitten by mosquitoes, and the bites are very strong. This product has made life much easier for my children. We have been using it for 2 months, it is quite durable and of excellent quality.

Love it
[This review was collected as part of a promotion.] I like it. I keep it by my front and back door. I went and bought another be cause I liked it so much. It works. It has actually reduced the amount of bugs that come in. It’s pet safe. My cats don’t even realize it’s there.

Stem insect trap
[This review was collected as part of a promotion.] We have been having a really bad problem with fruit flies near my son's diaper genie. I put the stem flying insect light trap right above it and wow what a difference. Yaaaaay. Those things were getting so annoying. So happy to find something that finally works. This is a new need always in my house. Atleast for as long as my son is in diapers.

A Summer Necessity!
[This review was collected as part of a promotion.] I was a little skeptical about this, but right as summer hit the south with all of its humidity, I opened this and it was a game changer. From having fresh fruit on the kitchen table to having cookouts. This has cut down on the fly situation. The kids opening and closing the door, some always manage to creep inside. This is worth buying.

Easy to use
[This review was collected as part of a promotion.] It works. We live in Florida and have dogs and open our doors constantly and always have all types of bugs in the house. This helps keep them at bay!

[This review was collected as part of a promotion.] i LOVE these little bug catchers. they are so effective at grabbing bugs without having to have smelly apple cider vinegar out on your counter, which is also just gross to look at. i highly recommend to anyone!!! and honestly you can go so long without switching the panel

Great, but easy to mess with if you have littles at home.
This thing works: The sticky part is pretty exposed. I suggest putting in a high outlet where pet hair and little hands are absent.

Buyer Beware of Expensive Fake Products!
Very honestly Reviewing this Product… It DOES NOT WORK AT ALL… Therefore, I have to believe that this company is paying people to use for free & giving FALSE/POSITIVE REVIEWS!!! Now… After a sticky pad fell out of plugged in contraption… A few bugs that were crawling on the floor… actually did stick to the replacement sticky pad! As far as the Devices that have been plugged into the bathroom & kitchen outlets for 2 months… There are NO FLYING BUGS THAT HAVE EVER BEEN ATTRACTED TO EITHER DEVISE… This is an EXPENSIVE & FRAUDULENT/FAULTY PRODUCT!!!

Didn't work for flies...
It didn't attract flies at all (on day 3 with 2 plugged in where flies tend to congregate the most, still flying around the house and not on trap.

Product works great!
Love this product. We have gnats by our fruit that we never can get rid of. I pulled the light in near the fruit and the sticky mat caught them along with a fly. Definitely will buy this again especially for our camper.

Great product.
It started working within an hour and works great! My only complain is that the light is bright but I know that's what attracts them. I have it in my room and unplug at night due to the light being so bright. Other then that, works amazing!

Did not work for me.
[This review was collected as part of a promotion.] Unfortunately, this product didn’t work for me. I used it in a location where there’s lots of mosquito and none were caught. It is very quiet, but very bright so may not be great for intentionally dark bedrooms. Not a product I would purchase.

Very bright, does attract flying insects
[This review was collected as part of a promotion.] I love that this plug-in has no chemicals or odor. The light is pretty bright, so I keep this plug-in down in the basement away from where we hang out. This area is not where we get the most flies, but there’s a few flying bugs on the sticky sheet each month I’ve replaced it. For the price, it’s fine to have. However, I wish that it was not so bright. It’s kind of blinding.

Fair light fly trap
[This review was collected as part of a promotion.] STEM flying insect fly trap is convenient, easy to use and durable. It is safe to plug in and is fairly effective. It is very comparable to other similar products.

Scam
Only 2 devices and two sticky pads. It's cheaper getting them separate than this so called value pack. Each unit right now is $15 so for $30 you get the same as what you get here but this value pack costs $7 more. I thought this pack included 2 units and 2 refills. Each unit sold separately includes a sticky pad so why would you call the sticky pad that comes with the unit a refill? Refill means replacement, like an additional pad once you have to change it. The only pad included shouldn't be called a refill. Get it separately, this value pack is more expensive.
