I ordered stem flying insects arriving fast but I’m not satisfied with packaging because when delivery everything already opened and packaged of product all beating up.

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!”

Great product- totally recommend!
Love this product! Much cheaper than other brands with Target offered coupons and it works great! Fruit flies and moths are a huge annoyance this time of year. I put it right by the door and it catches them well! 10/10

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.

Great for gnats
These refill cartridges are user friendly and efficient. We get tiny gnats from our sinks and also from the soil of our houseplants. These refills keep them to a minimum.

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.

The Sticky Stayed
I was hesitant to order these refills for the plug in light trap in my kitchen because they're sticky stuff. It's 100 degrees here in central Florida presently. Almost everything melts in the mail. I was pleasantly surprised to see they arrived intact. Yeah!

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.

Does not work
Have had it plugged in for a few weeks now and it has not caught a single bug even though my house has plenty of gnats and other flying bugs. Would not recommend

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!

You get what you pay fot
Works great with out chemicals. The trap catches many types of bugs. Easy to use. Insert sticky strip plug in and forget it. Plus since it lights up it becomes a night light.

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.
