Doesn't work as well as I expected but still does a good job of eventually trapping the flies. Took a few days for it to really kick in for some reason. Overall did an okay job.

These were very well to catch small flying insects. I use them in the garage and around the house.

Catches all the pesky little bugs!
The amount of gnats, mosquitos, and fruit flies this trap has caught has been amazing. It also operates great as a night light. We keep ours in the kitchen. So glad I purchased this and will continue to use.

These WORK
Very happy with these. We RV full time------ and these are extremely compact, easy to travel with, and they're effective!! We're currently staying next to a lake which means there are plentyyyyyyy of little bugs to catch. During summer season we may change the trap once a week. But it really does vary on how buggy the area you're in is. I do look for sales as they're not cheap persay. Still happy with the product.

Works amazingly
Lasts forever and grabs all the pesky gnats and moths. Pictures are front and back and this has been on for more than a month and the stickiness still holds.

Works great to catch bugs
These work great and have caught a lot of flies for us during the summer when it can get really bad in our house. They are also not too big so doesn't take up too much space. I just wished it sticky part of them would last a little longer but that is probably more because we had so many bugs.

They work for less $
Catches mosquitos, gnats and other small insects. Ignore the "user error" reviews and decide for yourself.

Buy Zevo brand instead! Ineffective for fungus gnats!
UGH. I was hopeful that this would be a great product! This summer, I bought some new houseplants from a local home improvement store, and some FUNGUS GNATS hitchhiked into our home. I had never heard of these little bugs until our recent invasion… They are tiny… They are nimble… They easily evade the frantic claps of the humans trying to kill them! I was hoping placing a STEM trap near the plants would help- but in the course of a week, this trap literally looks BRAND NEW. Didn’t catch a SINGLE BUG (fungus gnat or otherwise)!! I gave up and bought several ZEVO brand traps at that point and installed them near my plants as well as near our kitchen sink/window ledge (where I have some more little plants/starts). THE DIFFERENCE WAS NIGHT AND DAY! Within an HOUR, I had multiple dead fungus gnats safely trapped inside. IN ADDITION, the outside of the STEM traps are sticky, which could definitely be an issue if you have children or pets in your home!!! The ZEVO traps lure bugs into the INSIDE/BACKSIDE of the trap where the sticky (and easily changed) panel lies. ZEVO has both a wall trap similar to this STEM trap, or you can also buy the ZEVO Max, which looks like a little fragrance diffuser or tiny tabletop HEPA filter and contains not only a light to lure the bugs in, but TWO sticky internal panels to catch the little beasts! We’re still trying to kill the fungus gnats once & for all, but with Zevo traps in our home, we’ve reduced that number by 90+%!! HIGHLY RECOMMEND buying Zevo brand traps and passing on the STEM brand!

Takes too long to work.
It did capture insects but it took a few days to even start, I put a wedge of lime to attract the Nats.

Buy something else
Compared to my Zevo this one doesn’t really work, it only catches some. Don’t spend your money in this one.
