I wanted these to work, but they don't catch well at all. Used two of them in a normal sized kitchen to catch little gnats and flies, but I still had to killl them the old-fashioned way. After 3 weeks you could count on one hand the gnats these caught so I got my $40 back.

Zevo trap doesn't seem to attract gnats at all like they avoid the blue light.

Love these. Purchased some beautiful larger indoor plants and they came with gnats. Using these allowed me to get it under control while I took care of the gnats.

Looks sleek and I thought great I'd purchase this and it'll be a discreet way to get rid of the flies. But it's non effective. Didn't kill a single one or deter.

Bought this two-pack of the fly traps to use in my small greenhouse to control flies and gnats that constantly enter it. The traps worked much better than I expected. I put the two traps in the greenhouse at 6:00pm, and when I checked them at 8:00am the next morning both traps had captured over 10 gnats each. Looking forward to continued control of gnats and flies in the greenhouse.

We are having so many problems with gnats this summer! There is lots of construction around us that seems to keep them stirred up. We couldn't walk into the house without "a million" of them coming in with us. They were all over the porch & doors in both the front and back. This (+ Dynatraps outside) has made all the difference. Great product!

We hate those pesky flies in our house so we ordered this online. Soon as we got it we plugged it in and within an hour it got two flies. We were amazed for sure. Now its still catching them and we are pest free when they get in the house. Fixing to order more refills to go with it.

Sams is the best place to buy these! I bought one from HD and it was almost the same price as 2 with 6 refills from Sams! They do work, within a day of plugging them in they were catching mosquitoes and small flying bugs. I would highly recommend them.

Buy this if you have gnats! It works like a charm

[This review was collected as part of a promotion.] I love this product as I do not have to purchase any insect killer sprays which I believe are very harmful and secondly it is very easy to use and a long lasting thing as I only need to replace the cartridge whenever it gets full with insects.
