I found that the strips work not only on windows but also inside the lid of of our kitchen trash receptacle. Gnats love that place, so we stuck a strip to the inner surface of the lid, and it collected dozens of gnats the first day. I used cellophane tape to attach the lower edge of the strip to the lid. I don't know why we had so many gnats this summer, but now their numbers are decreasing.

For some reason about a week ago, I had a serious problem with flies in the house. I’ve never seen so many and these strips on the windows really helped.

We get a lot of fruit flies in the summer (the humidity is INSANE) and this keeps those pesky things in check. It also catches a good number of house flies

The product is very effective at trapping flies and gnats. I have two on my window and three in the kitchen under the sink by the trash. The ones under the sink are catching the most at the source.

The Catchmaster window fly traps are an excellent product. We recently built a new home, and when we moved in it was full of flies! We couldn’t keep up with simply swatting them, so I did some research and found the traps online! The traps got great reviews, so I thought I would give them a try. We couldn’t be happier with the results! NO MORE FLIES! Thank you Catchmaster for the fine product!

These things have improved my quality of life by 100%. We have cluster flies and have to vacuum them up, but these catch ALL the flies. I don't know why, but once one or two get stuck, they all go there. Since they are clear, they don't obstruct the windows and the light attracts the flies. Amazing. Please don't stop making these! Ever!

Flies are now minimal in my house- as are ladybugs. Even the little gnats are now stuck!! What a relief!! Have been using these for 2 years now and except for a spider here and there— way fewer bugs!!

Best fly product I have ever used. I used it in an animal shelter. Put it up so they cannot get it. Best of all no chemicals

We have not installed our recent Catchmaster purchase, but we have used the sticky window fly traps in our sun room for several years with great results. We put one fly trap on each "transom" window above our 6 pairs of sliding glass doors, and they work very well to eliminate the many gnats and flies that try to share our 3-season room with us!
