Real Pictures When in Use
Why Window Fly Trap?
Flies have a strong phototaxis, it likes to fly toward the light. Houseflies, in particular, often enter the room to eat and drink enough and then attempt to escape. They often regard the bright glass window as an escape route, but the fly can’t see the glass, so it hits the glass head on.
Please note:
Window Fly Trap Working Principle: Flies are phototactic and fly towards the outdoor light, getting caught by the transparent adhesive panel. Does not work on walls or dark windows.

Great value!
I bought a box 3 summers ago and they work very well for what they are. Pros: They work! They work best when the outside light attracts the flies to windows and they get caught trying to get out. They are VERY sticky there is no escape. They are easy to apply. They last a long time! I’ve put up 3-5 traps on my windows each summer and they catch them for most of the summer. One box (30 traps) has lasted me 3 summers with lots of flies. They catch fungus nats and house flies of all sizes, basically anything that flies and is attracted to outside light. I appreciate how these are translucent and let light pass through. They are more affordable than Zevo. There is no smell (and I’m VERY sensitive to smells). They work without taking up precious plug space, and electricity. Cons: Gross, just gross having plastic sheets of dead and dying flies stuck to the windows, but better than having these in a-holes flying around in the house, bleh! Cats will be attracted to live ones stuck and will try to bat at them and possibly get stuck (you’ve been warned!) so keep that in mind when placing these. Despite what the listing claims, there is some residue left when they are removed, but not enough to not recommend them or even remove any stars.Overall: I highly recommend! and I’m buying more after 3 years of use.

Great flycatcher!
They work really well and easy to use. They stick easily and easy to remove. I canât believe how many flies I caught!. The best thing is that you canât see them. I put them behind the shutters then left the shutters open a little bit so the flies can go in. Then they stick on the flypaper. Highly recommend.

Worth the Money!
This product is definitely worth the money. It is easy to use and very effective. I stick one strip at a time to the window on my back door. This way, my catches arenât on display for everyone else. It is nice and sticky and lasts. I just changed it today and it had several fruit flies, 4 house flies, and many more tiny insects on it. I know that sounds gross but itâs better than the flies reproducing and continuing to fly around. Itâs also better than using a swatter to kill them on various surfaces of my home. How long itâs left up depends on how big the problem in the house is. I donât have an infestation so it traps what sneaks in through doors that are opened through the day. I change it maybe monthly or so. I did have a fly issue prior to using this product – I was swatting a dozen flies a day and they were so annoying. I could not figure out why it was so bad. My house was clean, no food left out, etc. but flies reproduce so quickly, it does not take long for them to become a problem. I highly recommend this product if youâre dealing with any kind of fly annoyance in your home.

Very high quality…A must buy!
They work awesome. I can’t recommend this enough.It catches lots of various types of bugs and lasts about 2-weeks.It’s crazy, but the more bugs that are caught, it seems to attract even more!Easy to use and never leaves adhesive on the window.I have re-ordered 3-timesn now.

Great for pesky flies!
These are a game changer. They do a great job for something that just sticks to the window. They can sometimes leave a sticky Residue but it can be removed by using something like Goof off.

Highly Effective-Just Be Prepared for Some Fly Remains!
If youâre tired of pesky flies invading your space, these transparent window fly paper sheets are a game-changer! They work incredibly well, discreetly blending into the window while trapping insects without the mess of traditional fly traps. The adhesive is strong enough to hold even larger flies, and the transparency keeps things looking clean until it’s time to replace them.The only minor downside? Well, they do their job too wellâmeaning youâll have fly corpses stuck to your window. Itâs a small price to pay for a fly-free home, though, and swapping out the sheets when they fill up is quick and easy.Overall, this product delivers exactly what it promisesâfantastic fly control with minimal fuss. Highly recommend for anyone wanting a simple yet effective solution!

Works amazingly well!
I loveeee these and flys are a huge problem during summer in south Texas, Iâve put these on many problem area windows and have barely seen flys. Stay on the window well, easy to peel off and do a really good job tracking Ive shared this product with a lot of friends and family.ALSO traps nats sometimes little spiders. Works way better than that stinky nat fluid traps
Nae P –
This thing is the best! It works.
This product is the read deal! I seriously have never used any indoor fly trap that worked as well as this one does. Itâs easy to place up, easy to take down and will catch ALL the flys. I put mine in the window corners and it gets them every time since they always seem to migrate to the windows. I rarely leave reviews but this thing is a quality product. I highly recommend.
Sarah –
Put up 5 on my windows where they were all hanging out, and within 6 hours I had already counted 30 of them caught!!! Haha yes!!!! It works great ðð¼ very satisfied. And they are easy to apply!
m wiggill –
This product works very well. I placed some at the bottom of the windows and some higher up on the windows.Day 1 – only about 3 flies caught – bottom of window strips onlyDay 2 – about 5 flies caught in total – bottom of window strips onlyDay 3 – about 9 flies caught in total – about 2 in the top window stripsDay 4 – about 20 flies caught in total – about 4 in the top window stripsDay 5 – many more caught.I did not even know there were so many flies in the house.Placing them horizontally near the bottom of the window worked very well. The ones higher up did not catch much

I get fruit fly sized bugs in Saudi but fruit fly traps donât seem to work. This is the only thing that seems to get rid of them and keep them under control. Easy to install and remove. 10 out of 10
Doreen Radom –
So much better than the long unsightly fly strips that hang down from the ceiling. Won’t use anything else now that I’ve found these. We live in an older home and we’ve found that these work very well. Some adhesive is left on the window but washes off easily. I’ve even used them in our camper. Easily attaches to the bathroom skylight and vents.

Easy to apply, the flies get stuck easily and also catches little bugs and anything that crawls onto it. Easy to peel off and you just throw them away when ready. This one has been on for four days. We have had a lot of flies and this means we can eat inside and not be bothered as within minutes they fly into them.
