This Device Didn’t Just Work—It Wiped Out My Fruit Fly Problem

After one too many evenings battling fruit flies in my kitchen, I decided to try the Katchy Duo Indoor Insect Trap. I figured it couldn’t hurt—but I wasn’t prepared for just how effective it would be. This little device didn’t just reduce the problem… it erased it. I’ve now bought multiples for other rooms, and the results are the same: they catch everything.

Look at all the fruit flies.

From the moment I plugged it in, Katchy went to work. The combination of 360° UV light and optional scent pod lures bugs in, and a quiet fan pulls them down onto a sticky glue board they can’t escape from. It’s strangely satisfying to check the trap and see dozens—sometimes hundreds—of fruit flies trapped inside.

What surprised me most was how quickly it worked. Within a day or two, I saw a huge difference. Within a week, I didn’t see a single fruit fly buzzing around. I ended up ordering a second one for the foyer and a third for the hallway by the plants. Each one made a noticeable difference almost immediately.

You don’t have to babysit this thing. There are five light/fan settings to choose from, and an automatic mode that kicks on when it gets dark—exactly when fruit flies come out. The glue boards are easy to change, and disposal is totally hands-free. Instead of buying the glue boards from Katchy, this generic 48 pack is cheaper and they’re practically just as effective and easy to change.

If you’re constantly swatting at gnats or fruit flies, just get one of these. Or better yet, get two. For me, the Katchy Duo wasn’t just a bug trap—it was a lifesaver. My kitchen is peaceful again, and I don’t dread reaching for the bananas.
