Over the years, I’ve tested countless pest control solutions—sprays, sticky strips, ultrasonic devices, and homemade vinegar traps. Most of them were either messy, smelly, or simply didn’t work. When I first heard about the Zevo Flying Insect Trap, I was skeptical. Could a plug-in light really solve my fruit fly and gnat problem? I decided to find out for myself. I bought the starter kit and a four-pack of refill cartridges, and I’ve been using them for months. I’ve tested them in my kitchen, bathroom, and near my houseplants. I’ve seen what they catch and what they miss. Now I’m ready to share my honest experience—so you can decide if these refills are worth your money.
The Good and The Bad
Buy this product from Amazon
What I Liked:
- Works fast – Within hours of replacing a cartridge, I noticed a visible reduction in flying insects, especially fruit flies and gnats. One reviewer caught 36 bugs on the first night.
- Incredibly sticky – The adhesive panels are very sticky. Once bugs land on them, they’re not going anywhere.
- Mess-free disposal – You never have to touch the dead bugs. Just pull out the cartridge and throw it away.
- No odor – Unlike sprays or vinegar traps, these refills have no added fragrance or chemical smell.
- Safe around kids and pets – When used as directed, they’re safe for households with children and pets.
- Easy to replace – Installation takes just seconds. Slide the cartridge in, peel off the protective film, and you’re done.
- Discreet design – The trap looks like a normal plug-in air freshener. Guests won’t even notice it.
- Works 24/7 – The trap keeps catching bugs day and night.
What Could Be Better:
- Expensive over time – Refills cost about $3.74 each. If you live in a high-bug area or have many houseplants, you might need to replace them every 2-3 weeks.
- Best for small insects – Works great for gnats and fruit flies, but not as effective for larger house flies.
- Limited coverage – Each trap covers a small area. You might need multiple traps for larger spaces.
- Bright at night – The blue light can be bright in a dark room. Some users unplug them before bed.
- Not a standalone solution – The trap catches bugs but doesn’t eliminate the source. You still need to address overripe fruit or damp potting soil.
- Third-party alternatives exist – Some users find cheaper off-brand refills that work almost as well.

Who Should Buy This Product
If you’re dealing with fruit flies, gnats, or other small flying insects in your home, these refills are for you. They’re perfect for kitchens where fruit flies gather, for plant-filled rooms where fungus gnats thrive, and for bathrooms where drain flies appear. They’re also great for anyone who wants a clean, discreet pest control solution—no sprays, no sticky strips hanging in plain sight.
If you’re like me, you want something that works without being ugly or smelly. These refills deliver exactly that.
However, if you’re dealing with large house flies or mosquitoes, this might not be your best option. Also, if you’re on a tight budget, the ongoing cost of refills might add up quickly. Some users prefer cheaper alternatives like homemade vinegar traps.

My Experience with Zevo Refill Cartridges
The First Week – I Was Shocked
I’ll be honest—I didn’t expect much. I’d tried those little apple-shaped fruit fly traps before, and they barely caught anything. But within the first few days of using the Zevo trap with a fresh refill cartridge, I saw a difference.
The cartridge started collecting tiny bugs almost immediately. Every day, I’d check it and find more gnats and fruit flies stuck to the adhesive. It was gross but satisfying. One reviewer said they caught 36 bugs on the first night with two traps running. I believe it.
What surprised me most was what the trap caught. I thought I only had a few fruit flies. But the cartridge showed me there were way more flying around than I realized. The trap was doing its job quietly in the background.

How Long Do They Last?
This depends on how bad your bug problem is. In my kitchen, a cartridge lasts about 3-4 weeks. But if you have lots of houseplants or live in a high-bug area, you might need to replace them every 2-3 weeks.
One thing to watch for: dust can settle on the adhesive over time, making it less sticky. Even if the cartridge isn’t full of bugs, it might be worth replacing after a month to keep the trap working at its best.
The Sticky Factor – Very Sticky
When I first touched the adhesive on a new cartridge, I was impressed. It’s incredibly sticky. Once a bug lands on it, there’s no escape. The adhesive stays strong throughout the cartridge’s life.
This is a huge improvement over hanging fly strips, which lose their stickiness quickly and look terrible. The Zevo cartridge keeps everything hidden and contained.
Replacement – So Easy
Replacing a cartridge couldn’t be simpler. Here’s how it works:
- Pull the used cartridge straight up and out of the device.
- Drop it in the trash. No mess, no touching dead bugs.
- Take a new cartridge and slide it into the device.
- Peel off the protective backing where it says “pull here.”
- Plug the device back in.
That’s it. It takes about 30 seconds. The blue light tells you it’s working. If the light blinks, it’s a signal to check the cartridge.

Performance – What It Catches and What It Misses
What it catches well: Fruit flies, gnats, midges, and other small flying insects. One user said they also caught moths and mosquitoes.
What it doesn’t catch as well: Larger house flies. Some users say it catches a few, but it’s not as effective for bigger bugs.
Pro tip from experienced users: Turn off all other lights in the room at night. The blue Zevo light attracts bugs much better when it’s the only light source. One reviewer said they caught twice as many flies after darkening the room.

The Cost – Worth It or Not?
At about $3.74 per cartridge, the cost adds up if you need to replace them frequently. Some users find this expensive, especially since the cartridge is essentially just “sticky cellophane”.
That said, many users find the convenience worth the price. One reviewer said the refills are “a great value for the money” and the most reliable option they’ve used.
If you want to save money, there are third-party refills available at nearly half the price. However, they might not work as well as the official Zevo cartridges.
Zevo Refills VS Other Options

My take: If you want the cleanest, most effective solution for gnats and fruit flies, the Zevo system with official refills is hard to beat. It works, it’s discreet, and it’s safe. Yes, it costs more than homemade traps. But for me, the convenience and effectiveness are worth it.

Common Questions
How long does each refill last?
About 3-4 weeks, depending on how many bugs are in your home. In high-bug areas, you might need to replace them every 2-3 weeks.
Can I use off-brand refills?
Yes, there are third-party refills available. Some users say they work nearly as well. However, the official Zevo refills are designed specifically for the device and may perform better.
Do these work for mosquitoes?
Some users have caught mosquitoes in the trap, but they’re not the primary target. The trap is best for gnats, fruit flies, and small flying insects.
Are they safe around pets?
Yes, when used as directed. There are no chemicals or odors. The trap uses light to attract bugs and a sticky cartridge to trap them.
How do I know when to replace the cartridge?
Check the cartridge regularly by pulling up on the tab. If it’s full of bugs or dusty, replace it. The blue light will also blink to signal that you should check the cartridge.
