I’m standing in my kitchen, swatting at tiny pests buzzing around my sink, and I’m about to lose it. Fruit flies and drain flies—those annoying little invaders—have taken over, and I’m desperate for a solution.
That’s when I stumbled across Green Gobbler Fruit Fly Killer, and let me tell you, it’s a game-changer. If you’re battling these pesky flies, you need this product in your arsenal.
It’s easy to use, eco-friendly, and actually works. Trust me, you’ll want to grab a bottle before those flies turn your home into their playground.
My Battle with Fruit Flies and How Green Gobbler Saved the Day
Picture this: I walk into my kitchen one morning, ready to make coffee, and I’m greeted by a swarm of tiny black dots zipping around my sink. Fruit flies—or maybe drain flies, I wasn’t sure—had invaded my space. I tried everything: pouring boiling water down the drain, setting out vinegar traps, even cleaning every surface like a maniac.

Nothing worked. The flies kept coming back, mocking me with their persistence. I felt like I was living in a horror movie, except instead of zombies, it was these relentless pests.
Then I found Green Gobbler Fruit Fly Killer at my local hardware store. I was skeptical—after all, I’d been burned by other products that promised miracles but delivered nothing. But the reviews were promising, and I was desperate. So, I brought home a 32-ounce bottle and got to work.
The instructions were simple: pour 8 ounces down the drain at night, let it sit, and repeat daily until the flies are gone. I followed the directions religiously, coating the drain’s sides to ensure the gel clung to every surface.
The first night, I didn’t notice much difference, but I stuck with it. By day three, the number of flies had noticeably dropped. I’d see one or two stragglers instead of the usual dozen. By the end of the week, my kitchen was fly-free.
I couldn’t believe it. The gel’s thick formula, infused with citronella and cinnamon oils, had worked its magic, killing the flies and their larvae right in the drain. I even used it in my bathroom sink, where I suspected some flies were hiding, and it tackled that problem too.
What I loved most was how easy it was. No mixing, no complicated steps—just pour and wait. The scent was pleasant, not like the chemical stench of other drain cleaners. I also appreciated that it’s safe for pipes and septic systems, so I didn’t have to worry about damaging my plumbing.
My experience wasn’t perfect, though. I had to be patient and consistent, and I used most of the bottle over a week. But compared to the months of frustration I’d endured, it was worth every penny.
The Pros Of Green Gobbler Fruit Fly Killer
- Let’s talk about why Green Gobbler is worth your time and money. First off, it’s incredibly effective when used correctly. I saw a dramatic reduction in flies within days, and many users share similar stories. One person I read about had been battling sewer flies for months, trying everything from bleach to vinegar, but Green Gobbler wiped them out in a week. The key is its thick gel formula, which clings to drain walls, targeting flies and their larvae where they live. Unlike sprays or traps that only catch adult flies, this gets to the root of the problem.

- Another big win is its eco-friendly ingredients: The gel uses natural citronella and cinnamon oils, which repel flies without harsh chemicals. I felt good knowing I wasn’t pouring toxic sludge down my drain. It’s also safe for garbage disposals, septic systems, and all types of pipes, which gave me peace of mind. I didn’t have to stress about corroding my old cast-iron pipes or harming the environment.
- Ease of use is another huge plus: You just pour 8 ounces into the drain, ideally at night when the drain isn’t in use, and let it do its thing. No scrubbing, no mixing, no fuss. The bottle’s anti-glug design makes pouring a breeze, reducing spills. I also found the scent surprisingly pleasant—think lemongrass with a hint of spice, not the usual chemical burn you get from drain cleaners.
- Finally, it’s versatile: Whether you’re dealing with fruit flies in your kitchen, drain flies in your bathroom, or sewer flies in a commercial space, Green Gobbler handles it all. I used it in multiple drains around my house, and it worked consistently. For anyone running a restaurant or hotel, this is a lifesaver for keeping drains pest-free without calling an exterminator.

The Cons Of Green Gobbler Fruit Fly Killer
- No product is perfect, and Green Gobbler has its quirks: For starters, it’s not a one-and-done solution. You need to apply it daily for several days—sometimes up to a week—to fully eliminate an infestation. I used about three-quarters of a 32-ounce bottle over five days, which felt like a lot. If you’ve got a severe infestation or multiple drains, you might need to buy several bottles, and that can add up. At around $20-$30 per gallon, it’s not the cheapest option out there.

- Consistency is another challenge: If you skip a day or don’t clean your drains beforehand, the results can be disappointing. I learned this the hard way when I got lazy and missed a night—flies started creeping back. Some users also report that it doesn’t work if the flies aren’t coming from drains. If your infestation is from overripe fruit or dirty trash cans, you’ll need to address those sources first.
- The gel can also be messy if you’re not careful: I spilled a bit on my sink the first time, and it’s sticky enough to require some scrubbing to clean up. Wear gloves if you’re sensitive to citronella, as it can irritate skin. Lastly, while it’s effective for most, some users with stubborn infestations found it only reduced flies, not eliminated them. In those cases, combining it with other methods, like traps or professional help, might be necessary.
Tips For Keeping Your Drains Fly-Free:
- Regular Applications for Prevention: Once I got rid of the flies, I wasn’t about to let them come back. Green Gobbler recommends applying 4-8 ounces weekly as maintenance, and I’ve stuck to this routine. Every Sunday night, I pour a small amount down each drain, focusing on the kitchen and bathroom sinks. It takes two minutes, and it keeps my drains clean and fly-free. If you live in an older home or a humid climate, where flies are more common, this step is crucial.
- Clean Drains Before Treatment: Before using Green Gobbler, give your drains a good scrub. I use a drain brush to remove any gunk or buildup, then flush with hot water. This ensures the gel can cling to the pipe walls and work effectively. If your drains are clogged or full of debris, the gel might not reach the flies’ breeding grounds. A clean drain also helps you pinpoint whether the flies are actually coming from there or somewhere else, like a trash can.

- Seal Drains During Treatment: One trick that worked wonders was sealing my drains after pouring the gel. I’d cover the drain with a glass bowl or plastic wrap for 8-12 hours to trap the flies inside. This prevents them from escaping while the gel does its job. One user I read about swore by this method, saying it kept flies from spreading to other rooms. Just make sure to flush the drain with hot water after removing the cover to clear out any residue.
- Combine with Traps for Extra Power: While Green Gobbler tackles the source, pairing it with traps can speed things up. I set out a few TERRO fruit fly traps near my sink to catch any adult flies buzzing around. The traps lured them in with a vinegar-based bait, while the gel killed the larvae in the drain. This one-two punch cleared my infestation faster than using the gel alone. Just don’t rely on traps alone—they won’t solve the root problem.
- Monitor and Address Other Sources: Flies are sneaky, and they don’t always come from drains. I made sure to check for other breeding spots, like overripe fruit, damp sponges, or overflowing trash cans. Keeping your kitchen clean and dry is half the battle. I started taking out the trash daily and storing fruit in the fridge, which made a big difference. If you’re still seeing flies after treating your drains, do a thorough sweep of your home to rule out other culprits.
How Green Gobbler Stacks Up Against The Competition
- TERRO Fruit Fly Traps
TERRO’s traps are a popular choice for catching adult fruit flies, and I used them alongside Green Gobbler. They’re small, apple-shaped containers filled with a liquid bait that lures flies in, where they drown. They’re great for quick results—within a day, I saw dozens of flies trapped. However, they only target adult flies, not larvae, so they don’t address the source of an infestation. They’re also messier to dispose of, and you need to replace them every 45 days. Green Gobbler, on the other hand, gets to the root by killing larvae in drains, making it a more comprehensive solution.

- InVade Bio Drain Gel: InVade Bio Drain Gel is another drain treatment I came across in my research. Like Green Gobbler, it’s a thick gel that coats pipes to kill drain flies and their larvae. It uses microbes to break down organic buildup, which sounds impressive, but it’s pricier—often $30-$40 for a 32-ounce bottle. Some users, including one who battled gnats for a year, found it cleaned drains well but didn’t fully eliminate flies. Green Gobbler’s citronella-based formula seemed more effective for repelling flies long-term, and it’s generally more affordable.
- Aunt Fannie’s FlyPunch: Aunt Fannie’s FlyPunch is a kitchen-friendly trap that blends into your decor, looking like a spice jar. Its vinegar and fermented fruit bait attracts flies, and it’s super easy to use—just flip the lid and place it near the infestation. I considered it for my countertops, but it’s only effective for adult flies, not drain-based larvae. It’s also more expensive per use than Green Gobbler, and you’ll need to replace it frequently for ongoing infestations. Green Gobbler’s drain-focused approach makes it better for tackling the source directly.
- Drano Max Gel: Drano Max Gel is a heavy-duty drain cleaner some people use for fly infestations, but it’s not designed for this purpose. Its harsh chemicals can kill flies and clear clogs, but it’s not eco-friendly and can damage pipes over time. I steered clear after reading about its potential to harm septic systems. Green Gobbler, with its natural ingredients and fly-specific formula, is a safer bet for regular use. Plus, Drano doesn’t have the repellent properties of citronella, so flies are more likely to return.

Frequently Asked Questions (FAQ)
Yes, it works, but you need to be diligent. I saw a significant reduction in flies within three days and complete elimination after a week of daily use. The gel’s citronella and cinnamon oils kill flies and repel new ones, while its thick formula targets larvae in drains. However, you must clean drains first and apply it consistently. Some users with severe infestations needed multiple bottles or complementary traps, but for most, it’s highly effective when used as directed.
It’s tough to crown one product as the absolute best, but Green Gobbler is a top contender for drain-based fruit fly infestations. Its ability to kill both adult flies and larvae sets it apart from traps like TERRO or Aunt Fannie’s, which only target adults. For overall effectiveness, combining Green Gobbler with a trap like TERRO might be the ultimate solution, as it tackles both the source and stray flies. User reviews consistently praise Green Gobbler for its results.
The most effective solution combines drain treatment with traps and good hygiene. Green Gobbler excels at killing flies in drains, where they often breed, but you’ll get faster results by pairing it with traps like TERRO or KATCHY to catch adults. I also recommend cleaning drains, sealing them during treatment, and eliminating other attractants like overripe fruit. This multi-pronged approach stopped my infestation in its tracks, and many users report similar success.
Green Gobbler is one of the most effective drain fly killers I’ve come across. Its gel formula clings to pipes, killing flies and larvae with natural ingredients like citronella. Compared to InVade Bio Drain Gel, it’s more affordable and has better repellent properties. Some users combine it with Gentrol IGR for stubborn infestations to target larvae specifically. For best results, apply it daily for a week and maintain weekly treatments to keep drains fly-free.
Final Thoughts
