The BEST Fungus Gnat Killer [Actually Works!] 5 Yrs Gnat-Free and Counting! 

I gave up on plants and became a full time gnats farmer

I had a huge "cake party". Every gnat family was invited. Even with such a successful event I haven't heard much from my guests since. Lol! You saved my young plants. Thank you.

I knew you were legit when you listed like 12 ways to kill gnats 😂 Thx

"It's just beautiful knowing that they are experiencing a slow and tricky and strange death to their entire population." LOVE THAT LINE.

I tried it and after one application the gnat population dropped dramatically. A week later I did it again and the population has dropped down to under 5%. No exaggeration. Best thing I've ever tried, hands down. Thanks 👍

I followed his instructions and had a pretty severe infestation a few weeks ago after five days with a couple of soil drenches.. it all cleared up.. fantastic

I would personally like to thank you. I have been having a big gnat problem in my office. It looked like they were continuously flying past my face as if they were mocking me. I used sprays, bug bombs and everything I could think of to get rid of them with no success. I could not find the source of it anywhere. I finally came across your video and immediately realized what the problem was. I bought a big bag of potting soil a few months ago. It had a tear in the bag but I figured I was going to be using it soon so what's the difference. I wound up not using but instead, I put it in my storage room. As soon as I saw your video, I immediately ran back to the bag. I saw the gnats hanging out by that opening. I threw it out and set up bug bombs shortly after. This is the first day I was gnat free in months. Again...thank you!

Thank you so much, I am going to try the Neem Cake... Let's all invite the buggers to a Neem Cake Party!

Hydrogen peroxide didn’t work on any of my plants. Glad I found this.

Thank you so much I feel my house is being taken over by these stupid things, like as if I am living in the days of Egypt with the plague of the flies! I have tried Vinegar & the sticky traps....I can't tell u how much I needed this, thank u, thank u, thank u!

Zevo Insect Trap that plugs into an electrical outlet is the bomb. The blue light attracts bug, then get stuck on the sticky back. Plus you don't have to look at the trapped insects.

Dried neem leaves also work VERY well against yeast in a dog. I had a dog who had severe yeast issues. She had itchy skin, crusty ears, and it got to the point where she also didn't absorb the nutrients in her food as well. (Her colon made a biofilm to protect itself against the yeast which blocked a lot of the nutrients from going through.) I tried so many things, none of which worked. Then I finally tried dried neem leaves added to her food. Within a week I noticed a big difference, and in two weeks the difference was like night and day. She felt so much better! After about three weeks her ears stopped being crusty, her coat became shiny and full again, and I actually had to cut down on her food because she was absorbing the nutrients so well again that she was gaining too much weight. Neem is absolutely amazing! It is very bitter, but I think dogs don't taste bitter because I give all of them neem now (can't hurt, I'm sure) and they all eat the food right up.

Thanks so much. Here in Arizona gnats are everywhere and everyone is having trouble. I received my bag of Neem cake from Florida Garden revival in 3 days. On Saturday I watered everything houseplants and vegetables. Today is day 4 and there aren't many left except of course the smell. I'm looking forward to a gnat free life.

Awesome video Evan. I really enjoy your presentation, and the solutions you have from your experiences. YOU ARE your father in all things green thumb!

That greenhouse is so lovely.

Can’t wait to try this! My Welsh Terrier patrols the whole house huffing like a lion whilst hunting down fungus gnats. They drive both of us nuts!

Thank you. I loose all my house plants. i had them in my closet my bed. my draw they eat and drink with me, they live with me for about five years. i use every thing they say will help. but they are the strongest i have ever seen. so this summer i spray the house and every other day i might see one. for the last time i will buy the neem cake. thanks

Soooo glad to finally find out how to stop gnats... they drive me crazy. Thank you so much!

What a life savor your information is! Thank you!

Thank you for this info. I had gnats in my kitchen in NE Florida last week because of an infestation in a kale plant I recently bought and didn’t replant right away.

I can't thank you enough. I have used this method over the last two years and it is legit. I still have not used up the whole bag yet. I only use it every other watering and I keep using it even after it rots, because the smell in the greenhouse goes away quickly and it still seems to work. I use fish fertilizer so I am used to awful smells in the greenhouse anyway. 😛

For anyone with extra neem oil otherwise intended for the garden: neem oil is also useful for scars.

I've been fighting gnats for awhile. Definitely will try this. 3 heaping tablespoons per gallon of water. Let steep for a few hours until the water is brown. Use for watering and flood the surface of the soil. THANKS

I'm SUPER excited to try this! We have a significant gnat problem at our new home and summer is looming. I'm also putting in a large garden so my fears are deer, rabbits, armadillos and GNATS. I've got the bigger critters beat but this should give me the edge I need to have a successful garden. Thank you!

I've been battling gnats for what felt like forever, and nothing seemed to help. Then I tried your suggestion, and bam, three weeks later, they're all gone. Vanished for good. Thanks brother!

Holy cow I’ve never heard of this! Thank you! I used nematodes and they totally eradicated the gnats-but they’re slowly making a comeback.

I’ve tried EVERYTHING!!!! Need to try this

Never heard of the neem cake. Def worth a try. I have had 100% success with nematodes mixed in the water. They're little beneficial bugs that eat all the gnat eggs and larvae. Thanks for the video 😊

This is the best gnat control I've ever used. Thank you so much.

100% concur, neem cake works miracles ! I mix it sparingly with my plant starter mix. The mix gets moistened and potted up, so the neem cake breaks down over time.

After trying every technique on the internet. This was the only one that actually worked!!! Thanks!

This works and I've incorporated into my watering routine Thank you for posting. I've bookmarked this video into my 'reference' library!

Neem meal and proper bottom watering practices both help immensely. Especially coupled with those nasty fly strips lol

Thanks for sharing this Awesome information 🤩 I've been using neem cake for years and its working great!

Wow just wow, I’m sitting here with these little buggers buzzing me. I’m so glad I came across your channel. I surly hope this is the remedy. Thank you 😊

Thank you soo much and also to all the folks in the comment section that also have tried it and posted. I've tried almost everything also, including the Neem oil. I'm off to find the Need cake.😉Wow, that was easy to find. Thanks again!

Thank you so much. This really worked on my gnat infestation.

Thank you so much for this!!!! My plants were getting taken over by the fungus gnats and were looking sickly and yellow, within 2 days of treating them with the neem cake they are literally on a second life. They’re green, full, healthy, growing and most importantly, I’ve seen very very few gnats in the past couple days! Thank you so much this really helped saved my plants lives

Love your video straight to the point. No haggle no nonsense 😂😂❤

Thanks dude. I've tried over half of your list at the beginning of the video. I'm hoping this works for me

live in Bedford, TX. and my houseplants were terribly infected - used top gravel, Mosquito bites (works pretty good), sticky yellow things, and an electric Zevo light - grr, STILL have them, fewer, bit STILL - DEFINATELY trying this!! THANK 😊 YOU;)

A good Homemade sprinkler for solutions like this is a Gatorade style bottle with small nail holes punched in the lid. It saves me from rinsing my regular watering can, and I can reuse it as many times as I need or throw it away, for that single solution.

just watched this video and bought the neem cake. Trying when it comes through amazon tomorrow. Will come back to this video when it HOPEFULLY works

Thank you Just ordered some got it today from Amazon!! Hopefully I'll be fungus nap free here in the next week or so! Thank you so much!!!

i tried all the things he listed and had similar results. this actually works and the plants seem to love it. i top the soil with the neem pellets and water with the tea. i love the smell, like fertile earth after rain. first time gnat free and loving it, thank you sir!

THANK YOU! I had a major fungus gnat issue with multiple plants in my home and this has solved it (and I had tried so many other options).

Thank you sir! had my doubts, but it works. 👏🏽 👏🏽 👏🏽 👏🏽

Word! Been using neem cake for soil amendments and have noticed a lot less bugs in addition to fungus gnats. Using neem cake to make a tea and soil drench sounds even better. Thanks for sharing! :D

Last autumn I brought my family of kalenchoe's indoors to save them from the expected freeze. Yes, the plants were saved but not long aferwards I discovered the little gnats were also enjoying my indoor shelter. Thankfully, your video has given me a good tip which I shall try and hopefully get rid of the little blighters in the not too distant. Thank you for this advice.

So i bought a peace lily off of craigslist (someone was selling their plant collection cause they were moving) and this thing brought fungus gnats home that ive been warring with for like 6 months now. Ive tried everything. Sticky traps, neem oil, repotting everything, forced drought, literally raid insecticide, topsoil covering, i just wanted these things gone. Heres what finally worked, a fan, sticky traps, AND THIS. THE NEEM MEAL IS THE SECRET SAUCE. I havent seen a gnat in a week and will update if the infestations gone gone in a few weeks. The fan i have blowing on all of my small plants i can move so any straggler adults cant fly to them, and i have sticky traps in the soil of my big/sensative plants. The neem meal watering seems to be working super well and any adults that make their way to the plants that dont have fan protection get caught in the sticky traps. Took a week to see a substantial difference but im two weeks in now and can see zero activity in my plants soil. Going to give it a few more weeks before the final all clear incase any larvae are hiding anywhere, but if youve been struggling the way i have with gnats, please give the neem meal a try its magical

This stuff actually did work for me after 2 treatments. Didn’t seem as though it would for some time, but no gnats for months now. I also used a potting soil from Miracle Grow that’s designed to discourage gnats. Thanks so much Luke

lool I can tell from the commment at the end that you've been through trial and tribulation with the winged nightmare that is the fungus gnat. Will definitely give this a try myself, thanks mate!

This couldn’t have come at a better time… literally trying peroxide/water for eggs and vinegar/water for gnats. If this works (Neem cake) it will be a great help. Thank you, 😊

Many thanks. I'd live in that greenhouse happily, wow! Being in a bachelor pad, 40 plants and counting... well, it's trippy. No, there are no plants near the stove, though I've propogated some dischidiae in the drying area for dishes. Hmm. You must be thrilled with that fabulous garden!💐

I will definitely be trying this!

Thanks I have just ordered some neem cake, I look forward to being gnat free, at last! 😀

umm okay, first of all: Insta sub!, 2nd: wow amazing fig growth love it and I'm inspired to grow one in my living room with my scary-strong LED light: 3rd: love LOOVE that you kept in mind the ecosystem of the soil, that's what I was worried about. 4th: that evil smile you gave at 5:17 was priceless. and 5th: omg please come to Austin and help me with my little indoor grow set up! haha

Good info, thanks. Also want to share what works for me 100% of the time. Start with sterile potting mix. Can also sterilize soil mix with 2-3 min in microwave. I have a silicone pan dedicated for this purpose. Great to prevent damping off disease in seedlings too.

I got rid of the fungus gnats along with the soil they were in! But, happy to see there would have been a way to handle them!

Ohhh MYY gosh!!! I cannot believe u just popped up n my feed bc last spring up until it got really cold here in Vegas I’ve had problems! I mean so bad that I had to throw my plants and the soil away 3 times last year ! And just the other day I started seeing some adults All over again ! And I did all those things you talked about and my own. Im going to purchase asap ! I also had an issue with idk if it was a worm or what but it was so tiny and it would make the stems LOOKY scaly and then started eating the inside of my plants ! Oh my gosh I don’t want them back ! I grew up on a farm in Oregon and we never had these particular problems! And made the stems like all skinny , dried out looking but the higher the stems went they were ( actually are bc I have tomato plants still growing and producing tomatoes ! I DIYd my own lil greenhouse on my condos porch !! ) so ya my tomato plants ( some) are skinny and dry looking at the bottom towards the root like a foot upward and then it looks normal . I think that’s bc the bugs didn’t get that far . But now I’m wondering if I should pull them before I plant again even tho tomatoes are growing bc maybe they hibernated and when it warms up they will b back . Idk bc idk what kind of bug I’m dealing with ! And yes! The oil form stinks sooo badly I can’t stand it!

Thank you so much for this. First winter with my houseplants being infested as bad as ever. About to use mosquito dunks but will order the neem cake instead. Thank you

I use an inch or two of sand on top of the soil, never have gnats or spider mites. Also, a small USB fan blowing across the soil level of my set up. If I am bringing plants in for the winter, they get soaked three times with insect soap.The stems and leaves get wiped down, hit with some neem oil, and I'm pretty much done. Then sand on top. I bottom water most of my stuff.

After finding this video, I realized what was floating in hundreds were gnats. I've been having scooping these up for a few weeks now and wondered where they came from. I'm hoping by spraying this neem cake mix all over the backyard garden that it will help get rid of these tiny pest, bc it's driving me up the wall cleaning them out from my pool every day. Thank you for sharing this valuable tip!!

I see your background and instantly trust you

Will add this to the arsenal. I had a bad infestation in my atrium earlier this year, and I wiped them out over a few days with no ill effects. Method? 1. Cut some thick plastic sheet to go around the circumference of the pots to be treated. Maybe a 2+ foot wide strip. 2. Tape to pot (I used cutout tape since it leaves no marks). The goal is a skirt that rises ABOVE the lip of the pot as tall as possible. I tape the lower edge... imagine you're trying to fill the pot above the lip by 1-2 feet. 3. Go to grocery store and buy dry ice. A decent amount (a few pounds?) 4. Put some bowls/pitchers/whatever in the planter where they fit with hot/warm water. 5. Add dry ice to bowls. Skirt will fill with the CO2 mist. You'll need to periodically change the water to keep the gas attack going. I tried to keep them in a CO2 rich environment for about an hour. I tested with candles, they'd extinguish quickly within the inverted skirt. Bugs? Yeah, they need oxygen, so this kills all of them. Plants? They love CO2, so yay. I did this waited a few days, did it again, then waited a week or two, then did it one more time. Have seen zero flies since then. Put some of those yellow sticky traps out before and after. before they were black in a day, after I threw them out clean. The method in this video would probably be awesome combined with the CO2 attack.

I just had a major houseplant shopping spree and unfortunately reintroduced fungus gnats into my home. I got rid of them in the past by using 1 part hydrogen peroxide 3% to 4 parts water. I had to water my plants religiously with this for a few months. One thing I noticed was as I was preparing some yogurt to eat during the past infestation of gnats, 3 gnats immediately landed on my yogurt...yuck. They must be drawn to the microbes in the yogurt. Anyway thank you for sharing this. I would much rather use this method to get rid of them because buying countless bottles of peroxide is a pain and this method is very appealing and may not take as long to get results

I'm going to try this. I've tried a few other things... I literally vacuum them on the window lol. Thank you :)

My neem cake arrived today, I can't wait to get rid of those irritating buggers

Thank you! These things killed off all that was starting & growing in my little greenhouse 3y ago which really put a damper on my growing. We grow in containers on our deck. Last year I didn't have them. This year they are full blown infestation! Putting an order in for mosquito bites & some other natural things to help eradicate them.

Neem Cakes are very common and ridiculously cheap (like $2-4 for a big 5Kg pack) here in India. We usually get them in grounds which I directly add into my potting mix but I'll try this tea method as well. Thanks

Yeah, I will put this is the ole' memory banks for what to do next, should I need. I used the premixed neem oil from the garden center and it seems to be working. It takes awhile for adults to die off, and I am seeing less and less. God love 'ya for sharing this.

Thank you for sharing! I have tried so many treatments but nothing really works. I am going to order this and try it out.

7 years fighting with those nasty gnats, lost my gardenia, list over 40 figs, and after i saw this video i decided this is my last battle, thanks for sharing the video and thanks to the one who referred us to the one who sells them neems in Ontario. Best wishes for all.

Well folks, I have a unique problem with these fungus gnats. I have a GREENSTALK 6 tier plant tower (which is great!!) that is planted with herbs, veggies and seeds. Seems one of my bags of dirt must have had these stinkers in it. I've aerated the soil a bit. Problem is that it's hard for this to really dry out as the air can't get to the middle area of each section where the water tray sits. Hmmm .... I may try to separate them for a day to aid in that process. I have my NEEMORGANICS Orgo Neem Cake all mixed up in 2 - 2 quart glass jars and will let it set for a while and water the tower tomorrow or the next day. I'll keep you posted. Wish me luck!!

Thank you and your plants are amazing

thanks definitely going to try that for gnats and mealies too.

Never heard of neem cakes. Very interesting. I have complete success with 3% peroxide though. I spray it or drench infected soil straight up and they are gone in 48 hours. The plants seem to love it too. It's usually easy to buy and super cheap. Except during covid. I couldn't find it for months and the gnats were taking over. Could have used this info back then.

I’ve just received my Neem Cake in the mail and definitely will let you know how it goes 🙂 I’ve tried everything and was going to transplant my indoor plants to Leca balls until I watched this video. Thank you so much for sharing 🙂

So glad to find this because I was using mosquito bait in a solution and it poisson.

ive tried alot, on some bad numbers of gnats, this worked pretty well, quality of neem plays a big part so watch for that. the only other thing to eradicate them are predatory nematodes.thanks for the vid

I had a lot of these fungus gnats, and tried a few things that didn’t really work. I did the mosquito pellet tea, and it didn’t seem to do much at first. I then figured I needed to trap adults, so I put out a bowl with a dab of maple syrup, dawn dish soap and water, and it attracted the little buggers like crazy. I think the maple syrup did the trick there (it was 100% maple); sugar didn’t attract them as much in my experience. I’d put out a bowl in the middle of my plants, and overnight there’d be a dozen or so. After a few days, there were scads, and I only had 7 plants at that point. But though using the “tea” along side the syrup mix seemed to be controlling them,after some time (months) it wasn’t lessoning the fact that gnats were still around. Then we went on a two week vacation. My plants (even the peace plant) survived as they were mostly succulents. But what didn’t survive the drought were the fungus gnats! I think the triple threat finally did them in. I haven’t seen one since. I have to repot a few of my younger plants, and I’m worried I’ll get gnat hitchhikers in the new soil, so I’ll be checking out how to sterilize soil BEFORE it becomes an issue lol. (ETA: I’ll definitely try the neem pellets if I get gnats again, as the mosquito tea controlled the amount of gnats but didn’t kill them off. I want total destruction of my gnat colony!)

What brand of neem cake are you using and where do I purchase it?

Thanks! I will try if needed, but so far, this mosquito bit tea has worked!

Thank you I will try your method 👍🏼

Thank you. This is the first year my DIY Neem oil solution, hydrogen peroxide, cinnamon and other remedies are not working. These are stubborn Fungus gnats I got from a plant I bought. I did quarantine this plant along with 7 plants. It took one plant to be invested with these huge gnats. I replanted 5 of them with new soil. Turns out made it worse the soil from Lowes had gnats too. I feel like I can't win. Four of my plants have died in one week. I always bottom feed so its not over watering issue. So leading up to your tutorial I just got my amazon package with my Neem Cake from "Neem Organics." I'm using an old gallon pickle jar with your recommendations of 3 Tablespoons of Neem Cake. Waiting until 6 hours letting it sit outside in the sun to get dark. I hope this works.

A cool side benefit of this is the infusion of protozoa you can get if you let it steep the right amount of time. It can be tricky without a microscope though as you risk the proliferation of ciliates as the tea goes lower and lower on oxygen. Basically the neem cake, unless it is sterilized when processed, comes loaded with bacteria cultures as well as the protozoa that consume them. Gives a big bump to your nutrient cycling :)

Thankyou. I like the idea of benefiting the soil as well.😊

Excited to hear another option I just bought nematodes and if they do not work, I will be buying neem cake. The smell is bad. I will also buy a nice candle.

Mosquito dunks always worked for me in my container plants. Always good to learn of other products/options

Thanks for the tip! Definitely going to try this because these little bastards have cost me literal-months of wasted time and 100% loss of yields.

Wiped them out like a boss. Couldn't be any easier. Thank you from the bottom of my heart. Thank you, thank you , Thank you!!!!

So glad to see that this is working for so many! In case interested, we did an accompanying 5-minute video on the use of this amazing natural insecticide for other common pests, along with some how-to tips and more elaboration here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eY3znjzP0kc.html Also, a video on the recycled window greenhouse: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gjRjfKehKIo.html

What would you suggest for infested raised beds? I have 5 beds but only 2 are infested. They are 2’X12’ and they are 17” tall.

great tip! I've used neem before but it's been years! Thanks I KNOW this will work! cheers!

Nice work from the land down under.🇦🇺 🤟

I was going to opt for BTI over Neem purely bc of the vile smell which I could not handle in my tiny apartment. Would you say the smell of the cake/pellets is much less potent than the oil? And does the smell dissipate fairly quickly? Also, all my plants are watered at different times. How long is the tea solution good for? (sans the neem bits)

Thanks you for the video! Just did my first watering with neem tea solution. Two questions: 1) besides smell, is there any detrimental downside to letting neem cake soak for longer, even as long as 24 hours? I was considering letting it soak that long and then diluting it prior to watering. 2) do you reuse neem cake pellets for another soak, or is there any additional use we can get from used neem cake?

Im so glad i found this video, thak you sm

Decorative Gravel, helps add a protective layer as well.

Do you know if the neem cake treatment will change the ph of the soil?
