Some additional things I've tried that seem to help a lot: (1) a small oscillating fan makes it tough for fungus gnats to get around, dries out the top of the soil faster, and helps strengthen stems. (2) a watering schedule (ideally with weighing pots if you have a lot of the same type), usually 5 to 7 days for 2.5" to 3.5" pots; and (3) yellow sticky traps, they can catch a fair percentage of the adults, but are even more useful for monitoring for fungus gnats and figure out where they are or are coming from.

Sticky traps & watering with Gnatrol has worked best for me. I’ve also used the sand as well & that helps too.

@amiegamble1678 5 месяцев назад

Mosquito bits for soil. Dunks for water. I have container pots outside that would have issues when it was the rainy season. I sprinkle this per direction. No more issues. Safe for us too.

@gelwood99 5 месяцев назад

YES! It is organic and a different strain of Bt, the organic control for catapellers especially attacking brassicas. I dissolve them in warm water and water my plants with it, this way uses less dunks with the same results.

@wess4664 5 месяцев назад

Good to see someone mention the mosquito bits. I've used the bits for years. Whenever I start seeds indoors I'll sprinkle some bits on the soil surface (or mix them in) and give it a good watering. It's rare that I'll see a gnat in the grow room these days.

@MarysGardenShed 5 месяцев назад

The dunks are a life saver- and they're pet safe. We use it in the chicken waterer.

@primitivedaisy 5 месяцев назад

Yeah, I use the bits, but it’s not the best. There’s also hydrogen peroxide in the water, and beneficial nematodes, and I’ve tried them all. A year later, there’s less, but they’re still here. There’s no one clear answer.

@JackB-ch2ny 5 месяцев назад

The only way I found to work was to microwave the soil before I pot AND once potted, cover the top 1 inch of soil with all purpose sand mix. Peroxide didn't work.

@Boosted0ne 5 месяцев назад

Sticky traps and Mosquito Bits soaked in water works well. Water in as directed on instructions. It might take a while to break the cycle but Mosquito bits/sticky traps works well for me. If you have them bad don't expect to just eradicate them overnite.

@CoffeeCakeCrumble 5 месяцев назад

I had a horrible herd of gnats that were sooooo obnoxious!! They'd purposely flitter right in front of my face, landing my coffee🤨 They enjoyed the ACV swimming pool....until they fell in. Game Over! Another tidbit is since I've had the fan running on the plants nonstop to keep the air circulating in the closet, their numbers have dramatically reduced to barely perceptible. They don't like wind🌬🌬🪰

@CherrieMcKenzie 5 месяцев назад

It took me awhile to realize I was over watering but once I provided more ground mulch to retain water and stopped watering as often the gnats went away. But thank you for these extra measures.

@jackiegoodrich1351 Месяц назад

I hung bug zapper lites near my plants. The zaps started right away! I smiled! Left them up for 2 months, was not hearing any more zaps, took them down, no gnats for over a year now! Dont forget to empty the dead ones out of the bottom trays! Good Luck! Rev. J. 😊

@JoyfullyOrangeDeborah 5 месяцев назад

I've had fungus gnats kill so many of my plants over the years and never knew what they were for the longest time, then I couldn't find a good way to get rid of them. Last time I got them from an herb plant i bought at the grocery store (i thought it being in the store it would be clean). I really appreciate this video Luke! Many Blessings from Deborah in West Virginia!

@tzarvladimir2987 5 месяцев назад

I would add that to you ideally want to combine multiple methods. For me it was a mosquito dunks and nematodes in the water. I'd start with but letting the tap water sit out for a couple days to dechlorinate and then add 1/8th of a dunk, leaving it for a couple more days. once the water had the right smell (kinda fruity), I would remove the dunk and just before I watered, I'd add the nematode bag. Usually got a few uses out of each dunk piece. I'm less convinced on the nematodes, but they were part of stopping the invasion. I continue to apply water with mosquito dunks as a preventative measure, along with good watering habits.

@LisaPebble 5 месяцев назад

Luke, you should have mentioned BTI, bacillus thuringiensis israelensis, mosquito dunk or bits. It doesn't smell like neem oil will and it is the ONLY thing I personally have found to be 100% effective. The sand on the soil definitely helps prevent them but so does bottom watering and also not overwattering. I put the dunk, usually broken into quarters, in a gallon of water let sit a couple hours and use it to water from the top where the larva predominately are located. I can refill the bottle many times before it starts breaking down and needs a new one. I have not had any problems since I've been using it. I also sterilize my soil using the boiling water rehydration method you suggested. Between those two things no gnats here! BTW, tried neem, stunk up the house and really didn't work that great, for me anyway.

I bought an electric kettle to sterilize my mix. Many brands are 1.7 litter. Happens to be perfect amount for 72 cell, 10x20 seed starting tray. When potting up use dry mix, then bottom water. 1.7 litters again in 10x20 tray. Approx 15-18 4" pots fit in tray. Top of soil will stay dry, preventing conditions favorable for fungus knats and algae/mold.

@79PoisonBreaker 5 месяцев назад

sticky traps help control adults from spreading. You overlooked the fungus gnats also lay eggs from the drainage holes under pots. bottom watering also helps. I use DE (Diatomaceous Earth) same as sand layer. Neem oil kills lots of good with the bad so I rarely use it unless a problem has gotten out of control.

@MarigoldsintheGarden 5 месяцев назад

I also have found that placing yellow sticky paper around the seed punnets helps with catching quite a few of the fly gnats. You can put small fish tank pebbles around the tops of the soil once your seeds have fully germinated into plants.

The struggle is real. I’ve been fighting them since before two Thanksgivings. We had a ton of rain the really warm weather. We were getting our floors done and the workers needed the door open. One guy was in our small bedroom that doesn’t have a screen. And we didn’t know he had the window open and the light was on. When they left there were hundreds oh them everywhere and of course groups in the wall near the light. After trying many things I got yellow sticky traps, mosquito bits and a bug zapper. I finally have it down to only the plants in my room. And I’ve almost one the battle🤦‍♀️ I will be adding some sand too🙌🏻

OH MY GOSH!! You have NO IDEA how wonderful stumbling across this video has been!! I literally have been seeing these tiny little black fly type gnats. I got some potted indoor plants from my niece for Christmas. I figured out they were coming from them. I didn’t have a clue what they were. Fungus gnats. Ha! Who knew! I didn’t know what to do about them because it was before finding this video and I didn’t know what a fungus gnat was. So I treated each of my spiked plants with a mixture of assorted essential oils and that seem to help tremendously. Thank you so much for sharing this!!

@lindaannb 5 месяцев назад

After repeated infestation with fungus gnats in my orchids, I bake all potting soil and orchid bark that I bring into my house. Orchids in bark are especially hard to treat. The gnats can live in all of the gaps between the bark pieces and don’t have to come to the surface. Gnatrol, together with sticky traps, kept the numbers low but to eliminate them all, I had to treat with an insecticide, too.

@rodneywelch3556 5 месяцев назад

@historyandhorseplaying7374 4 месяца назад

You didn't mention the most effective preventive measure I've found so far as a new grower-- moving air (i.e. overhead household fan on a high setting, or a cheap oscillating fan etc). Fungus gnats are bad fliers and are unable to penetrate the wall of moving air to even get to the plants, much less be able to land on them in the wind. Not practical for a large operation, but works for a small group of plants in a room with a regular overhead household fan on a HIGH setting.

@santa4me2 2 месяца назад

Great vid man.. I use Neem cake instead of Neem oil (Crushed seed).. Easier to disolve in water or soak, you can dump it on the top of the soil (Kills gnats and fertilizes the plants). I like neem oil for foliar spraying if i have insect problems.. Try neem cake with gnats 😀

Just 10 days ago I planted my Hosta seeds. They were topped with the fine vermculite, watered in and put on a heat mat. The flats had the clear covers on them. Three days later I checked on them and they were crawling with fungus gnats. I put two yellow sticky traps with each flat and returned the plastic covers. The sticky traps are now full of the critters, but I still see some jumping around in there. Next up, the mosquito bits if I can find them!

@Bigfoottehchipmunk 5 месяцев назад

Definitely good to know. I want to deal with the gnats on my indoor plants before I start seedlings. I instinctively did let things dry out, but I think I need to treat with neem, which I have on hand from when I had Japanese beetles outdoors a few years back. I will then put vermiculite on the top layer. I have a cat, so hopefully that won't be as attractive as I think sand would be.

@orionx79 5 месяцев назад

There are methods he didnt mention. Along with the sand you want to water from the bottom keeping the pot in water allow it to wick up without saturating the top. I generally dont like sterilizing my soil but you can mix peroxide and water and water your soil top, the peroxide kills the eggs, Do it a few days in a row and there gone. When i did this i killed all the fungus gnat....but then i got brown fungus growth on the surface of the soil. My ultimate answer was sand on top and watering from bottom i still get a few but no fungus no mass population.
