Help Growmies! Maybe you guys can help me out. I have fought fungus gnats for what feels like an eternity. I have tried everything I can think of. Less watering, Diatomaceous Earth, BTI and even drying the soil out which isn’t good for living soil. But still these fuckers come back. Suggestions?

I've never tried but I herd letting some lady bugs loose in your tent will really do justice.

I’ve heard good things, i just don’t know how i feel about having lady bugs in the house🤷🏻‍♂️

I've had success with spinosad, typically spray prior to flower and then a topsoil drench, just enough to wet the top 2" or so, not sure how well it will play with living soil for those 2" though.

I have been doing pest control for over 12 years, you can buy a electric fly light on Amazon the one with two tube bar lights on it $40 , get a giant rat glue board but a banana peel in the middle of it

Now this sounds interesting 🤔

Here’s a link if you never heard of them

I’ll try Biocontrol and Canncontrol, whats left honestly lol

eBay bug zapper, turn lights off about 15 minutes early and run the zapper

Try putting a small bowl of apple cider vinegar at every point of entry heard itll work.. but Iv never tried so get back to me if you try and it actually works

Rove Beetles are the truth. Arbico has them.

Buy "Mosquito dunks" and keep one in a cup of water. They will drown in it. You can also buy this yellow sticky paper that attracts them and they stick to it. I use the mosquito dunks with good success. I've never tried the yellow paper but I hear good things.

I do get a lot of the a adult gnats this way, it’s effective but i gotta break their cycle

Nematodes, never tried it but read it’s effective. I use yellow sticky traps, neem oil, & D.E., none of it worked. But my buds did come out fine, (growing in DWC tho) and I was fighting a lot of them. In retrospect I was probably smoking them stuck to my wedding cake 🍰 but I’m alive and got high af sooooo, whatever works lol

Hahaha little bit a protein never hurts 😂

Microbe lift bmc! I had a pretty bad infestation with my plants, worked after a few drenches!

I’ll check it out! Thanks!

Use sticky traps!! That happend to me when I ran out if soil that I got from the grow store. The soil from home depot gave me the worst gnats! Hang the traps at canapy level. They will help greatly reduce the amount u have.

Believe me i gottem in there! Hahaha

I use mosquito bits, I soak the bits in water for a little while in cheesecloth, then water plants once a week with it and it kills them all.

Heard using those clay beads on top of soil will prevent them from being able to hatch. Never had the problem tho

You a lucky person lol

Gantral or azamAx soil drench 1-2 times a week for 3-4 weeks….honestly unless super bad I wouldn’t even worry about it a few gnats isn’t gonna hurt final harvest

Ive been using Gnatrol twice a week for I believe two weeks now and i guess its helping a little bit really haven’t seen a big difference so far. And its like a damn infestation unfortunately

Let soil dry out and then water with a mixture of 1 part hydrogen peroxide and 4 parts water. The hydrogen peroxide will kill the larvae on contact. Follow up with sticky sheets to catch any remaking gnats.

Hows that gonna go for living soil though? I will do this if i run out of options though thank you!

I’ve been looking into Rove beetles

I’ve actually seen them in my soil with my microscope! 😁

Nematodes will kill em at the source; the roots. mercenary has worked well too but I use it for mites mostly

I’ve heard a lot about nematodes but hadn’t given them a shot yet. Where do you suggest to buy them from?

Nematodes!

Gonna look into it!

Mosquito Dunks one per pot , spray top of soil with essential oil mix, let that shit dry out in between watering.

I did that but with some neem and peppermint oil, effective but not completely with my situation. Thank you!

You need to use beneficials to nip it in the bud mate. Mites, nematodes and beetles are your friends here.

Do you have anywhere you recommend to buy from for beneficials?

Mosquito bits. Sprinkle on top of soil liberally and water in. They release a bacteria the gnat larvae eat that kills them. Along with Yellow Sticky Traps its the best way i've found. When you start each grow build your pots early and water them with bits before you even plant. Then add some more on top two weeks after the seeds sprout. I keep gnats knocked way back this way. Some grows don't see any.

Definitely didn’t think about putting the bits in the soil and on top but makes sense thank you!

Mammoth 🦣 P them and don’t look back ! Works wonders I got rid of everyone of mine !

Like Mammoth P for phosphorus or like Mammoth Canncontrol?

Have you tried the bottle trap trick? Like some sugar water or soda and they get trapped in there... or at least most flying pests except mosquitoes... I think it should work for gnats as well but unsure.. I figured it was worth a mention

That similar to the apple cider vinegar trap?

[удалено]

I appreciate it! And yeah my 2gal grassroot pots have like a 2-3 week dry period before transplanting. Tent also gets a complete wipe down twice in that time period as well. I think they just reproduce faster than i can kill them lol

Sometimes living soil can be a bitch huh 🤔

Just like life I suppose 😂

Water when the light first comes on and dont keep the soil soggy. Let the soil dry out before watering again.

Get a full garlic bulb,plus 4 hot chilli peppers.Crush these in 2lt of water.put in spray bottle n spray pots floor,everywhere bar the plants n pot surface.bet that does the trick👍

Hmm 🤔 they don’t like the garlic and hot chili peppers huh?

change the soil in addition to traps

As long as it’s not super infested with them your plants will be fine but I also put fly sticky traps right near base of soil to help combat them but always have some

diatomaceous earth, thank me later.

I use it lol believe me lol

Put some apple cider vinegar in a bowl pr something and secure it but leave enough room to make a good dimple. Poke a hole in that and it should attract the gnats they go in and can’t find their way out.

You might get some but not all I’ve tried this before they just continue to multiply throughout the grow.

I ran out of characters for the title, but man I’ve tried that too i even did that with water and misquote bits

Praying mantis!!!!
