Have been using fly paper. 20 rolls for $8.00. Works wonders.
The garden safe stuff is neem oil, for fungus and insects of on leaves.No, pasteurize the potting soil, I use a 2:1 ratio of dirt to boiling water, put the dirt in a 5 gallon bucket, pour in the boiling water, let it sit for a day.
It would be best to let that soil fully dry out again before using it, just to be sure, but it is now wet and okay to use right away.
Do not use that "Garden Safe Fungicide" if it has permethrin or pyrethrin in it, I tried it for thrips and it fried my leaves.
Honestly, if you pastuerize first and then use the Bits, you won't need anything else.
Yeah, I did pasturize my soil, but since you said that, I haven't treated that bag of soil that came in.No, pasteurize the potting soil, I use a 2:1 ratio of dirt to boiling water, put the dirt in a 5 gallon bucket, pour in the boiling water, let it sit for a day.

The mosquito bits are bacteria that eat the larvae, looking forward to getting that tomorrow.It's not the fungus gnats that caused the damage it's their larvae. You can spray and spray until you turn blue but until you get Beneficial nematodes in the soil to eradicate the larvae you are not going to resolve this problem.
I'm getting mosquito bits for the gnats.I too have been fighting fungus gnats the last few weeks. I even started a thread in here a few days ago asking how people steam their soil. (Getting the plan together for the next round). Got a couple replies, mostly people wondering why the hell I would want to do that.
^ and that is the response I really needed, thank you.
I know, they’re more annoyance than problem. But it’s borderline infestation… and it’s/was February…. Gardening experience tells me this could be a nightmare come warmer weather.
Makes more sense to me to try and pasteurize and do some recharge work to the soil, because spraying more oils/chemicals on the grow media than water… just ain’t right.
Quick survey: seems I’m far from alone and at the same time fighting these little bastards… Did y’all buy/use some FFOF by chance? No proof, but I have a strong hunch it is the source of my problem.
Yep, been using lavender oil getting neem oil soon.Fungus Gnats do not chomp on leaves. If you have something eating leaves it's not the Gnats.
Gnats are simple to get rid of. A neem oil or basically any oil, canola, sesame, etc... sprayed on the surface will effectively eliminate them.
Make the tea !!! It’s the best !!! Make sure it’s hot water form your sink not boiling but not warm either.I like the mosquito bits stuff, looks like it's good for fungus gnats.
Is diamectous Earth also good for gnats?
I'm still going to buy a neem oil spray I think because I've heard good things about that for cannabis as well as controlling fungus and mildew.
Nope, and I don't like the way it makes my weed (or anything else it's sprayed on for that matter) taste.Why's that?
You don't like the smell?
Yep. Totally going to make the tea.Make the tea !!! It’s the best !!! Make sure it’s hot water form your sink not boiling but not warm either.
Yes it’s the best !! make sure to let it cool also before watering cause the water is going to be really hot.Yep. Totally going to make the tea.
Will leave some in the pots too after I water.

I was in a local hydro greenhouse a few months ago, and they were growing lettuce in a deep raft system. As I was talking to the folks there, one guy started suiting up to spray some crops. I asked what they were spraying, and they told me that it was neem, because they had a PM issue. I asked, "doesn't that affect the taste?". They said, "no, it degrades on the plant very quickly". They offered me a few heads of lettuce to take with me, so I graciously took them, and said thank you. As soon as I got out of the greenhouse, I smelled the heads of lettuce. Smelled like neem! I wasn't gonna eat that crap, so gave the lettuce to the chickens.

I'll try to use lavender oil first on my cannabis and never neem oil for the flowering stage.Nope, and I don't like the way it makes my weed (or anything else it's sprayed on for that matter) taste.

I personally would avoid any oils which have strong smells with cannabis (during flowering at least). I don't really want my weed to smell like lavender, unless that's what the cultivar is supposed to taste like. Sesame oil works pretty well for pest prevention, and has no real odor, but not sure how it works on gnats. Your mosquito bits will help, but may not completely get rid of them. I've heard of people using spinosad drenches for gnats, but spinosad use is questionable in some circles, despite it being organically based.I'll try to use lavender oil first on my cannabis and never neem oil for the flowering stage.
I'll be using the been neem on my primrose and peace lily... That's where the gnats are.
Haven't planted my cannabis yet.
What’s your preferred product to spray with?I've been spraying the top of soil and coco at the first sign of gnats for years without any issues. I also don't have gnats.
what would be your preventative or beneficial additive strategy at the start of your grow?I don't understand how anyone grows anything without 1st researching what beneficials they should have in their soil to prevent these types of things from happening.
I use DIY home remedies. I've switched over to sesame oil from neem since I use sesame oil for cooking and always have it on hand. 1/2 tsp in a quart of water with a drop or 2 of soap sprayed on the surface of the growing medium is what I use when I notice any gnats. After spraying that I don't notice them anymore.What’s your preferred product to spray with?
