I will post later some picture and try to catch a fly on a photo! You think those fly strips will work?

You should have yellow sticky traps from the beginning of your grow, they will help keep things under control.

Chances are your dealing with Gnats. GoGnats is the recommended course of action

gnats were the reason i switched from soil to hydro...
Apartment literally SWARMING with gnats....

Get fly tape. And sand can work, but just remember that you need garden grade sand, because construction grade sand is full of salt and will hurt your plants. That was a hard lesson to learn lol

Yea today i will get some Fly tape

Sounds like fungus gnats to me to... If not to bad you can use cinnamon... I use something called organicide but it smells horrible

several yrs ago a buddy gave me a misquito dunk.its a little donut shaped thing that you put in standing water around your property to kill misquitoes. just a little bit in a glass of water next to your plants will kill gnats in a few days. most hardware stores sell them
heres what I mean

I'm on my first grow too and noticed gnats. The sticky fly trap has really cut down on the amount of gnats flying around. To combat the gnats in the soil I've just been watering less, thinking about putting an inch or so a sand as a top layer of the soil. I guess the sand cuts the gnats up when they try to exit the soil.

I grow in hydroton stone, you'll still get gnats, important to control, they can damage roots if they get out of control. Go Gnats works well, just top spray your medium 1x/week. I also put a sticky trap on in the pot, as well as hanging around the plant. If they get bad, the best product is call Safari, it's been shown in university tests to be more effective then anything else.

[h=1][FONT=Arial, Tahoma, Helvetica, Verdana, sans-serif]Bt israeliensis--- pretty cool...gonna look into this. Gnats gotta eat too....just water from the bottom...then top.. aerate your medium more.... make conditions less favorable for your Gnats and they will stop breeding... sticky traps should be all that you need.[/FONT][/h]

This pretty much accurate.. You will need to use something catch the adults flying around but the real problem lies in your medium those gnats love to fuck on top of your medium and drop larvae deep into your medium so dont get too happy because you think you got rid of some them flying, they will come right back. Dig into your medium and you will find little white specs which are the larvae ( maggots ) .. Good luck I have always used predatory nematodes.

I wouldnt listen to this advice... The larvae is the hard part.. The larvae will feed on roots. Sticky traps only catch the adults. And sure go ahead and dry out your medium and stress your plant who knows maybe you will get a hermie...

Cool I have never even heard of the product Safari.. I have used Azamax, Gnatrol, dunks etc...I was lucky enough to see a fellow grower burn his crop by soil drenching with Go Gnats be careful with Go Gnats its powerful stuff. I have been just using predatory nematodes which are just a ring worm that eat the larvae.

Actually allowing the medium to dry will help because the gnats and larvae need wet conditions...so you let everything dry out...that is also what they said is for on the top of the soil...not to cut the gnats, but to make them unable to reach the soil underneath that is moist because sand is too porous and doesn't hold moisture...so the drier the better, make sure you don't have any standing water or open jugs or bottles or whatever...hell an old wet towel can keep a colony of gnats going for weeks...lol.

I had them and used neem oil...it seemed to reduce them, but I don't think they were ever really gone...they don't really hurt an older plant, unless you have a super invasion, or they got really bad before you noticed....but the adult gnats are just annoying, but don't actually harm your plants directly...they do lay eggs in your soil that hatch into larvae that eat your roots, and will even eat out up into stems if left to worsen.

I tried cinnamon once. Complete waste of time and money. My gnats seemed to love that stuff. I tried dunks recently too. I can't say I was very impressed with those either. Good luck.

I kind of agree I wouldnt dry out my medium I tried that and it just made my plants sad like they wanted water..But I agree they wont do as much damage as you think its just annoying because they will get stuck in your buds and you will have to inspect your buds and remove the flies that get caught in the sticky buds or you will be known as the guy who has fly infested buds..If you shake your tree and you get a lot of flies on your arms I would just consider that severe infestation.

A trick I did was put the fan on high to keep the adults from flying and then I took a couple sticky pads and rubbed them on the trunk of my plants about 10 inches. This caught a bunch of gnats that were trying to climb up the stalks.
