Just because you don't see them flying doesn't mean they aren't still alive in your soil and/or eating your roots. I use mosquito dunks. You can get a 6 pack of dunks at Lowes for under $10 and it takes about 1/8th of a dunk to treat a 5 gallon bucket. The only problem is that you are supposed to put the dunk in water, so IDK how you'd do it with soil, but it works great in my DWC
I used some Seven-5 dust and it seemed to do the trick, but I occasionally see some more so I'm gonna try the fly strips and venus traps those are good ideas.
hang one of these up your done:thumbsup: works on spidermites thrips flies:hippy:
i think i was told at one time to cover the top of the soil with a layer of sand...anybody ever hear or try that one?
sounds like crazy talk to me...
Yeah i dont know about sand but hey it might work
I see One Huge problem with 1/2 of these suggestions. 1 person already said it JUST BECAUSE YOU DON'T SEE GNATS DOES NOT MEAN YOU FIXED THE PROBLEM!!!! They feed on the roots of your plants the actual gnats do nothing so all you are doing by adding the Venus fly trap is making food for it lol. they harm your roots you need to get rid of the larva in your soil i find drying out your soil some what helps but gnatrol is probably a good idea. I need to order me some i think because they are starting to come back since i got rid of them a month ago...(by drying out the soil.) oh well good luck by the way when you transplant you can literally see the little white buggers stuck to your roots :mad: so get rid of them.
ok i knew i had seen the sand trick before. heres some info
Fungus Gnats
Fungus gnats like to feed on roots of the plants and organic matter. Adults and larvae live in moist, shady areas. The adults lay there eggs on top of the soil, near the base of the stem and takes about 4 days to hatch. The larvae will start by eating the root hairs of the plant then working their way up the plant, Fungus gnats like to eat organic matter so they will be stealing away nutrients from your plants, so its best to get rid of them completely.
If plants are outdoors, check the soil of plants before taking them back indoors for adult gnats or their larvae.
Prevent indoor entry of gnats by making sure there is no open windows open without screens on. Aug is a bad time for them as they are worst that time of the year.
Put sticky traps on the soil surface to trap the gnats
Put potato slices on the surface of the soil. The larvae like it and will be drawn to it.. After about 4 to 5 days, remove the potato slices with the larvae. To get rid of them you can do a lot of things like either use a NO pest strip, neem oil or putting sand on the surface of the soil will suffocate the eggs and get rid of them as well. Tobacco juice kills them, and works well for re-occurrences!
They can be in or on the soil and can fly. In order to get rid of them you can use neem oil, sand on the surface again kills them, and no pest strips catch the ones that fly. A chemical product called Zone works very well and is very powerful and works well in hydro!
Other Products which can be used in hydro and soil are:
Chemicals
Hot Pepper Wax,Safer Yard & Garden Insecticide (which can be used right to the day of harvest),GNATROL( used in hydro in the water as well as soil),Doc's Neem Pest Soap,Safer Sticky Stakes,TR-11000 Pyrethrum.
Ditto, icbh, watch the sand though, too much interferes with soil aireation.
Gnat off or gnatrol is your best bet.
Subzero. :thumbsup:
These little bastards will be back when your soil gets wet. I have battled them for years. What I use now is a product called "Gnatrol". Its a liquid you mix with water and soak the soil with it. Ussually 2 applications does it. Its non toxic, fucks with thier life cycle some how. I recomend it.
