whats the worst the gnats can do?GroWell > Fungus Gnat Off get that and youll have the last laugh,,,,,,,,,,,,,,,,,,,peace
i just did a little research, and could buy a gnat killer from my hydro store for like 25$ or mosquito dunks, i read to submerge them in water for a day and then water your plants with the water, it kills larve, up to 30 days. hme depot or lowes has them, can anyone back this up?I think that a part of treating the problem has to be to examine your reason for infestation in the first place otherwise the problem is likely to just occur again. Fungus gnats are attracted to damp conditions and organic materials so if you're growing in soil particularly, you might want to let the plants dry out a bit more and maybe look at using a different type of soil or covering the top layer with some kind of inert material. If you are intaking air from outdoors check the area outside around it and make sure that it is not around other outdoor vegitation which is also infested. You should also look at what kind of ventilation and air movement you have in the area as stagnant conditions favour pests. Removing all your plants from the area and giving the place a thorough clean may also be beneficial. A good long-term solution, particulary if you find yourself prone to infestation or your infestation is particularly bad, may be to invest in some nemotydes such as hypoaspis miles, which are also less risky to your plants than an insecticide based product
Not sure why you quoted my message in this post. Any kind of insectitcide would potentially work but as I pointed out, your approach to remedying the situation should include eliminating the infestation you already have and PREVENTING it from reocccuring otherwise you might find yourself fighting a losing battle.i just did a little research, and could buy a gnat killer from my hydro store for like 25$ or mosquito dunks, i read to submerge them in water for a day and then water your plants with the water, it kills larve, up to 30 days. hme depot or lowes has them, can anyone back this up?
i quoted because i would like more of your input, i think that my soil is the caper. its a home depot mix with perlite ans such, maybe next grow ill go with ff soil, or just hydro.Not sure why you quoted my message in this post.

The more organic material your soil contains (eg. a high percentage of peat moss) and the wetter it is, the more likely it is to attract fungus gnats. Are you allowing soil to dry out between waterings? It might be worthwhile when treating the infestation with an insecticide to also place an 1" layer of some kind of material like clean sand (try playsand made for kids sandpits) or pure perlite/vermiculite on top of the soil as these bugs live and breed in the top layer of the soil and and as they favour organic materials, they do not like living in inert materials such as this. If you plan to repot your plants any time in the future, you should try to carefully remove as much of the current soil as possible, especially the top layers and dispose of it and use new pots that are clean. Be aware that they easily spread from pot to pot so you should tackle all pots at once and expect that any new plants you introduce to the area are likely to also become infected.i quoted because i would like more of your input, i think that my soil is the caper. its a home depot mix with perlite ans such, maybe next grow ill go with ff soil, or just hydro.

i am going to try the dunks, do i acually water my soil with it as a water? or a spray? or does it just sit in my room in a seperate container?I tried the mosquito dunks (which have BTi in them) and that did seem to help. If you can find some Gnatrol (also has BTi ... some hydro shops have it or something similar) that worked better for me, but maybe because it was easier to get a correct dose. I doubled their recommended conecntration and drenched the soil on two successive waterings, and used flypaper to catch many of the flying adults (this didn't work all that well, but did catch some of them). I no longer have any gnats and its been 9 days since the last drench. I'm convinced they originated from dormant eggs in the potting soil which apparently is very common. Best to treat the soil with BTi before planting or transplanting if you can't cook it to sterilize beforehand.
I don't know what size "dunk" you have, but these things can usually treat many gallons of water so you may want to break open the package and use only 1/4 of it (or so). If you have a 5 gallon bucket just fill it with water and drop a dunk into it and let it sit overnight. Give it a good stir the next day and water your plants with it normally, making sure to drench the soil completely and get some runoff from the pots. Wear rubber gloves and don't touch the contents of the packages or the treated water!i am going to try the dunks, do i acually water my soil with it as a water? or a spray? or does it just sit in my room in a seperate container?
thats awesome thanksI've found that when using soil, adding some water to it and sticking it in the microwave on high for about a minute or two will kill just about anything living in the soil including larvae. Just be careful as the soil will be super hot and steaming when it's done. Just let it cool (I put mine in the freezer for about 15-20 min.) and your soil is good to go. As one would expect, this method won't help you at this point but is great at the start of a grow to prevent bugs.
