How do you kill Gnats?

I have gnats in my grow closet pretty sure they are fungus gnats. I have tried sprays, cleaning the grow closet and switching soil and letting the soil dry out more before watering. Nothing is working how do I kill these things. On I treated the soil for the fungus as well.

GoGnats kills them for me in 1 treatment usually.
that or Diatomaceous Earth

I had a gnat problem before i watered with neem oil and and a tiny bit of washin up liquid then covered the top of the soil in a inch of sand then Hung some sticky fly traps up in tent solved my problem

crushed mosquito dunks top-dressed onto soil. a fan facing a sticky trap depletes their numbers too.

told you so.

Yeah I know. It was weird there where no flies I mean no flies for over a day then more must have hatched and it was quite a few. How dow you use the mosquito dunks?

lots of different types of bacillus are effective (mosquito dunks, gnatrol), go gnats is a decent product, sticky pads for catching them flying, or u cld just dry em out

the dunks are bacillus and u just break them um and put them in the water. they are designed for things like rain barrels and places where there is standing water

I hire Chuck Norris for an hour.

that was really easy and effective to catch the adults flying around. I also used some stuff called azamax, ~$30, to kill the larvae in the soil. It's botanically derived so its safe for plants/humans. you are still in vegg?? correct???

Thanks I will try that.
