Yeah I've already used mosquito dunks and they're not an effective method for me
Yellow stick cards at pot level is the cheapest way it takes 2 to 3 weeks but you will see the population go down drastically immediately. If you aren't hanging at pot level though they will be less effective
This won't kill the larvae in the soil though and that's the real issue cause they eat the roots.
They won't kill the larvae but the adults don't reproduce and lay eggs when they are dead by controlling the adult population you diminish their numbers that's why it takes a few weeks to completely get rid of them. I've tried most of the ways mentioned and that is whats been the most effective for me. Even if you use food grade DE and water from the bottom they willl just migrate from the top layer of soil to the bottom of the pot.
Go home depot get a bag of Coarse sand the rough and gritty type, get a dish for your pot to sit on and a bag of pebbles. Now fill the top of your pot with 2-3 inches thick of sand and fill the bottom tray with pebbles. When you water your plant the sand and soil will mix a bit don't worry about it.now the gnats can't bury into soil to lay and even if a few manage to get through there larvae is gonna cut itself up against the coarse sand, pebble on the bottom coz once they get blocked from the top they will try to go through the pot holes.
This is a gnat too!is this a gnat? it was alive so figured id take a photo of it before squishing the fucker but not sure it wasn't black like the others i've seen.
not really, inside in a room with carpet though. i figured i might have tracked it into the tent cause i couldn't see anymore just this one little bugger. and it doesn't look like any fungus gnat pics ive seen closeup on google lol
