it might work, beneficial nematodes are also really effective if applied weekly or bi weekly

I was thinking of leaving the light on during the night outside the tents, the bugs will probably fly around and come to it, to die.

Dude, circular UV bulb around a 3500K COB.

Really? How does that work?
Until I seen that picture I had yet to ever see a circular UVB bulb.
UV is missing from LEDs, iirc because itâs prohibitively expensive. Imagine if you will, a single cob on a round heatsink, set inside the circular UV bulb. The fan may not even be necessary, but it would be a welcome addition.
Not sure if it works for gnats but one would think it would. The pests are very similar once they are airborne. It âcouldâ at least replace the sticky traps. Cool find and while I hope no one needs to use one, it would be cool to see a review of one.

interesting. I need some of these just for mosquitos in my hallways.
Playground sand is the cure.
I have tried many things to get rid of these Lil bastards and have figured out a very cheap, clean,organic, dam near Imediant way to get rid of them. To start Iâd like to say if there naturally present in your area which they should be if you have them, unless you got clones or dirt from afar with the larva, they will continue to reappear. If one or two sneak in after you kill them off couple a hundred eggs are instantly back in your medium and the cycle behind again. Back to the sand, go to your local store and get a bag of playground/sandbox grade sand ,it is the finest and works best. Spread a 1/4 - 1/2 inch layer on the top of your plants covering the soil completely. The sand dries out after watering extremely quick and is to fine and compact for the knats to want to bother digging into to lay eggs, this will end the cycle, if you want really quick results do this and then set off a permithium bomb to kill adults. You will be amazed how well this works , only down side when you water the sand moves around and you need to make sure to recover any exposed soil, also makes it hard for a in expierianced person to tell when they need to water, apply sand water and pick up pot to get idea how heavy when wet.

This is going to sound odd n I might get shit 4 it but i swear it works. Cover pots with 1 inch of sand. Itâll block easy access to the adult larva from laying eggs. The larva inside the pots will still leave through the drainage holes and continue the cycle. So put slices of potatoes on top of the sand. The adults that survive and come out the drainage holes will lay eggs on them. Since theyâre easier access then the drainage holes. Replace them every 4 days. Also put out shot glasses half full of red vine vinegar. Theyâre attracted to it like catâs to catnip. It works 100x better then sticky traps. They will either drown in it or lay eggs all around the glass. Clean and refill every 4 days.

@DankyStank619 Hi, I see this post is not that new, but I use nematodes against Fungus Gnats, also activated Microorganisms called EMA are said to make them impotent, also you can use hot extracts of garlic and ginger to fight those suckers.

i use mosquito dunks, in the disc form, and also i found some in a jar, they look like bacon bits. haha
it keeps them at bay, i always have a few gnats. i do not treat unless the population explodes. 95% of the time i have no worries with them. i may smoke a few strays that got stuck in the buds, but that really does not worry me. i have noticed several small spiders in my grow cabinet, i leave them there.

Last winter, I got lucky, and for some reason, they kept away. This year no such luck.
I have tried some predatory mites, but may have fumbled the ball with them. The gnats are starting to surge again.
The only way I have found that I can tolerate them, is to move the grow out of the house. Dreamin big!

freezing does seem to vastly reduce them. I stocked my garage with enough bags of soil mix and compost to last 2 years, hopefully the sub-zero weather will wipe them out. They donât come in the garage in the summer.

Best thing for gnats in soil is heat. You can leave bags in your car on a really hot day. Also maybe an attic that gets super hot in the summer. Or black trash bags flat 5" thick on your driveway in the sun.
