Nats!Nats!Nats!

I already over water and but have let them dry now for a few days and they are starting to look a bit better. But since they have sprouted I have had nats I hung sticky tape-nothing and now that the soil is starting to dry I will need to water. Are the nats coming from the soil? and what do I use to kill em?

I hear ya,, me too,, everytime the dirt dries out a bit those dam nats come out of the soil,, lots and lots of them,,, I have to keep sprayin them with soapy water but they come back in like 2 days,, then the soil is moving with them little bastards..... I have 4 fly strips hangin w/ those nats all over them...............

if you let the soil dry out completely (like wait a day past when you should water) any remaining larvea in the soil will die. the moisture is what keeps em alive.

tried that one,,, didnt work,, just short of my plants dying, I let them totally dry out everytime and still nats, nats, nats.........

you using MG organic soil?

Organic soil

ok first try diatomaceous earth, its a powder that you spread on the top soil and prevents them from getting to the soil. If that doesn't work, use predatory nematodes, they work the best but they can be expensive.

if you have any soil left, open the bag and take a close close look inside. i guarentee the knats were in the bag before you even bought it. leave the bag of soil open for a couple days so that it dries out. then replant with the dried soil.

Yes, the gnats are probably coming from your soil, if they're fungus gnats.
They're quite common seen with inside grows and are a result of not letting the soil dry out enough between waterings. It seems I've always a few flitting about and they've never (in 30+ yrs) ruined a grow of mine.
If they thrive and get out of hand, they do burrow down and feed on roots, which can (I've read) destroy the plant(s).
I've never dealt with them myself. They just seem to come and go here, and it could be due to my lower grow temps in this old house. I've never seen a few turn into a bunch, but have read of a couple RIUppers who have.

If you feel the need to try and eradicate them, here's a fix to try. Stop watering.
Place raw potato slices on the soil surface and leave. After a while, lift the slice(s) and IF it's fungus gnats, the larva should be in the potato flesh. Discard and replace. (Flush the old down the turd-lette?)
When you don't find larva twice in a row (on fresh slices, after some hours) then the larva is gone and your outbreak squashed.

Be sure to allow the top few inches of your soil to dry out, as in this moist soil the gnats lay eggs.
I've also read that a layer of sand on top of the soil helps?

that sounds like a good idea...... just might work.....

One thing obout gnats Ive noticed is that my grow has always been infested with mites (the worst ones) but since the gnats they have all dissapeared,, I wonder if thats what they eat.... Oh well anyway thats why at first I didnt worry about these gnats, but now they are out in force,,, Im going to try that potato slice idea, i will get back to ya nughed...

Diatomecious earth is like fiberglass to soft bodied insects. Any contact will cause vulnerable insects to scratch at their ectoskeleton, which cause lesions that cause the insect to dehydrate and die.
Food grade DE is preferred . . . it's used in feed to worm beasts.
You're not supposed to breathe this stuff in.

Outstanding!!! I will try that and let you know thanks for all the help.

Say it kills insects, Never used it though...

I got the little bastages about a week into flower. The glue traps caught a lot, but not all of them. I bought pyrethrin spray and goGnats! cedar oil. I put too much goGnats! in the rez one night and bombed the tent with spray. Next morning there were no more gnats. Unfortunately, the cedar oil screwed up the nutes in my res, and I ended up having to flush and clean my rez. Gnats have been gone for over two weeks.

I now am using glue traps and I use a solution of the cedar oil to spray on the media surface. Any live ones are getting caught, and they won't go near the coco to lay eggs......
