Fungus Gnats

“The 100% cure for fungus gnats is circulation. You don't have to do anything except circulate air over the tops and bottoms of your pots. If you have holes in the sides of your pot, get them circulated as well. Don't give adults a chance to land and lay. You will have the larvae in the soil go adult and get blown away.”

That’s good advice. I had a few gnats and adding fans that blow across pots 24/7 Got rid of them. As I was advised here, if they can’t fly and land on the soil they can’t lay eggs.
 
air flow + yellow stickies + hydrogen peroxide mixed with water to kill the already existing larvae = 0 fungus gnats
 
Well...nothing is 100% foolproof. I have seen FG lay eggs in the soil spilling out of the bottom of the container. Spilling through the holes on the very bottom.
Also if your source of contamination (FG eggs) is coming from outside of the garden, like in the soil brought in from somewhere else, no amount of wind can stop that.
 
Toker1 I’m pretty careful about my grow space environment and I’m assuming that they didn’t come in with the FFOF soil. Everything I’m using is new. I have prefilters on all my inlets. They find a way in I guess. Probably when it’s open I imagine.
 
So far the baking, DE, fans, smashing what I see worked! I did get the spinosad and spry as a preventative of returning and for other bugs.
 
I’d almost swear you get a free batch of eggs with every 1lb of living soil. In all the years we’ve had plants of all kinds, never had them ever
 
So far as gnats, and in my experience, now all you need is circulation over the tops of your pots and any other holes, like drainage. They will get to your soil anyway they can.
 
Welcome to indoor growing. Pests are just everywhere. The pest’s eggs and mold’s spores can potentially travel into your garden on your shoes or clothing. Nature finds its way inside in some way/shape/or form. If the pests were not good at seeking out plants and food, then they would have a tough time surviving on this planet for as long as they have.
 
Toker1 I naively thought bugs wouldn’t be much of an issue in a more controlled indoor environment. I can see why GWE devotes so much space to bugs. The spider mite stories are getting my attention. Going to replace my empty bottles of spinosad and Neem tomorrow.
 
Yeah.. you can add predator bugs to your environment. The problem with indoors is there are no natural predators to keep the pests in check.
 
Toker1 someone here was saying that ladybugs might get into your light. Mine would be easy for them to get into and cause problems. I’ve always used ladybugs for my outdoor grows. They keep the plants clean and I love having them around. (See profile pic 😊)
 
Lady bugs and praying mantises are definitely a growers favorite. Because they devour many types of pests. Some predator bugs are better than others depending what you are infested with.
Releasing lady bugs into your indoor grow room simply won’t cut it. You need to establish a lady bug home with food and water so that they breed indoors. That’s how you can effectively use them inside.
 
I ran across these from an experiment I did.
A small pot of soil. H2O2 and water. It's cool like watching a cupcake bake. The upside is you have some well oxygenated soil. The downsides are you killed a bunch of other beneficial stuff in the process, and not everything you are trying to get rid of, goes away.
And it's fun to watch.

And old farmer trick is to cut a potato in half and burry one of the halves (the insides of the potato should be facing downward) into your soil. The larva will make a home inside the cut potato, in a few days you remove the potato and all the larva inside it.
 
this method is usually used to just check for the larvae, not get rid of them entirely. A hydrogen peroxide mix with water fizzes them out of existence.
 
starramus. I’m definitely not an expert and have never tried that but GWE said something about HyPer killing off beneficial microbes too.
 
starramus good to know thank you. Growing indoors is much more difficult than outdoors. At least in my experience.
