Top-Dress and Foliar Spray

Yes, that is a fungus gnat. Not the nastiest of pests, and pretty simple to deal with.

You want Mosquito Dunks, which are available at hardware stores, nurseries, Home Depot, etc. Crumble half a dunk in a 5 gal bucket of water. Let it soak overnight. Use this to water your plants over a period of 10 days or so. Don't go overboard on the drenching, just water with that stuff as usual when the plants are thirsty. It won't harm your plants at all, but will kill off the gnat larva. For the adults, use the Shop Vac...

You can also crumble a Dunk down to powder, and sprinkle a half teaspoon or so onto the surface of your soil.

Thank you, Spicy. Let the truth be heard!

probably not as much as you gave em..............bottom line if you have gnats youre doing something wrong and if you don't fix that nothing you do to kill them will work...... youre either over watering in... 2 small of a pot or have poor air circulation under your canopy.........gotta break the life cycle.. more than likely all you need to do is let your pots dry out......

Yea the pot its in is kind of small but i dont think i've over-watered. Maybe i'll let it go an extra day before watering this time.

If you want to get rid of your gnats I'd suggest you give the soil a chance to dry up a bit...sprinkle a little de around...and POOF! Gnats are gone... :)

not growing the bs so thick at the bottom of you plant next time would help also......... I cant see the level of the soil in your pot but keeping it almost full is big.. you don't want that space w dead air............I would guess the combination of your plant developing a def and the fact that they just don't use as much water on the other side of the stretch was the cause of your problem........
 
Well the pot has been filled to the top since the beginning but it also has a mulch layer so that could be contributing also. I will hold back on the water and see what happens. Thanks guys.

The problem with the suggestions of letting the soil dry out is two-fold.

First it does not work to dry the soil alone for the larvae just go dormant and once moisture returns to the soil so will they.

Second letting the soil dry as recommended disrupts what is taking place in the soil web where micro life are bacteria and fungi are breaking down organic matter and larger micro life nematodes protozoa and the like.

To treat you can take a long piece of fresh potato that would be fry size and lay one each across each soil container. Check after 4 hours for tiny black specs of larvae then dispose and treat that soil container.

You can use expensive natural products like Gnatrol which has a bacteria Bt (Bacillus Thuringiensis Berliner var. israelensis) to treat the soil with or use neem cake dressing and water to kill larvae or even hydrogen peroxide 3% which will on contact kill larvae and fungus gnats.

When using hydrogen peroxide use alone, I spray the surface of the soil as the larvae are only on the top inch or so. Also a regular weekly maintenance program using neem and or hydrogen peroxide will ensure no larvae take hold and damage the roots of the plants.

The adult gnats will disappear in days and pose no problems to treated soil they will die

Though neem has a pungent smell the benefits to using neem cake to top dress soil besides to kill larvae neem feeds the soil nutrients as well.

One of the best traps for adult gnats is to take some small like containers for to go sauces fill with soapy water and apple vinegar, the vinegar attracts the soap helps them drown in the solution.

Obviously a comment from synthetic nutrient grower, the solution provided to grow without wet compost is impossible to do and have active soil web. Fungus gnats are an affirmation the grower their organic soil web is alive and well. They don't have fungus gnats because they poor crap in their soil which is used more as a medium to hold plant in container and absorb synthetic nutrients then it is too feed them using the soil as a biological web to properly feed the plants.

All true organic growers have to prepare to deal with fungus gnats if your going to have great active organic soil. Just know fungus gnat will always be something to treat your soil for because if it is alive and well it will attract them. Just put out the not welcome sign with the neem or hydrogen peroxide and you will be just fine and your plants will be too.

More then likely because the fresh compost or casting will have live bacteria in it, specifically Bt (Bacillus Thuringiensis Berliner var. israelensis which is used in the product Gnatrol.

LOL, what the fuck kind of nonsense advice is that? Having gnats does not indicate that he is doing something wrong. Letting the gnats persist after identifying them would be wrong, but every grower, noob to expert, will have gnats at some point.

And what on earth does the size of the container have to do with having fungus gnats? That could be the most retarded comment I've read on this site. Sig worthy
