Will this stuff kill fungus gnats?

Probably not. Neem is a preventative for mites and others, I don't think it helps much with gnats. For gnats you need to kill the larva in your soil, that's what is fucking with your plants. BTI based works the best, Gnatrol is what I use on the regular.

Damn. Well I never actually got that stuff, I ended up getting some spray that hasn't arrived yet. It's vegetable/fruit safe stuff, so it's safe and hopefully it will kill some of them before I can get anything else. What is BTI or BTI Based or whatever it is? I'll check out gnatrol as well.

If it's BTI, that is bacillus thuringiensis israelensis...That is the stuff you need for fungus gnats...It won't kill on contact, but after a week or two you'll see a real improvment.

Here's a wiki link

Yeah I started googling and found out. Would this stuff be okay to use then? http://www.amazon.com/Safer-5162-Caterpillar-Killer-Garden/dp/B001A7RNB6/ref=sr_1_7?s=lawn-garden&ie=UTF8&qid=1352620054&sr=1-7&keywords=B
acillus+Thuringiensis It contains the BTI, as well as some other stuff. But it says it is safe for edible plants, should I get it?

Edit: that stuff is powder, this is liquid. http://www.amazon.com/Thuricide-HPC-Caterpillar-Worm-Control/dp/B004CZ2YBW/ref=sr_1_17?s=lawn-garden&ie=UTF8&qid=1352620246&sr=1-17&keywords=Bacillus+Thuringiensis

Nope, won't work, that's just BT, not BTI...BTI is a specific strain of bacteria that only targets mosquitos and fungus gnats...That BT for catapillars won't work, it's just for catapillars

Do you have a home depot near you? Go get a product called Mosquito Dunks...or get them on amazon...they're cheap...Break one up and put half of it in the water you use to water the plants with, and sprinkle some of the other half on the top layer of soil...

Search "Mosquito Dunks", they have BTI in them for cheap. You can make your own gnatrol that way, for WAY cheaper, and the mosquito dunks are dry, so you just break 'em out when/if you need em.

Yeah I looked at those as well. I'm pretty broke but I earn amazon gift cards online, so I'll just order either gnatrol or the dunks. Whichever are cheaper I suppose. Thanks again for all the help, you're saving my plants!

If you have fungus gnats, you might be overwatering...Try to find the source of the problem, instead of just fixing the symptoms. But happy to help :) Good luck, bro!

I recommend the gnatrol over the mosquito dunks. Ive used both and for some reason the dunks just dont seem to work as well for me. Gnatrol is very concentrated and works 100% for sure but it is more expensive. Either way its an organic way to go and wont burn your plants.

goGnats never worked for me and I tried it for a solid 2 months once. Watered with it + soaked entire root systems in it and it didn't even touch it. Starting to get a couple gnats flying around now and ordered some gnatrol + a couple no pest strips + some gnat sticky paper. I have a feeling it will work this time.

Regular tillage of your soil - deep! - improves drainage and keeps any insect "homes" destroyed. Additionally, use a knife to insert in to your container all the way to the bottom and amputate roots. Cut them. The root then regenerates 2 to 4 new root tips. Do this weekly and rotate the sites you cut but do the entire container within a month. The new smart fabric grow bags work on the principle of root tip amputation. Be sure some of the cuts are to keep the root tips from contacting the container sides. If they touch the side they inevitably turn downward and help start root binding. Don't be afraid to cut any root tips protruding from the bottoms of your containers. The plant will not even show signs you did it except grow better!

You want an end all be all solution to gnats, get a product called GnatMaxx. I am not near my stuff otherwise I could find the company name off the bottle. It isn't cheap but got rid of my gnat issue in my DWC setup in one dose. It is totally organic if I remember correctly as well.

i just used this stuff while skeptical about the product,but it works...
smells like fresh lemons when sprayed.

its made with lemon grass oils.caster oil,small amount of soap..and some of their sprays have nitrogen for veg/clones and their other spray has NO Nitrogren for flower,and can be sprayed on buds like mighty wash.

ive sprayed it on ants,moths,spiders,and gnats that are outside and it has killed them all

DO NOT DO WHAT I DO.. without doing your own research, talking to others, and then assuming 100% responsibility if anything goes wrong..


That said.. Fungas gnats in soil.. very easy.. very inexpensive.. for almost 3 decades this has worked every time.

Mix some standard 3% h202 (hydrogen peroxide) and water (I dunno, a cup a gallon won't hurt a thing)....

Water your plants... yup.. there is going to be foam.

The H202 does NOT harm your soil (I,ll assume you are not organic, and even then), (farmers use h202 in their water in some regions as it helps in the increase of nutrients and provides oxygen to roots in compact or overwatered situations)and your roots quickly repair (you have little creatures destroying them anyway as we speak).

Wont hurt a thing (worse than it already is.. this is a remedy, not a regular maintenance program).. EXCEPT it will kill EVERY fungas gnat larve in the pot.. BUT... you need to hang a strip, or get some vinegar or empty beer or someting to attract the living ones.. they will go right back to that soil and start laying eggs again... get a spray bottle with hydrogen solution and spray and stir top soil for a few days and let the flying gnats die off.

In 'MY' (not to be confused with anyone elses) experience, the plant responds almost immediately.. they really do seem to like that dose of extra 0xygen and they just look so much better and there are no more gnats.


Anyway.. it's cheap.. it's effective.. It's natural..it works.. don't over do it.

Good luck.
