Damn. Well, after not being able to find the dunks or gnatrol, I resorted to watering from the bottom. I have never had a product that worked as good or fast as bottom feeding. Once that soil surface dries out, the gnats leave.

If you were to bottom feed for about a month, your gnat problem will disappear. Take it from a grower who had a severe gnat problem due to compost. I tried everything around here, but bottom feeding was where its at.

Good luck. No reason to freak til they pull Avid and Floramite off the shelfs. Then we are in for it.

One more thing... Fungus gnats in small numbers are actually not a bad thing. They are among the pollinators of the bug world. I see em from time to time but never had any ill effects from them.

They are still available where I'm at in northern California.
Are you in Canada by chance?

Has anybody had any success using Azatrol or other azadiractin product as a soil drench to control/eliminate fungus gnats?
I don't mind a few fungus gnats, but they seem to be very bad for young clones, before they are rooted.

i use azatrol once a week for mite control, it seems to work but i dont know about the gnats.

Gnatrol is a highly selective, biological larvicide for use in greenhouses to control fungus gnat larvae. It may be used on a wide variety of ornamentals, as well as all bulb crops, bedding plants and vegetable sets. The active ingredient is Bacillus thuringiensis israelensis (Bti). Once the larvae have ingested the insecticide, protein subunits paralyze the fungus gnat larvae, which stop feeding immediately and die - usually within 24 hours. Will not harm people, pets or the environment. Mix 1-2 tsp. / gallon of water. For heavy infestations use 4-8 tsp. / gallon of water.

As part of an Integrated Pest Management (IPM) program place Yellow Sticky Traps horizontally to control adult fungus gnats.

Stupid ass dang moths won't stop this grower from obtaining large quantities of the good stuff.

I've been using some bti (mosquito dunks and some drops) in almost every watering and have still had waves of gnats. For the first time though last night i saw a small swarm in one pot and it really freaked me out. I have no problem bottom feeding but was wondering if the chloramine in my water (which apparently isnt filtered out by most systems including ro?) might be killing the bti before it has a chance to work? Supposedly it (the chloramine) is neutralized by the organic matter in soil but that doesnt help the poor little bti's - I wish I had a real microscope and slides to see. Was able to find some studies online but they're not really in plain language and I can't tell how much chloramine they used. Anyway, just figured I'd ask on this thread.

Fungus gnats hate dried garlic powder or flakes, sprinkle on top of medium and mainly around the stem. Always water from the bottom, even if you don't have fungus gnats. Just from experience.

Cant hurt right? Some greenhouse flower growers plant garlic plants to keep thrips away. But what if I'm also trying to kill larvae from the eggs that are in my soil mix?
