Fungus Gnat Info for You!

I recently (well still, too) was battleing a fungus gnat problem. After reading everything on here i could find, and elsewhere on the net... I started to fix the problem.
They got bad, , usually i could count 15-20 flying around, and this is in a small space.
So i set some traps that i read about, beer, wine, sugar water, soapy water, None of them worked..
I let my soils stay much drier, and they still proliferated. something was always being watered, and something was always moist enough for them i guess.

I went to the garden store here, armed with the nematode knowledge i read about, and was ready to kill these things.

I was sold Gnatrol instead, being told that it was the biological superior.
I opted not to buy the yellow sticky traps. im poor and spent a bunch on the gnatrol.

Well, the gnatrol killed the larvae, and the gnats slowed down some, but they came back quickly, as the living ones were not affected and layed many new eggs.

I got yellow sticky traps the other day and there is tons of gnats on them. they are getting filled more quickly each day.

The problem has subsided.


MORAL OF THE STORY. Get the soil larvacide, wether bacteria or nematode, and something for the living flies too. any safe spray will work too, or the sticky traps if you want to keep your vegetables more edible.

Mosquito Dunks = Gnatrol... really cheap. 1 tablespon of MDunks to gallon of water, soak overnight. More water can be added to the residue left after pouring and reused.

Top dressing soil with diatomecous (spelling?) earth gets the parents too. Throw in a few Shell No pest strips and turn off the fans one night....

DIE FUNGUS GNATS DIE.....

Bacillus thuringiensis subspecies Israelensis strain EG2215

or Bti for short

That's the "active ingredient" you're looking for with fungus gnats.


I like the Mosquito Bits to the Dunks. I have rain barrels outdoors and just a sprinkle of the bits is all it takes to kill the larva in the water... usually within a few hours.

Put some water and dunks/bits in a bucket and use just a small cup of water from the bucket with each watering. Add it to your solution or whatever.

I have a nursery in my backyard. They have them in stock. I'm sure a place like Lowe's or Home Depot would have them. If you have access to one of those stores. They seem expensive but are well worth the price.

also remember that the adults live roughly for 4 days. if you water with gnatrol or mosquito dunks, do so again in 2 days. this will be sure to kill anything that the adults laid in the time from the first watering. the one two punch is usually all you need.
