Partner, the SNS 203 worked great ridden me of the Thrips infestation I had but was some what lackadaisical handling the fungus gnats. I get much better results using Broke Azz Gnat Spray:
One quart h2o (I use tap), One cap of Hydrogen Peroxide, & a small drop of liquid Dish detergent > put in a spray bottle > Shake well > Spray the leafs & medium generously once a day for 3 days > Gnats & Larva gone.
