Best insecticidal spray for fungus gnats

… the gnats appear if your soil is too damp on the surface. Water completely but less often and that will prevent a reoccurrence.

I use the Mosquito Bits almost every watering. I will see maybe one or two around once in a while still. Much better than when I was not using it and was just using the sticky sheets.
