Hello,

I've been searching around looking for a good treatment for gnats in the soil of fruit trees. I'm finding a lot online about fungus gnats indoors, but I have a cherry tree outside my house that I'm seeing gnats in the soil of. I've been organic gardening to date, so would prefer natural ways of controlling them, but at this point even if there's a good insecticide you'd recommend I'd love to hear it. Thanks!
