I have a fungus gnat problem that i thought i had under control with Diatomaceous Earth. I noticed several of my lower leaves turing yellow with dark scarred specks from some sort of 1mm larvae sucking the life out of my leaves. they look like a pic of fugus gnat larvae but every where i look says they dont live on the leaves. this only started to happen after i applied the Diatomaceous Earth to the soil in my pots. will the gnat lay eggs on the under side of leaves? what would be a good remedy to solve this solution? I would prefer an organic solution but am open minded to other solutions.
