Hey guys just so you know the vectobac mosquito wise or margaret roberts biological mosquito insecticide, same thing, really does the trick at taking out fungus gnat larvae, and once they are gone, no more problem. The margaret roberts organic insecticide does well to capture the adults but leaves thick residue on the plant due to the canola oil.
