Hello! New to this community, but thrilled to be here! I’m struggling with the wrath of fungus gnats, specifically in my giant monsteras. I’ve done a hydrogen peroxide flush and watered with mosquito bit water and sprinkled mosquito bits on top of the soil. I also have sticky tape to catch the grown-up gnats, but I’m still seeing them! Any other tips? Do I need to just replace the top few inches of soil?
