Hey folks! I have a serious gnat/fly problem that I just can't shake. I've been spraying with a fruit and vegetable insect spray about once every two days, but the darn things keep coming up out of the dirt. I want to soak the dirt somehow to kill the larvae, but not sure how to do it. I mixed up some of the homemade insecticide from a recipe found on this site (clove, chili pepper, garlic, soap). I'm just not sure how to apply this properly to kill the larvae. Any help is much appreciated!
