If you have potted plants in your home, then you’re probably no stranger to fungus gnats. These tiny, flying insects like to eat fungi, and the fungus gnat larvae thrive on the decaying organic matter in overwatered indoor plants. Fortunately, you can learn how to get rid of fungus gnats with hydrogen peroxide.
