The first gnat is easy to ignore. One tiny insect drifting above your plant or circling your kitchen sink hardly seems like a serious problem. But then another appears, and another, until suddenly your peaceful home is filled with tiny flying shadows. Warm weather can bring fungus gnats around houseplants, fruit bowls, drains, and trash. They don’t bite, but they reproduce quickly, turning lights and countertops into gathering places. What started as one harmless insect can soon make your home feel frustratingly out of control. Fortunately, you don’t need harsh chemicals to fight them. The key is breaking their life cycle by targeting both the adult gnats and the places where they reproduce. And the first place you need to look may be sitting right in front of you: your houseplants.
