Gnats are a problem because they thrive in moisture-rich environments like overwatered houseplants, dirty drains, and areas with leftover food or sugary residues, making them difficult to control. While they don’t usually bite, gnats can contaminate food, spread bacteria, and compromise household hygiene. The rapid reproduction cycle of gnats can lead to large infestations, creating a nuisance and posing potential health risks. Prompt action is essential to prevent their spread and maintain a clean, sanitary living space.
