Where Do Gnats Come From?

Gnats typically thrive in warm and moist environments, making them common in areas with high humidity. Outdoor gnats are often found near decaying organic matter such as compost piles, rotting leaves, and damp soil. These locations provide an ideal environment for gnats to lay their eggs and development of larvae. Indoors, gnats can be attracted to overwatered houseplants, damp areas in the kitchen, or any place with standing water.Visit our Species, Control, and DIY Guide sections for additional resources on gnat and ways to tackle a gnat infestation.Gnats come from environments that provide them with food, moisture, and ideal breeding grounds.
