2. Where Gnats Come From

Fruit flies, drain flies, and fungus gnats invade your home from different places. Each type of gnat forms and lays eggs in common places in your house that are hospitable to it. Fruit flies come from fruit -- in particularly overripe or rotting fruit -- as the creature's name implies. Drain flies dwell in grime and standing water from drain pipes. Fungus gnats are most commonly found in the moist soil of houseplants. Now that you know how to identify the gnats in your home and where they come from, you can use the following methods to eradicate them from your living space.
