Gnats in your house are typically attracted by a few common factors: overripe or rotting fruits and vegetables, sweet or fermented liquids, and excess moisture. They are often found around kitchens and dining areas due to food residue, or near houseplants with damp soil, which provide breeding grounds. Gnats may also come from outdoor sources entering through open doors, windows, or small gaps, and they thrive in moist environments like sinks, drains, trash cans, and overwatered plants. Key reasons why gnats infest houses:
- Overripe or rotting fruits and vegetables emit aromas that gnats are drawn to for laying eggs.
- Moisture from wet soil in potted plants, leaky pipes, or damp areas supports larval development.
- Fermented or sugary liquids in drinks, spills, or sinks attract adult gnats.
- Decaying organic matter in trash bins or clogged drains can be breeding sites.
To prevent infestations, it's important to remove these attractants, keep food sealed or refrigerated, maintain dryness in plant soil and household areas, clean drains regularly, and manage garbage properly. Sealing entry points and using traps can also help control gnat populations indoors.
