Identifying the Source of Gnats in the Kitchen

Identifying the main source of your gnat infestation is the first step in learning how to get rid of gnats in kitchen spaces. You can effectively reduce or completely eliminate the gnat population in your kitchen by eliminating food and other sources. The most common breeding grounds for gnats include:

  • Light fixtures: fruit fly or gnat clusters are drawn to light sources and will be found near your light fixtures or windows.
  • Fruits and vegetables: overripe fruit and rotting vegetables attract gnats. Fruit flies thrive off these food sources so it is best to throw them away as soon as possible.
  • Damp, still water: when you have standing water or still water, gnats will breed in these areas. For instance, moist environments like bowls of water, the sink bowl, or drains are the usual breeding grounds for fruit flies.
  • Waste: dirty dishes and garbage are another food source for this insect.
  • The outdoors: gnats may have found their way into your home because of the compost, garden, or connecting rooms.
  • Forgotten food: food containers left open, crumbs and spilled drinks can also attract gnats. Keep all of your food and drinks stored away in air-tight containers or plastic bags. Also, make sure to clean up food preparation areas and the kitchen counter or dining table as soon as possible.
  • Houseplants: fungus gnats can breed in the soil of your houseplants and infest your kitchen.

Keeping your kitchen clean on a regular basis and being mindful of food preparation and disposal areas are the best way to protect your home from a gnat infestation.
