Why Do I Have Gnats in my House?
Presence of Rotten Fruits or Vegetables
If you have extremely small, light brown flies in your kitchen, it’s most probable they are fruit flies. They possess peculiar red eyes by which they can be distinguished from other flies and as the name goes, they are attracted to ripened or rotten fruits and vegetables.
Typically, they get attracted to non-refrigerated produce: tomatoes, grapes, onions, potatoes, bananas. Fruit flies normally appear in larger numbers during late summer and early fall as they are known to infest newly harvested fruit and vegetables.
Also, your yard can contain a variety of fruits and vegetables that attract gnats, but gnats in the interior of the house tend to be a greater problem.
Fruit flies lay eggs on the surface of rotting fruits, vegetables or other organic materials, which they feed on.
This causes the removal of an infestation to be tricky as larvae may continue to hatch in fermenting fruit even with the extermination of the adult population. The best preventive measure would be to keep produce in the refrigerator and to get rid of rotting fruits and vegetables.
When you notice small dark flies in the house most especially during the fall and winter months, they’re likely to be Fungus gnats. They have long legs and antennae; this gives them a mosquito-like appearance.
Often times the presence of these fungus gnats is noticed because they try to fly into a person’s nose, mouth or eyes as they are attracted to moisture. Adult Fungus gnats lay eggs in the soil where soil conditions are moist and decaying matter is present to feed upon.
The eggs of gnats hatch in the soil, and the larvae live and feed on algae, fungi and other decaying materials found in house plants. If you tend to overwater your plants, there is a high chance of fungus gnat infestation because they breed in overly moist potting mixes.
To guard against this infestation, you should ensure that the top 1-2 inches of the soil in your houseplants dry out before you water them.
Some gnats have a direct connection to broken sewer line whether on the exterior or interior of the house. These gnats may also appear around a kitchen sink with an overflowing garbage disposal.
When you find these gnats around your kitchen sink or around broken pipes, they are probably Drain Flies. Drain flies live in plumbing drains and sewage systems.
They have a dark color, furry appearance and they are moth-like in their appearance. They also look like fruit flies but you can tell them apart from fruit flies because they don’t have red eyes. Drain flies are drawn to sewage, bacteria and other organic materials that typically line drains and because of their small size, drain flies can pass through small pipe cracks and openings.
They have extremely fine water-repellant hairs covering their bodies, this makes them resistant to boiling water and it makes them difficult to drown. The eggs even are very resistant to chemical attacks and they can withstand periods of dehydration.
To get rid of drain flies in your home, make sure you clean drain traps and drain pipes regularly to remove whatever organic material that might gather in those areas. Regular cleaning of the drain pipes and drain traps eliminates the food source of these drain flies.
