The Most Effective Ways To Get Rid Of Drain Flies

  |   Flies   |   No comment

If you have seen small insects hovering around stagnant water or open drains on your property, they are drain flies. These are actually moth flies that got their name from constantly flying around drains. This is a very small fly and most people mistake it for a fruit fly; but it doesn’t really cause any real damage. However, these flies breed very rapidly and their populations can grow at an alarming pace, which is how it doesn’t take long for them to become a pest around the house.


Identifying drain flies

While you would surely need a magnifying glass to see all the characteristics of these flies, you may be able to notice some of the following ones only with your naked eyes:

  • 1/5″ to 1/10″ in length
  • Body & wings are covered with long hair that make it look moth-like and fuzzy
  • It has a black to dark grey coloured body with lighter-coloured wings.
  • It has long and curve antennae
  • It’s also commonly referred to as a filter fly, sewage fly or a drain fly

This fly can’t really fly very well and it can manage to wing it only for a few feet each time it tries. This is why it’s easily identifiable as it makes abrupt, hopping flights in case it is disturbed and won’t really fly for a longer distance. Due to this, it is generally found near the main source.

However since it is so small and light, it can easily be carried by the wind out of a sewage plant or drain into your home which is a kilometre away. And because of its tiny size, it is also very easily able to get through any standard screens.


Where drain flies are typically found

Drain flies feed on decaying organic matter in standing water, and moss and they also feed on flower nectar. These flies are very adaptable and can live and breed in various types of environments if they find week-old standing water or organic matter, and tend to be more active in the evening hours. Places where these flies are more likely to be found include:

In homes you can find these flies in on as well as around:

  • Floor drains, sink drains
  • Garages, showers, and basements
  • Walls adjacent to drains, and infrequently used toilets
  • Unwashed and unclean garbage disposals
  • Sides of showers
  • Loose tiling where moisture accumulates
  • Others

Outdoors, around your home:

  • In/around compost piles
  • Damaged septic lines
  • Garbage areas
  • Standing water (shallow polluted ponds, tree holes, rain barrels)

In natural surroundings:

In and around polluted, shallow water/compost/high-moisture organic material


The nuisance pests

While these flies are in no way dangerous as they don’t transmit diseases or bite, they breed in filth; and they create very unhygienic conditions in your home. As mentioned earlier, they are fast breeders; the female of the species can lay between 10-200 eggs at one time, and it takes only two days for these eggs to hatch. Which means, it doesn’t take long for the drain flies’ population to increase exponentially within a very short span of time and often, it seems like they have appeared out of nowhere.

One of the simplest ways to prevent these flies from breeding around your home is to make sure there is no stagnant water or open drains anywhere in and around your home.
