Drain flies or sink moths are fuzzy, pesky nuisance insects that live and breed in the moist, organic matter of kitchen and bathroom drains. Less than five millimeters long, this grey or tan fly ironically doesn’t fly well at all, but rather flits in jerky fits and bouts and can often be spotted resting on the walls surrounding a sink.

Sink moths often show up at sinks that aren’t used frequently or are stagnant. They often appear when you get home from a vacation, though they can be just as troublesome in kitchen or bathroom sinks that are used frequently.

Traveling And Swarming In Drain Flies Vs Fruit Flies

Another easy way to differentiate between drain flies and fruit flies is to check whether theyre swarming and traveling together or not.

Drain flies are more often found together, especially when theres a lot of waste. However, fruit flies tend to travel alone unless theres a big feast for them all to eat.

On top of this, fruit flies will almost always be found around fruit and vegetables, which are decaying, whereas drain flies arent as picky. In fact, its common to see drain flies anywhere theres an organic buildup of food.

But one of the biggest differentiators is how light it is. Fruit flies are active during the day and will fly around at any time. Whereas drain flies tend to be a lot less active any time its light and prefer flying around in the dark.

Consult With Your Plumber

Cracks or leaks in your sewage pipes are a great way to attract drain flies and other pests. Ask your plumber to test the integrity of your drain system.

They will likely run a fluorescent dye test during which they flush dye down your toilet. If that color appears in the sump system or other places it shouldnt, you have a problem. Your plumber can help repair your system, leaving your home in safer and better condition.

Rotten Food And Fruit

Even the smallest rotten piece of produce welcomes flies to lay hundreds of eggs at a time.

Small pieces of old food can end up inside a sink drain, on the outside of a garbage can, or at the bottom of a fruit bowl, so be sure to examine these spots. Fruit flies are also attracted to other common sweet and sticky spots in your kitchen, even if you simply missed some spilled fruit juice on the counter when wiping it up.

How Do You Get Rid Of Fruit Flies Coming From Your Drains

Treehugger / Alexandra Cristina Nakamura

To rid your pipes of drain flies without using pesticides or harsh chemicals like bleach or drain cleaner, try these methods:

  • Use a metal pipe brush and push it through the pipe back and forth as far as it will allow followed by lots of boiling water.
  • Trap flies by setting a bowl of equal parts sugar, water and white vinegar with a 5-10 drops of liquid dish soap on the counter next to the sink overnight. Flies will be attracted to the fragrant liquid and drown.
  • Boil a pot of water and pour it down the drain 1-2 times daily for a week.
  • Pour ½ cup of salt, ½ cup of baking soda and 1 cup of vinegar down the drain and allow to sit overnight. Follow with a pot of boiling water in the morning.
  • Pour ¼ cup of apple cider vinegar into a glass and cover tightly with plastic wrap. Poke holes in the plastic wrap with a fork and place the glass next to the sink. Flies will be attracted to the cider vinegar and work their way inside and drown.
  • A natural product called Bio-Clean is a nontoxic, environmentally friendly drain cleaner that eats away at organic matter blocking your drain. Once the drain is cleaned, the flies will start to disappear.
  • Once drain flies are gone, keep sink drains cleaned weekly by pouring ½ cup of baking soda down the drain followed by lots of warm water, or pour a cup of white vinegar down the drain weekly and let it sit 30 minutes before flushing with water. Squeeze half a fresh lemon down the drain for odor control.

    Will Bleach Kill Fruit Flies In Drains

    Bleach is commonly used to try to get rid of fruit flies in drains, but many experts present these methods as ineffective. It is true that fruit flies do not tolerate bleach, and ingesting it will kill them. But the reason the flies are in the drains in the first place is because of the thick grime coating the pipes, serving as both a breeding ground and a source of food and moisture.

    When bleach and other chemicals are poured into the drain, the flies and their larvae will detect the scent and burrow into the gunky debris, shielding themselves from the harsh chemicals. So while it might kill a few individuals, and get rid of quite a few eggs, it wont do much to get rid of them in large numbers, or long-term.

Always use trash bags and throw the trash bag away at the end of the day. If the bag isn’t full and you don’t want to toss it, at least make sure it’s always covered.
    • Wipe down any fruit or vegetables ripening on your countertops. To wipe the fruit, use a clean towel that you have dipped in slightly soapy water. After wiping, rinse and dry the fruit. You can also use a combination of water and apple cider vinegar in place of soap to wipe the fruit .
    • Put the fruit and veggies in an empty paper bag. This allows them to continue to ripen.

    Ways To Get Rid Of Fruit Flies

    The sooner you try to stop the spread of the infestation, the easier it will be to control. To get rid of fruit flies there are plenty of natural and chemical-based ways to get rid of them. Either option is easy to get started relatively quickly as many of the natural tactics use products already in your pantry.

    Life Cycle Of A Fruit Fly

    The common fruit fly is known for its ability to reproduce rapidly. Larvae of fruit flies develop in moist areas where organic material and standing water are present. The entire life cycle lasts 25 days or more depending on the environmental conditions and the availability of food.

    Like other fly species, fruit flies experience a four-stage life cycle: beginning as eggs, they undergo larval and pupal stages before emerging as adults. The early life stages span approximately a few days and fruit flies can complete their development in as little as week in ideal temperature conditions. Adult fruit flies can live up to 30 days.

    Baking soda is another effective household drain cleaner. You can mix a half cup of baking soda with a half cup of salt, half cup of lemon juice, or a half cup of vinegar for an environmentally friendly disinfecting option.

If you have a drain that frequently goes days or weeks without use, close it up with a stopper so that drain flies cannot find a home there in the meantime.

    Outside of your drains, keep an eye out for standing water in other areas in and around your home. Never leave dirty mops in buckets of water and be sure you have a healthy septic system.
