Will Vinegar Get Rid Of Drain Flies

Vinegar is a great way to get rid of drain flies because it will kill drain fly larvae and dislodge leftover foods that make great breeding grounds. Drain flies are attracted to dirty, moist environments. They must have nutrients nearby to grow. If you use white vinegar to dislodge food debris, you are less likely to attract adult drain flies who will lay larvae.

Stagnant water is a leading cause of drain flies. Boil water and pour it down your drain to remove build-up and prevent standing water so flies are not attracted to your sink.

What Causes Drain Flies?

Drain flies are attracted to dirty environments. Standing water and an unclean environment are among the most common causes of drain fly infestations. These cause drain flies because they are damp environments with plenty of nearby nutrients.

Pay attention to your hygiene, which can attract drain flies if it is ill-kept. Personal hygiene is essential for keeping drain flies away from your home. 

Stagnant Water

Stagnant water is the most common cause of drain flies. They are attracted to the non-sterile environment. They are most commonly found around leftover food sources and bacteria, so they prefer sinks full of dirty dishes.

Poor Body Hygiene

Poor body hygiene will attract drain flies because of foul odor and the dampness from body sweat. They will not lay eggs on the human body. However, the smell of body odor and the results of poor hygiene often attract this insect. Examples of poor hygiene might include excess trash lying around your home, open water or drink bottles, and other forms of debris that make great nesting grounds for the drain fly.

Lack of Running Water

Drain flies are more likely to be attracted to areas lacking running water. If you can find somewhere with running water, it is better at keeping drain flies away. If you have a sink that does not work correctly, hire a plumber to investigate the issue immediately, so drain flies do not lay eggs in your pipes.


Outdoor sinks are much more accessible to drain flies than indoor sinks. Therefore, you are much more likely to have drain flies in outdoor drains than inside your home. To prevent drain flies from nesting inside your outdoor drain, regularly use a white vinegar solution at least twice a month.

Does White Vinegar Kill Drain Flies?

White vinegar mixtures can kill drain flies. To use white vinegar, you must use the right combination, or else it will not dissipate the larvae and dislodge debris inside your drain.

Combine a vinegar mixture with salt, baking soda, and water, then pour it down the infested drain. Follow this by pouring a medium-size pot of boiling water down the drain. Repeat the process at least once or twice weekly until the infestation has been eradicated.

What Kind of Vinegar Kills Drain Flies?

White vinegar is the best vinegar for killing drain flies because you may use it as a solution to remove debris and deter drain flies from laying eggs in the drain. In contrast, you can use apple cider vinegar to attract drain flies and trap them inside a bowl. Apple cider vinegar is sweet, making it a good food source for adult drain flies.

How To Get Rid Of Drain Flies Using Vinegar

You can remove drain flies and their larvae by using a vinegar solution. A white vinegar, water, and baking soda mixture will kill drain flies if you pour it into your drain and then follow it with boiling water. The vinegar-based combination kills the larvae, thus preventing them from hatching.

It would help if you got rid of drain flies when they are still larvae, or they might hatch into adult drain flies.

Use a Vinegar Mixture

Use a white vinegar-based solution to clean your drain, pour it down the drain, or use it as a cleaning solution to clean the basin. It will kill the larvae in your drain and remove all debris on the sides of your drain that might attract the flies. Washing the flies down the drain will keep them from hatching inside your home and reproducing.

Clean Your Sink Basin with Vinegar

After killing your larvae using a vinegar, salt, and water solution, cleaning the interior of your sink basin using your vinegar-based mixture is crucial. This solution will kill any larvae that might be laid in your sink, preventing them from growing into adult flies. Furthermore, a vinegar-based solution will remove debris from your sink, which is not a sustainable environment for drain flies.

Pour Vinegar Down the Drain

Pour your vinegar-based solution down your sink to kill drain fly larvae. Following this with boiling water will wash away the larvae and clean your sink simultaneously. By rinsing the larvae down the sink, you guarantee they will not grow to maturity inside your home.

Apple Cider Vinegar Trap

Use an apple cider vinegar trap to lure and trap adult drain flies. Drain flies are attracted to the sweet smell of apple cider vinegar. Once they smell the apple cider vinegar, they will be attracted to the sweet smell. Place plastic wrap with holes poked on top to trap the flies inside without letting them escape. 


White vinegar is excellent for removing the drain flies from your house. They can be highly pesky insects that hold many pathogens, dangerous to your health. By pouring a white vinegar solution down your drain, you can kill larvae before they hatch into adult flies that later continue the infestation inside your home by laying their own eggs.

When you clean your sink with vinegar, you are more likely to create an inhospitable environment for the flies. You will clean your drain of any leftover food and debris that might attract the drain flies, making it too clean for the flies. They will be less attracted to your home and less likely to breed in your drains. If you find yourself confronted with adult drain flies, experiment with apple cider vinegar to attract the flies and kill them.
