Drain flies aren’t dangerous, but that doesn’t mean you’ll need to allow your home to become a breeding ground for them!

And believe us when we say this: although just 1/8th of an inch in size, these flies can multiply like anything. The average drain fly lays around 30-100 eggs at a time at just two days old! So if you let them, they’ll quickly take over your floor drains, septic tanks, and pipes.

Drain Flies

This can lead to multiple plumbing problems, such as blocked drains and nasty smells. That’s why we’ve created this guide on how to get rid of drain flies for good so that you can take care of fly problems efficiently and effectively.

Where Do Drain Flies Come From Anyway?

Before we tell you the solution to the drain fly infestation problem, let’s take a peek at where drain flies Australia come from. Drain flies (sink flies or moth flies) thrive in shallow, stagnant water areas. These creatures love moisture and, like fruit flies, can be found near decaying food, stagnant floor drains, or kitchen sinks.

They like to nest around areas that are not used that often, like workshop sinks or basements. You can also find them around septic tanks and sewers. However, they might even pop up in clean pipes and around well-maintained drains, which can attract drain flies if located near food sources or organic matter.

As we mentioned, although they are not directly harmful, they do indicate that your kitchen, bathroom, or pipes need a deep cleaning. With that in mind, let’s see how we can tackle the drain fly problem and prevent drain flies from returning.

With that settled, let’s see how to get rid of drain flies!

Stepwise Procedure To Get Rid Of Drain Flies

If you’ve discovered drain flies in your home, we recommend acting immediately. And if you’re the DIY type, follow the steps outlined below to get rid of drain fly larvae and full-grown drain flies for good.

Step 1: Unclog The Affected Drains

The first step in how to get rid of drain flies deals...well…with the drains. Drain flies love it when they find a slow-moving or clogged drain; that’s where they like to settle down and multiply. So, the first thing you need to do to get rid of drain flies is unclogged drains around which you find the flies lurking.

Step 2: Get To Cleaning Them

Once you’ve unclogged your drains by removing all the nasty decomposing gunk, it’s time to move on to the next step in permanently getting rid of drain flies. And that’s cleaning the drainpipes; the simplest method is to pour boiling hot water carefully down the drain.

Along with pouring warm water, you can also use chemical cleaners and sprays to clean the drains. If you still find food or animal waste stuck in the drain, use a wire brush or drain snake to complete the job thoroughly. Just remember to be careful so that you don’t damage the pipes.

Step 3: Tend To The U-Trap

It would help if you also cleaned the U-trap with the drains and pipes, as that’s where sewer flies and filter flies will congregate. You might also find drain fly eggs in the U-trap, so clean it properly. Everyday household items that can be used to clean these fixtures are baking soda or apple cider vinegar. However, apple cider vinegar can tackle just adult flies and trap them.

To tackle the larvae as well, you need to apply a solution of baking soda and vinegar. Just combine equal amounts of salt, baking soda, and vinegar and use the mixture to clean the U-trap. This will resolve drain fly issues by killing the larvae, thus nipping drain fly infestations in the bud.

Step 4: Apply Enzyme Cleaners

If you’re looking for something stronger to tackle the drain fly problem, we recommend using chemical cleaners such as Drano or Bio-Clean. However, be careful while using these products and ensure they are safe with your pipes and drains.

Step 5: Rinse Using Warm Water

As the final step, rinse your pipes using warm water to make sure there are no traces of the chemicals you’ve used for cleaning the drains. This method will also remove small flies if any have escaped by chance.

Following the above steps should ensure that drain flies in your home have been taken care of. But if it doesn’t work and leaves you with a drain fly infestation, it’s time to stop Googling about how to kill drain flies and call in the professionals.

These experts have the know-how to eliminate these nuisances with six legs. Whether it’s septic systems or outdoor sinks, the drain fly issue will be resolved without you needing to worry about it.

How To Stop Drain Flies From Getting In Your Home

As mentioned, drain flies thrive near standing water, bathroom drains, stagnant waters, and dirty mops. So, to prevent drain flies from entering your home, you can take the following actions:

  • Keep your house clean and tidy, with periodic removal of organic debris from drains
  • Find and plug small cracks or openings near areas with organic material
  • Use a pipe brush and white vinegar/baking soda mixture to clean drain pipes
  • Never keep dirty mops near drains or in buckets; try to dry them before storage
  • Get a pest control professional done once every year at least
  • Periodically lure flies away using apple cider vinegar and plastic wrap traps
  • Maintain a hygienic septic system

Following the above steps will ensure that pests such as drain flies and sewer gnats don’t make your home their safe haven.

Eliminate Drain Flies for Good!

Drain flies can often gather around a drain overnight, but the problem isn’t enough to cause panic. No one finds drain flies harmful, and to kill drain flies, you can use ordinary household stuff like dish soap, boiling water, and a metal pipe brush. Using a chemical drain cleaner also takes care of sewer flies rather well.

Whatever methods you use to get rid of drain flies, remember one thing: do not let standing water gather in your home. Stagnant water attracts drain flies and entices them to lay eggs. So, this is the one factor you must remember if you want to get rid of drain flies.

We hope you can put the information in this guide on how to get rid of drain flies in Melbourne to good use. And if you’re still unsure, do think about hiring professional help.
