While they may not harm humans, they can be a nuisance and an eyesore. So is there any solution to get rid of drain worms in your shower?

You must kill all the larvae under your drain to completely eliminate these worms. To do this, use bleach, baking soda & vinegar solution, hot water, or a drain cleaner.

How Do You Get Rid of Drain Worm or Fly Larvae in a Shower?

How Do You Get Rid of Drain Worm or Fly Larvae in a Shower?

Getting rid of drain worms is easy, provided you know the right approach. Additionally, more than one solution can help you eliminate these pesky creatures. Here are some of the most effective methods to remove drain fly larvae from your shower:


remove drain worms with bleach

Bleach is a common household item that is well-associated with cleaning, especially in the bathroom and kitchen. You can use it to kill the larvae in your drain. Pour a cup of bleach down the drain and let it sit for a few hours before rinsing the area with hot water.

Baking Soda & Vinegar Solution

Using baking soda and vinegar together makes an effective solution to kill drain worms larvae. First, take 1/2 cup of baking soda mixed with salt. Pour it down the drain, followed by 1/2 cup of white vinegar. Since vinegar reacts to baking soda, it will create a fizz. However, don’t worry; it is likely not harmful.

Leave this solution in your drain for some time. We recommend leaving it like this overnight. Then rinse the drain with hot water, and you’re all done. You can repeat this process every few weeks to prevent drain worms from returning.

Hot Water

Hot water can dissolve mineral deposits. Pouring it down the drain is another simple yet effective way of getting rid of drain worm eggs and larvae. You don’t need extra ingredients; just fill a bucket with hot water and pour it directly into your clogged drains.

Or you can also turn your shower on full blast and allow the hot water to run for a few minutes. The hot water will help break down bacteria and larvae in the drain, washing them away with water flow.

NOTE: Do not pour boiling hot water, as it will likely damage your drain pipes or other plumbing fixtures.

Drain Cleaners

Using a store-bought drain cleaner is also an effective way to get rid of drain worms in your shower. However, it is essential to be careful when using these cleaners, as they can be caustic and may damage plumbing fixtures if misused.

We recommend using organic, biodegradable drain cleaners that don’t contain harsh chemicals. These are safer for your pipes, as well as the environment. Follow all instructions on the packaging, and you should have no problem removing drain worms in your bathroom.

Clean the Drain Pipe With Brush

Cleaning your pipes or holes with a brush is another simple option to remove drain worms. This method also helps clean away any gunk that may have built up in the pipe and prevent future clogs.

Start by unscrewing the drain cover or filter, then take a pipe brush and insert it into the drain hole. Move it around in a circular motion to scrub away dirt, grime, and larvae. Once done, reinstall the filter or cover it and flush it with hot water or any of the above-mentioned solutions.

Use a Plumbing Snake

You must already know of a plumbing snake, right? This is the best way to get rid of clogged drains and any blockages that might be causing your shower drain to become a breeding ground for larvae.

Insert the plumbing snake into the drain and turn it clockwise until you’ve gone through the pipe’s curves. When finished, flush the area with hot water. This will remove any debris, gunk, and larvae blocking your drain.

What Causes Drain Worms in the Shower?

Do you often see tiny black or red worms near your shower drain? These are likely drain flies, sometimes called filter flies or sewer gnats. They lay their eggs in drains, sinks, and other moist places, hatching them into larvae (drain worms) that feed on organic matter living in the gunk at the bottom of your plughole.

The #1 reason why drain worms appear in showers is because of a clogged drain. As water accumulates, it creates a perfect environment for larvae to breed. Hence, the best way to protect your home from drain worms is to ensure your drains are regularly cleaned and unclogged.

How Do You Prevent Worms From Coming up the Drain?

Since drain worm infestation is usually caused by a buildup of dirt, grime, and other debris, keeping your pipes clean is essential. In addition, you should also be sure to inspect any openings or cracks in the walls near the shower, as these can provide an entry point for drain worms.

Below are some ways you can use to prevent the infestation of drain worms in the shower:

  • Fix Plumbing Issues – Ensure your plumbing is up-to-date and running properly. If you need help with how to do it, you can hire a professional to help you. In addition, regular drain cleaning will also allow you to prevent future drain problems.
  • Use Mineral Oil to Prevent Infestation – Mineral oil can help prevent drain worms from coming back in the shower. Pour a cup of mineral oil down your shower drain every month to create a barrier between the larvae and any debris that may accumulate.
  • Remove Moisture – Moisture and humidity encourage larvae growth, so ensure you reduce room moisture by using a dehumidifier or fan. Additionally, ensure there is no leaky shower or taps.
  • Install a Drain Filter – A drain filter will trap any debris and prevent it from clogging up your pipes while also stopping larvae from entering the drain.
  • Seal Crevices – Check the walls and cracks near your shower to ensure no openings. Seal any openings with caulk or epoxy resin to prevent flies larvae from entering.
  • Use Insecticides – Insecticides can help kill drain worms and other pests hiding in the sewage system. Use them as a last resort, however – they are toxic to humans and animals.

Are Drain Worms Harmful?

Drain worms are not harmful to humans but can damage your plumbing system if left unchecked. The worms feed on the gunk and residue that builds up in your pipes over time, clogging them up and leading to costly repairs.

In addition, the worms can also breed and lay eggs in your pipes, causing even more blockages. Moreover, when the larvae mature into flies, they can spread bacteria and other harmful pathogens into your home.

Therefore, it’s best to take preventive measures as soon as you suspect a problem and get rid of the larvae before it causes too much damage to your plumbing system.

How Do I Know Where Drain Flies Coming From?

If you have a drain fly infestation, there are several signs you can look for to determine the source of the problem. These include:

  • A musty smell coming from drains or other plumbing fixtures
  • Clogged drains with standing water
  • Gunk and residue around faucets, showers, and toilets
  • Pests or larvae near the drains
  • Signs of infestation in other parts of your home, such as small flies hovering around windows and doors
TIP: If unsure which shower drain is infested, try the duct tape test. You can do this by placing duct tape over the drain and leaving it overnight. If the worms are present, they'll likely come out at night and stick to the duct tape.

How to Get Rid of Tiny Black Worms in the Sink?

Removing black worms in the sink requires identifying the source of the infestation. You can use white vinegar and mix it with hot water. Then pour it down the drain and let it sit for a few hours.

However, if the worms keep reappearing, you should call a plumber for an inspection to determine if any plumbing issues led to the problem.

Will Cold Weather Kill Drain Flies in a Shower Drain?

No, cold weather will not kill drain flies in a shower drain. Drain fly larvae require temperatures above 50 degrees Fahrenheit to survive, but they can remain dormant for long periods and emerge again when temperatures are warm enough.

Why Do Drain Flies Keep Coming Back?

Drain flies keep returning because they can reproduce quickly and lay eggs in the water that accumulates in your pipes. To prevent them from returning, you’ll need to reduce moisture in the area and block off any potential entry points. Furthermore, regular drain cleaning and sealing of cracks may also be necessary.

Do Plumbers Deal With Drain Flies or Worms?

Yes, plumbers often deal with drain flies and worms. They can help diagnose the problem and eliminate the pests by using insecticides or installing a drain filter. Additionally, they may also be able to identify any plumbing problems that may have caused the infestation in the first place.

Will Bleach Kill Drain Flies?

Yes, bleach can be used to kill drain worms and flies. Pour a cup of bleach down the shower or sink drains and flush it with hot water. However, pour slowly, as too much bleach can damage your pipes. Additionally, use gloves and safety goggles for protection when using bleach.
