Are Drain Worms Harmful to Humans?

Worms and drain flies (adult stage) do not bite or transmit disease from one person to another. However, because they come from unclean areas such as toilets, shower drains, compost pits, and other locations with germs, they pose a food contamination risk.

How Did I Get Drain Worms? (The Typical Reasons Why)

Worms consume decaying organic matter, such as hair and skin cells. Dampness and standing water are their favorite places to be, especially in plumbing pipes and p-traps. Generally, most people visiting our website have an issue with their shower, bathroom, sink, or septic unit.

Standing water can also be a great breeding ground, which is why you may frequently see them in a home that has not been lived in for a while.

If drain worms start to appear, then you may need to clean your pipes; however, drain worms do not always signify unclean pipes. A plumbing problem, such as a pipe that is slowly leaking, will gradually fill with standing water, creating the perfect conditions for the worms to breed and multiply.

Can Drain Worms Be a Cause of an Unseen Plumbing Issue?

Drain flies are not always a sign of unclean drains. As we’ve seen previously, stagnant drains will do wonderfully, whether clean or dirty. Unless they’re unused drains, there will almost certainly be moisture and organic material in them. But, with that said, drain flies are more attracted to dirtier drains.

Furthermore, because pipe leaks produce suitable habitats for the drain fly, damp rooms in your house might provide ideal breeding and dwelling grounds. A crack in your home’s sanitary sewer may also be a sign of a more serious plumbing issue, such as a loss of water pressure or clogged pipes.

If you believe any of the above reasons is why you are experiencing drain worm infestation, you must take care of these plumbing issues as soon as possible. Pipe leaks and fractures in the sanitary sewer might grow over time, posing structural issues as well as health risks.

How to Check If I Have Drain worms?

Worms generally stay close to the drain. The flies, on the other hand, can go anywhere in the house. They’re also dangerous and can contribute to bronchial asthma in people with weakened immune systems. 

Where are Drain Fly Larvae Commonly Found?

Drain worms are generally found in drains, toilets, sinks, showers, under bottles, in air conditioner pipes, around trash bags, or in places where rainwater collects. They are prevalent in septic tanks, indicating a healthy tank!

How to Identify a Worm Infestation in Your Sewers or Toilet?

It is important to note that not all the worms in your bathroom or toilet are drain worms. Before seeking a solution to eliminate them, ensure you have identified the type of worm that you have.

That being said, if you have adult drain flies, that is a clear indication that there are larva present, and worms will undoubtedly follow. 

Covering your drains at night with double-sided tape in a space where drain flies are common or where you discovered worms would determine whether you have drain flies. 

How to Get Rid of Drain Worms

Drain worms are not just unpleasant to look at. They can be hazardous to your health, too, so eliminating them should be a priority. The best approach to eliminating these worms is starving them by taking away their food source and destroying their breeding grounds.

1. Check and Remove The Clog 

The first step is to see whether the drain is clogged in any manner. Pour a half gallon of water down the drain and watch how quickly it drains to determine if it’s blocked. If it takes too long to drain, you may have a blockage.

2. Use a Plunger to Remove Grime Trapped in the Drains

You may use a plunger to remove any grime trapped in the drain corners. This ensures that there is no more organic waste for the worms to feed on.

3. Unclog the Drain Filters

Filters are one of the most common places where the worms thrive. They’re the breeding ground for adult flies, so you should unclog them on a regular basis. Debris, grime, and hair must all be removed from the filters.

4. Clean the Pipes

Remove any sludge build-up by scrubbing the inside and outside of the drain pipes. Using a metal rod, clean the inside of the pipes removing any waste build-up, and rinse with boiling hot water after.

Drain worms do not like clean pipes as the food supply has been eliminated.. Starving them and eventually, they will either die or disappear in a matter of a couple of weeks. If you have an RV drain fly problem, remember that the procedure differs slightly.

5. Use a Plumbing Snake

You can use this gadget to clean pipes much deeper than some other devices. Insert the plumbing snake and twist it within the pipe, destroying the breeding grounds and proceed to remove the dirt.

6. Pour Hot Water into the Drains

Hot water destroys the organic material that accumulates on drains’ surfaces, causing the conditions in which worms thrive to be destroyed. Hot water also kills the worms directly, eliminating the problem at its source.

Avoid boiling water since it may fracture some materials. Drain cleaners are also not suggested, as they frequently damage pipes.

7. Use Enzyme Drain Cleaners

Enzymes or bacteria are used in enzyme cleaners to consume organic material in the pipes, eliminating breeding grounds. Enzyme drain cleaners work as a whole clog-removing solution. Apply the drain cleaners according to the directions for optimum results.

8. Use Baking Soda and White Vinegar

Similar to the bio-based cleansers previously discussed, these chemical compounds dissolve organic material, making it simpler to clean the drains. They also eliminate the worms.

9. Use Insecticide Where They Have Been Found

There are several insecticides on the market that eliminate these bugs, but we recommend using natural materials. You only need to spray the drains and filters with an insecticide to completely eliminate worms using this method.

How to Prevent Drain Worms

Once you have managed to rid your house of drain worms, there are a few things you can do to prevent the return of the little critters. Below are some of the most effective ways to prevent any future returns of drain worms.

1. Use Mineral Oil to Prevent Infestation

Mineral oil can be used for any drains that aren’t in use on a regular basis, as well as to prevent worms. It’s applied to the drain’s surfaces to keep adult flies from laying eggs there.

2. Reduce the Level of Humidity

Drain flies and worms love humid climates. Therefore, reducing the amount of moisture build-up in your kitchen, bathroom, or garage can help you control the situation. Open a window, use a dehumidifier, or install a ventilation system to reduce dampness.

3. Clean the Bathroom With Bleach

If you believe the adult flies have deposited eggs on the surrounding surfaces, clean them with bleach. The chemicals will destroy both the eggs and the worms hiding in the grout.

4. Remove Possible Breeding Areas

Drain worms may be entering the house from outside. Remove any stagnant filthy water from around your home or from filthy gutters to minimize the possibility of drain worms coming in. It’s a good idea to relocate any composting pile farther away and conceal it if you have one.

However, if the root cause of your drain worms is a plumbing problem (e.g., a leaking pipe or a fractured sewage system), they will return if these are not addressed first. So get all of your drains inspected to see whether any of them might be contributing to the infestation.

5. Seal Crevices

Because they like wet climates, drain worms and drain flies tend to congregate in the small wet spaces in the bathroom caused by damaged silicone or latex filling in the tiling. 

6. Kill the Adult Flies

If you eliminate the adult flies, you will be able to get rid of the worms. A good drain fly repellent is an effective product in eliminating flies. You can also use physical methods such as fly swats, sticky tapes, and traps to kill the flies.

Irrespective of the larvae in the pipes having been eliminated, adult flies may have laid additional eggs; therefore, they must be removed. Use an insecticide spray and fly traps to rid yourself of these pests—as well as other tactics to eliminate them.

7. Naturally Killing Flies

Natural methods you can use to remove flies include mixing apple cider vinegar with liquid dish soap in a cup or glass with cling film over it with a small hole as a trap.

8. Use an Insect Growth Regulator

An insect growth regulator will prevent the larvae from progressing to the next stage. The worms will ultimately perish, resulting in no adult flies being produced, which is the primary source of concern.

9. Routine Maintenance

The best way to prevent a problem like this from recurring is to prevent it in the first place! Clean all drains throughout your house by pouring half a cup of baking soda into each one, followed by white vinegar of an equal amount. Invade is a bio gel that can also be used.

Allow this mixture to sit for a few minutes in the pipes and do its work and then pour boiling hot water down the drain to rinse the pipes. Ensure to irrigate drains that are used less frequently, such as once or twice a week, and maintain your septic system.
