Small Black Worms in Septic Tank – How to Get Rid of Them!

Spread the love

If you notice small worm-like creatures moving on their own in your toilet, they are most likely drain or sewer fly larvae or pupae. Except for a few minuscule exceptions, those are not parasites.

They live freely in the organic muck that accumulates in the toilet or septic system. If they’re in the toilet, you should thoroughly clean it and flush it on a regular basis. Nothing else is required.

I don’t have a septic system, but I believe that drain fly/sewer fly larvae are common in septic tanks. They contribute to the decomposit

ion of waste.

If you notice them entering your home via drains, use a septic-safe foaming drain cleaner.

What do Drain Worms Look Like?

Drain worms are extremely small worm-like creatures. These slender larvae are frequently discovered in toilets and showers. By infrequently using or cleaning a sink, toilet, bathtub, or even the area beneath the washing machine, you effectively create a breeding ground for them.

In the bathroom, there are drain worms.

The reality is that various types of worms can appear in a shower. Fortunately, drain worms in showers are easily distinguished from other types due to their small size and black color. This also explains why they are called black worms.

Are Drain Worms Poisonous?

Drain worms are not dangerous in and of themselves. They are present to indicate that your drain is clogged with decaying organic matter. They live in all this filth and scavenge for food.

If you’re wondering if drain flies are harmful, the answer is that it depends. They can be harmful if they land on your food or other items that you touch or place in your mouth. Given that they eat the same dirt as the larvae, they have the potential to transmit a large number of bacteria this way.

What Causes Drain Worms?

Drain worms typically appear after a lengthy vacation, usually within 48 hours. Meanwhile, no drains have been cleaned, and there may be some stagnant water lingering inside or outside the house.

By being absent from home, you allow time for wet spots to develop into ideal breeding grounds for dry flies.

Or perhaps there is a leak in the wall or some water beneath the washing machine that you are unaware of. In either case, there is some standing shallow water. For drain flies, such standing water is equivalent to an entire McDonald’s.

Fly larvae will live and thrive in it, gradually growing in size until they mature into flies and annoy you in that form.

Why are there Worms in My Shower?

Although drain worms are more likely to be found in the toilet or bathtub, they can also be found in the shower.

The most common reason for these larvae to emerge from the shower drain is that it has been inactive for an extended period of time.

By not using it, all that wet slime has time to become denser and more gelatinous, containing all the bacteria and microorganisms.

It becomes saturated with organic matter (a gelatinous film) and eventually becomes a breeding ground for drain flies.

The larvae will eventually appear around the drain as they hatch and grow.

How do You get Rid of Drain Worms?

The first step is to determine whether or not the drain is clogged. If it is, that is the first issue you must address. To remove them, the simplest method is to pour boiling water down the drain. That boiling water will kill the majority of them.

Pour some white vinegar into the drain to kill the remaining worms. Additionally, you can purchase a variety of highly effective drain cleaners. Some of them can cause damage to pipes, so be sure to purchase the correct one.

The third step is to inspect the interior and exterior of the house for additional wet and dirty areas. Shallow, stagnant waters provide an ideal habitat for these larvae and their parents. After a thorough cleaning, you can significantly reduce the likelihood of them reappearing.

Consider the following products to eliminate drain worms:

Once you’ve located them, you must act quickly. It turns out that using the method described previously, you can eliminate them in a matter of hours.

Will Bleach Kill Drain Worms?

At some point, it became widely believed that pouring bleach down the drain eliminates drain flies.

Regrettably, these sewer flies are not easily killed. Pouring it down the bathroom sink may help in some rare instances, but there are far more effective methods.

If done correctly, the method described above will eliminate all worms simultaneously. The issue with bleach is that the majority of eggs and larvae do not float to the surface.

That bleach evaporates so quickly that it has no time to wreak havoc on that entire layer of gelatinous slime.

To dissolve all that organic matter, a large amount of bleach would be required. Additionally, bleach is a well-known corrosive. If you have older pipes running beneath that drain, this will corrode them and is not recommended for septic tanks.
