If black worms have taken up residence in your bathroom, there are numerous approaches to banish them for good. Here is a compilation of the most successful strategies:

1. Reducing Moisture In The Air


A simple and effective solution is reducing moisture levels in the air. In order to accomplish this, Ventilation fans are highly recommended for showers and baths to remove excess steam from the room.

Always remember: Cracking open a window can make all the difference! Not only will this help reduce the worm population, but it’ll also keep your space much more pleasant overall. You can even get a dehumidifier if things are terrible in terms of humidity.

2. Cleaning All Bathroom Surfaces With Bleach

Simply mix a solution of bleach and water, and wipe down all surfaces in your bathroom with a clean cloth or sponge.

3. Using Insecticide

For an extra-powerful solution, consider using a spray insecticide to get rid of black worms. These sprays are typically made with non-toxic strong chemicals that can be very effective at killing black worms and other pests in your bathroom. 

Just be sure to follow the instructions on the label carefully, and avoid getting any of the sprays onto yourself or your skin.

Since the black worms need that biological gunk to survive. It’s a good idea to use an enzyme cleaner on your drains. These cleaners will break down that gunk and eliminate the worms’ food source.

They’re also very convenient because you can pour them into the drain every time you do laundry or take a shower!

5. Pour Hot Water into the Drains 

If you’re looking to quickly get rid of those pesky black worms, adopting a continuous hot-water routine is key. Pour steaming water into your drains for at least 5 to 12 minutes every day.

This will exterminate any existing worms and discourage future growth. To maintain an ongoing worm-free bathroom environment, repeat the process as desired.

6. Baking Soda and White Vinegar
