2. Bleach + Hot Water (To Kill Gnat Eggs)

In the bathroom, the best place where you can find gnats is the drainage system. Therefore, using gnat bug spray is not a very effective way to deal with them.

Bleach is able to kill them as well as their eggs.

But, it’s not necessary that bleach will eliminate all of them along with their eggs because maybe they’re breeding deep inside the drainage system.

Pour the bleach into the drains, and allow it to settle. After 30 minutes, pour boiling water into the drains to wash the bleach & to kill the remaining gnats & eggs.

You can also dilute the bleach by adding some water to it.

Some people also got success using Ammonia instead of bleach.

When using these liquids make sure you wear gloves & mask for your protection.

Warning: Don’t mix Ammonia and bleach. Mixing them will the toxic fumes can be hazardous to health.

So, you can use bleach to kill their eggs in the drainage system, but only bleach can’t eliminate all the fungus gnats in the bathroom. For killing all the flying gnats in your bathroom, you’ll also need these methods given below.

A big reason why you are seeing gnats in your shower is because there is:

  • stagnant water
  • attractive scents that invite them to stay

Stagnant Water

You must ameliorate this effect by running shower water all over the contained area and draining it out.

If you have a shower that is barely ever used, go there and use the shower head for a few seconds to let it flow through the drain. Add salt, vinegar, baking soda to the drain and wash it all down with shower water

Gnats Love Sweets Scents

You may have to think twice about some items in the shower or bathroom that are sweet smelling or appealing to gnats such as:

  • fruity soap
  • houseplants
  • garbage
  • food residue

Why Do I Have Gnats in My Bathroom?

Gnats are attracted to moisture and damp spaces. The bathroom is a perfect breeding ground for gnats. The area is warm, moist and may even contain attractive scents coming from fruity soaps, garbage and even houseplants.

They will come out from vents and drains where they enjoy reproducing in such a moist setting. Leaky pipes and condensation around the windows are also appealing areas for gnats to dwell and breed.

You can dehumidify your bathroom and spray the area with vinegar after your shower or bath. Gnats also get trapped in bowls filled with water, sugar and dish soap. Leave 1-3 bowls in the bathroom to lure them in.

Why Have I Got Gnats Around Toilet?

Toilets carry bacteria and remnants of food that we don’t wish to think of or see anymore. Unfortunately, gnats smell, see or become attracted the decomposing food or any foul remainders that may linger in and around the toilet.

The toilet bowl itself is also stagnant water if not flushed recently. Use bleach, toilet bowl cleaner, vinegar or dish soap to get rid of gnats who are lingering in this space.

The inside of a toilet must be a clean place that we regularly soil and flush away. The space around the toilet needs to be dry and cleaned with soap, vinegar or bleach. 

How to Get Rid of Gnats in Bathroom Drain

Gnats and other insects may find their way in your bathroom drain. This is a breeding ground and highway for tiny pests that may enter or exit your home.

They may also wish to lay eggs in crevices located near or within the drain:

  1. Sprinkle salt and baking soda
  2. Spray with vinegar
  3. Drop in a tablespoon of dish soap
  4. Let the drain sit with this solution for up to 5 minutes
  5. Begin to allow the water to flow it all down. 

Do this once a month or more often when you see gnats in your drain. Also remember that if you aren’t using this drain for quite some time, gnats are more likely to gather there.

This means you should use the shower head for a few seconds per week to allow some water to flow down the drain. 

Final Words

I suggest that you use bleach for the treatment of the drainage system. Along with that, for killing the adult flying gnats, you can use the Hafer Sticky Trap, Apple Cider Vinegar Trap, or the GLOUE Bug Zapper.
