We are going to describe another natural remedy to kill soil gnats, which is mainly in larval stage and eggs.
The method is very simple in addition to some precaution to increase efficiency level.
Hydrogen peroxide is the simplest peroxide (a compound with an oxygen-oxygen bond) and finds use as a strong oxidizer, bleaching agent and disinfectant. Concentrated hydrogen peroxide, or ‘high-test peroxide’, is a reactive oxygen species and has been used as a propellant in rocketry.
Moreover, Hydrogen peroxide is a simple home remedy to kill nats larvae and destroy knats eggs in seconds, hydrogen peroxide has a powerful effervescence which is a results of chemical reaction with the soil components including gnats stages.
How to get rid of soil fungus gnats the right way?
Once the soil is dry, mix 1 part hydrogen peroxide (H2O2) solution with 4 parts water. Use 3% solution, which you can find in any drug store or in the hygiene/medicine aisle of a chain grocery store.
You can use a stronger solution if you change the water mixture appropriately, and don’t be too concerned with proportions; it would take a very high concentration of H2O2 to hurt your plants.
Water your plants as you normally would, using the hydrogen peroxide solution and taking care to get good coverage of the entire top layer of soil. Use a spray bottle if desired. The soil will fizz for a few minutes after application; this is natural. The gnat larvae die on contact with the H2O2. After a few minutes the fizzing stops and the H2O2 breaks down into oxygen molecules (which your plants don’t mind) and water molecules (which your plants love).
Fungus gnat control made easy
Congratulations! You’ve just successfully treated your fungus gnat infestation. Monitor the gnat population for a few days with sticky cards, in order to make sure you’ve got them all.

Is fungus knat control well using Hydrogen peroxide?
Upon entering the water of oxygen to the soil effervescence happens and separated into two parts: part water and part oxygen, oxygen into the soil is not desirable and may kill the plant inside the the planting pot, so you should avoid adding a larger than recommended quantities.
Just make sure you buy pure H2O2 with no chemical additives! Hydrogen peroxide is often sold as a topical disinfectant, and things that are good for your wounds may not be so healthy for your plants.
