5 ways to get rid of Fungus Gnat naturally
1-Disinfect the soil to kill Fungus Gnat
To disinfect your soil, you must first moisten it and place it in black or clear plastic. Then place in a sunny place for 4 to 6 weeks. The thickness of your soil should not be more than 20 cm.
Quarantine newly purchased plants for a few days before entering the house.
3-Use sand to stop female from laying eggs
This insect usually lays eggs half a centimeter deep in the soil. You can pour about one centimeter of sand on the bottom of the pot.
Because the sand dries quickly, the female thinks the soil is dry and does not lay eggs.
Oxygenated water can be used in combination with 1: 4 water (ie mix one part 3% hydrogen peroxide with four parts water). Then irrigate your contaminated culture medium with this solution.
These insects spawn the most in humid environments. So never over-water to kill Fungus Gnat. Try to choose a pot that has good drainage.
Before planting the plant in the bottom of your pot, you can first put pebbles or mineral pumice and then pour soil on it. This will make it easier for water to escape from the bottom of the pot.
Also, avoid materials such as moss in your pot that cause water to accumulate. This will help you to get rid of Fungus Gnat.
