Fungus gnats are tiny flying insects found in plants, soil, and potted plants. While they are generally harmless to humans, they can be a nuisance in the garden or home.
Usually they are a sign that the soil is staying too moist, too often and needs to dry out a bit more between watering.
Sticky strips capture adult fungus gnats and help to control them but don't fully eradicate them.
Sticky strips can help to stop fungus gnats by trapping the adults as they fly around. The strips will attract and trap the gnats so they can no longer reproduce. This method is most effective when used in combination with other methods such as reducing moisture levels and removing sources of food and breeding sites.
Hydrogen peroxide is an easy and natural way to get rid of fungus gnats
Instructions: Mix 1 part hydrogen peroxide to every 4 parts water and water your plants after letting the top two inches of soil dry out.
How this works:
Hydrogen peroxide is a naturally occurring compound of two hydrogens and two oxygen atoms. It is often found in nature but can also be manufactured. It is a versatile chemical used in many beneficial ways, including eliminating fungus gnats.
Hydrogen peroxide is an easy solution when it comes to eliminating fungus gnats. It is safe to use around plants and animals and won’t damage the environment.
The peroxide reacts with the organic matter in the soil and increase the acidity levels, making it difficult for the fungus gnats to survive. Additionally, hydrogen peroxide acts as an insecticide, killing the fungus gnats on contact.
To get rid of fungus gnats, mix a solution of one part hydrogen peroxide with four parts water. Pour the mixture onto the soil around the infested plant. The peroxide will help to kill the fungus gnats and prevent them from returning.
The downside of using Hydrogen peroxide to eliminate fungus gats
The only downside with the solution is that it can kill off some beneficial bacteria that may be in your soil. This isn't a big issue if you use natural fertilizers like worm castings or Bios nutrients to replenish your soil
