Use a spray bottle to thoroughly soak the infected plants. Make sure to get the undersides of the leaves. Spray once a week or after it rains. Hydrogen peroxide both treats and further prevents pest infestation.
Hydrogen peroxide, well known as an ingredient in disinfectant products, is now also approved for controlling microbial pests on crops growing indoors and outdoors, and on certain crops after harvest.
Mix up a solution of 1 part pure hydrogen peroxide (with no additives) to 4-5 parts water. Mix well and water the plant, making sure to thoroughly drench all parts of the soil. The hydrogen peroxide will fizz; that's what kills the larvae and the eggs. Repeat in 2 weeks for a larger pot; in 7-10 days for a small pot.
If you use a higher concentration of hydrogen peroxide on the foliage of the plant you run the risk of burning it. You could burn the roots, but since it's necessary to kill the root rot-causing bacteria, it's a risk worth taking.
Spray your plants' foliage once per week if you're using hydrogen peroxide as a preventive. If your garden already has bugs, you may need to use hydrogen peroxide two or three times per week to get rid of them. You should also apply the spray after it rains, as the showers will wash off any spray you have applied.
Water with a hydrogen peroxide solution
To use hydrogen peroxide on your plants, combine three parts water with one part 3% hydrogen peroxide. Not only will the disinfectant properties of the hydrogen peroxide kill any bugs and their larvae, but also add oxygen to the soil to promote healthy root growth.
Step 1: Mix one part of hydrogen peroxide and four parts of water in a spray bottle. Step 2: Lightly spray the plant leaves and stems where the adult fungus gnats are visible. Step 3: Repeat as needed until the adults are no longer visible.
Controlling the dust mites in your home is the key
Using hydrogen peroxide 3% is a non-toxic, environmentally-friendly, and inexpensive way to rid of these pests. It's an easy solution that has a big impact.
When using hydrogen peroxide for plants, the solution is generally diluted, making it safe for roots. To make a safe hydrogen peroxide mixture, start by mixing 1 part hydrogen peroxide with 9 parts water. Next, soak the roots in the solution for 30 minutes.
Dilute 2.5ml hydrogen peroxide and 3 drops of neem oil to a 7500ml spray bottle to spray leaves. 2.5ml ammonia and 2.5ml neem oil once a week for pest control in spray bottle.
Treat the soil.
Use 1-2 tablespoons of hydrogen peroxide per cup of water, and mix enough to saturate the entire root ball. Mix well, then apply to the soil. Hydrogen peroxide is root safe though it can look a little scary, because it will begin to bubble up when poured in. This is normal!
For planted seedlings: Spray with H2O2 solution of 1 part H2O2 3% to 32 parts water (eg: around 30mls per 1 litre - measuring cup recommended). For established plants: Mix 1:1 ratio of 3% H2O2 and water (eg: 1 cup of each). Bottom or top water as usual (water soil only, do not pour on leaves).
Permethrin is a synthetic pyrethroid similar to naturally occurring pyrethrins which are extracts from the chrysanthemum flower. Permethrin is safe and effective when used as directed. Permethrin kills the scabies mite and eggs.
Essential oils contain compounds that repel or kill insects, including dust mites. The best essential oils for getting rid of dust mites are clove, rosemary, and eucalyptus oil. Add 20 drops of oil to four ounces of witch hazel, and spray your mattress, couch, drapes, and other dust mite hangouts.
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.
To use neem oil as a homemade bug spray mix one to two tablespoons of pure, cold-pressed neem oil, at Walmart, with a gallon of water. You can also add one to two teaspoons of dish soap to the mix to help the neem oil adhere to the plants. Alternatively, you can use neem oil as a root soak to treat root rot.
Hydrogen Peroxide (H2O2) must be diluted for safe use. To dilute to a 3% solution use 1 part 12% food grade Hydrogen Peroxide to 3 parts distilled water. For example, to make 400ml of 3% H2O2, use 100ml of 12% H2O2 with 300ml of distilled water.
The most common cause of fungus gnats in plants is overwatering, so be sure to let your soil dry out in between waterings as often as possible.
Hydrogen peroxide is one of the more affordable ways to whiten your teeth as many people have it in their homes.
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
