Neem oil is a natural pesticide extracted from the neem tree, Azadirachta indica. It is a mixture of different compounds, including azadirachtin, which is the most active ingredient. Neem oil works by disrupting the hormones and lifecycle of insects, making it difficult for them to feed, grow, and reproduce. It can also kill some insects outright.
Neem oil is a broad-spectrum pesticide, meaning it can be used to control a wide variety of insects, including aphids, whiteflies, scale, mealybugs, spider mites, beetles, moths, and caterpillars. It is also effective against some fungi and nematodes.
Neem oil is considered to be a safe and environmentally friendly pesticide. It is not harmful to humans or animals, and it breaks down quickly in the environment. However, it is important to use neem oil correctly to avoid damaging your plants.
To make a neem oil pesticide, you will need:
- 1 tablespoon of neem oil
- 1 teaspoon of liquid soap or mild detergent
- 1 gallon of water
Mix the neem oil, soap, and water together in a spray bottle. Shake well to combine. Apply the spray to the affected plants, making sure to get the undersides of the leaves as well. Repeat the application every 7-10 days until the pests are gone.
Here are some tips for using neem oil pesticide:
- Apply the spray in the morning or evening when the sun is not as strong.
