To make your soap spray insecticide, mix one and one-half teaspoons of a light liquid soap with one quart of water and spray the mixture on the surfaces of pest-infested plants.
A soap spray works in the same way as an oil spray pesticide and can be sprayed as necessary. It is advisable to spray it in the evenings or early mornings rather than the hot sunny part of the day.
3. Neem oil
It is a type of oil extracted from the seeds of the neem tree. It has a natural insecticide component that can disrupt the life cycle of insects at all stages (adult, larvae, and egg), making it a great insecticide for any gardener.
Neem oil serves as an antifeedant for insects that feed on leaves and other plant parts. It is biodegradable, non-toxic to living organisms, and works against various common garden insect pests.
To use neem oil as an insecticide, start with a mixture of two teaspoons of neem oil and one teaspoon of light liquid soap. Put a quart of water on the mixture and shake it thoroughly.
Neem oil can also be used as a natural fungicide capable of combating powdery mildew and other fungal infections found on plants. Neem oil can also be sprayed on leaves to prevent plants from being ravaged by pests before they get infested.
