Avoid anti-bacterial, scented, and other specialized soaps, since these may damage your plants. Dawn and castile soap are both great choices. Measure out both ingredients and pour them into a large bowl. Use either canola or vegetable cooking oil for best results. Stir the ingredients well to mix them thoroughly. Use a funnel to easily transfer the mixture into the spray bottle. Give the mixture another vigorous shake once you get it inside the bottle. If the section of the plant you test the spray on wilts or changes color, try using a different soap for this pesticide or another type of pesticide. If you tested your solution and it did not cause any harm to your plant, spray it around your entire plant, including the undersides of leaves. Focus on areas where pests lay their eggs, since an oil spray is designed to target eggs and immature bugs. Use the spray during the early morning or late afternoon, since direct sunlight could burn your plants after using oil.
