If you find any insects or bugs on your vegetables you may need to get rid of them right away. Unfortunately, chemical pesticides will seep in to the vegetables. You don't want to eat the pesticide, so it is best to stick with a natural solution. Orange oil--as well as any other citrus oil--is excellent for using as a pesticide. It repels bugs and insects but isn't harmful to humans or pets when sprayed on your vegetables.
Place 3 tbsp. of liquid organic Castile soap in a garden sprayer. If this product isn't available locally, you can get it online.
Add 1 oz. of orange oil and a gallon of water to the garden sprayer.
Shake the garden sprayer to combine the three ingredients.
Pressurize the garden sprayer by pulling the pump up and down and begin spraying the vegetables with your homemade orange oil pesticide. You should begin to see results immediately.
