How to Make Natural Pesticide

Every vegie garden is going to come across some unwanted pests from time to time.

But if you don’t want to pump harmful chemical insecticides on your fruit and veg, here’s Paul West’s recipe for an organic natural pesticide you can make at home.


  • 2 Brown onions
  • 2 cloves of garlic
  • Handful hot chillies (the hotter the better)
  • 1 litre soapy water (natural biodegradable soap)


  1. Finely slice the onion and put into a large mixing bowl.
  2. Chop the chillies and add to the onion.
  3. Peel and finely slice the garlic and add to the onion and chillies.
  4. Pour the soapy water into the bowl with all the ingredients so that they are covered. You might not need the entire litre of water. Then, allow the mixture to steep overnight.
  5. The next day, strain the liquid from the mixture into large spray container and dilute with a further 2 and a half litres of fresh water. The leftover onion, chilli and garlic can be added to your compost.

Your natural insecticide is now ready for use on the garden and is a good all round insecticide. The benefits of using natural insecticides are numerous. Here’s just a few: 

  • No harmful chemicals on your food means you and your family aren’t ingesting the chemicals when you harvest and eat your fruit and vegies.
  • It’s much more cost effective than buying chemical insecticides.
  • No chemicals are getting into your soil and there won’t be any chemical run off into drains and water ways.
  • You’re doing your bit to keep a healthy environment.
