Organic Baking Soda DIY Pesticide

Baking soda is a good all natural pesticide because it is inexpensive, smells nice, and kills pests on contact. When baking soda is mixed with water, a foaming action occurs that allows it to reach nooks and crannies in your garden. It degrades into carbon dioxide, which is odourless and non-toxic. It works well on killing aphids, mites, and whiteflies on vegetables and flowers.

Homemade Insecticidal Soap

Insecticidal soap is easy to make and effective.

Caution: Never use soap for this recipe on edible plants.


  • 2 tablespoons insecticidal soap
  • 1 cup water

Some recipes call for adding 1 teaspoon of one of the following:

  • Neem oil
  • Garlic powder
  • Lemon juice

Researchers from the University of California at Berkeley (UCB) say soapy water is just as effective as chemical based insecticides at killing pests, and natural soap is a lot safer for your plants and the environment.

Neem Oil Recipe

Neem oil is derived from the fruit of the Azadirachta indica tree. This tree is native to northern India. Neem oil is extracted from the seeds, leaves, and branches of this aza-relate tree. It is one of the most effective and affordable compounds being used today and with some simple recipe changes you can be using this compound for your garden as well!


  • 1 Part Neem Oil
  • 1 Part Citric Acid
  • 2 Part Heinz White Vinegar
  • 1 Part Water


In a spray bottle, mix the water and white vinegar together. Allow for this mixture to set for 10 minutes. Add the neem oil to the water mixture. After the solution has been mixed together, add the citric acid to the mixture. Fill the remaining amount of the spray bottle with the pH-neutral water. Make sure the bottle is not shaking, as you will need to keep this solution stable. Shake, as needed and spray for pests.

Spray once every 7-10 days.

Safety Precautions:

Diatomaceous Earth

Diatomaceous earth, also called DE, is a naturally occurring siliceous sedimentary rock. It is formed of the fossilized remains of diatoms, a type of hard-shelled algae.

Diatoms are microscopic unicellular algae that live in both fresh water and salt water. These organisms are single-celled and have a cell wall made of silica.

Diatomaceous earth is finely ground, so you can dust it into your garden without killing your plants. It works by sticking to the exoskeleton of insects and aiding in their dehydration, but your plants won’t be affected by a light coating.

To use diatomaceous earth in your garden, simply dust a light coating of it over the top of the soil where you have seen signs of caterpillars, ant hills, or other insects. You can also make your own pest spray by combining one part diatomaceous earth with ten parts water, adding a few drops of peppermint oil, and spraying on affected plants.
