The best home-made insecticide and repellent for cannabis is organic and can be made easily with groceries.

One of the most difficult issues in cannabis cultivation is the pests and insects that infest your precious garden. But you do not necessarily want to buy commercially bought products to repel them - and you do not have to, nor do you want to do it ... Insecticides and repellents are usually toxic. Here's where to start to make the best insecticide and home repellent.

Best pest sprays for cannabis.

Most homemade insecticides for cannabis use ingredients that you already have in your kitchen, such as soap, garlic, chili powder and oil.

These DIY sprays will help you rid your garden of pests such as aphids, mites, whiteflies and beetles.

Oil-based insecticides

Oil-based insecticides for cannabis are made by combining vegetable oil, such as rapeseed, soybean or cotton oil with other ingredients.

An oil-based spray works by stifling the pores of insects such as aphids and mites.


  • 1 cup of oil
  • 1 spoonful of Marseille or Castile soap
  • 1 pint of water

Recipe :

  • Mix 1 cup of oil with 1 tablespoon of Marseille soap mix well
  • Take 2 tablespoons of mixture and dilute it in 1 liter of water
  • Put in a spray bottle and apply on your cannabis

Essential oils

You can also try spraying essential oils like eucalyptus, rosemary, lemon and cinnamon. Just mix them, dilute them with water and spray them directly on your plants.

Other growers prefer to apply other essential oils such as cinnamon, clove or cilantro directly to cannabis leaves to repel pests. These oils can be used safely on cannabis plants.

However, it is recommended that you do not apply essential oils directly to your buds, as they may alter the flavor of your herb.

Soap organic insecticide

Soap insecticide is very similar to oil-based insecticides, soap-based insecticides are made by simple combination of soap and water, without oil.

It can be sprayed on your plants at any time, but it is recommended to apply it at dawn or dusk.

Soap insecticides are excellent for killing whiteflies, mites and beetles.


  • 1 ½ tablespoon mild soap like Castile soap (or Marseille soap) and 1 pint of water

Recipe :

  • Mix soap and water.
  • Put in a spray bottle and apply directly to the plants.

Garlic insecticide

Although garlic does not exactly kill insects, it is an excellent insect repellent, and it is also a great way to slow down or prevent infestations.


  • 2 whole garlic cloves (no pods)
  • ½ cup of vegetable oil
  • 1 teaspoon of mild soap
  • 2 liters of water

Recipe :

  • Purée the garlic bulbs with a little water.
  • Leave the garlic mashed overnight

  • Mix garlic with ½ cup vegetable oil, 1 c. sweet soap and 1 liter of water.
  • Remove 1 cup from the mixture and mix with another pint of water.

Chili repellent (chili pepper)

Chili, like garlic, is also a natural insect repellent. Although the pepper does not kill the insects, it discourages them, slows them down or prevents an infestation.


  • ½ cup fresh peppers or 1 tablespoon chili powder
  • Liquid soap, like Castile or Marseille soap
  • 1 pint of water M

Recipe :

  • Reduce hot peppers in 1 cup of water

Instructions for use of the powdered repellent for chili

  • Put the mixture in a spray bottle and apply directly to the plants.

Insecticide made from tomato leaves

Tomatoes are part of the family of plants that contain alkaloids that can be harmful to insects. Therefore, the leaves of a tomato plant can be used as an insect repellent, just like garlic and chilli. In fact, these alkaloids are especially effective at keeping aphids and other insects away from your weed.

Recipe :

  • Mix 1 tablespoon powder with a few drops of soap and 1 liter of water
  • Put the mixture in a spray bottle and apply directly to the plants.
