Organic Pest Control Garden Spray Recipe
Recipe type: Garden/DIY
Serves: 1 gallon
  • 1 medium onion
  • 4 cloves garlic
  • 2 cups mint leaves OR 20 drops peppermint essential oil
  • 2 tablespoons cayenne pepper
  • 2 tablespoons liquid castile soap (like this) (or biodegradable liquid dish soap like this)
  • Water
  1. Place the onion, garlic, peppermint, and cayenne in a blender, and pulverize it.
  2. Allow the mixture to soak/steep for a couple hours (optional, but do it if you can), then strain with a fine mesh strainer.
  3. Add the onion/garlic mixture to a one-gallon contain (an old milk jug or vinegar jug will work), add the soap, and enough water to make one gallon.
  4. Pour into a spray bottle and spritz on any plants being attacked by bugs.
  5. Spray 1-2 times per week, or after a heavy rain.
