Garden pests are a major problem for all gardeners, but especially for those gardeners who want to keep their gardens organic. If you have a problem with insects, but don’t want to resort to using potentially dangerous pesticides, you may struggle to cope with the infestation.

However, this excellent post will teach you how to make your own garlic and mint garden insect spray. And this one really works! Sadly, there are many recipes for organic pest control available that simply don’t work. But this one does! And there’s a handy video to show you just how to make it.

Homemade Garlic-Mint Garden Insect Spray


  • 2 whole heads garlic, cloves separated and peeled
  • 3 c. mint leaves (and stems, too)
  • 2 tsp. dry cayenne pepper
  • 12 c. water
  • 2 small squirts of biodegradable dishwashing liquid


  • Add the garlic and mint to a food processor and pulse for a few seconds.
  • Transfer mixture to a large pot and add the cayenne and 12c. water.
  • Bring to a boil; remove from heat and let sit overnight.
  • Strain into a couple spray bottles (or gallon garden sprayer) and add the two small squirts of dish soap.

To use it:

  • Shake well before each use.
  • This mainly repels bugs, though if they rub against it, it can kill them.
  • Spray all the leaves on affected plants, including the undersides – preferably on a cloudy day so as not to burn the plants.
  • Wait a few days to see the affect and then apply more if needed.
