Peppermint Castile Soap Insect Spray
From the new card deck, Eco-Clean Deck, 50 Recipes for Nontoxic Household Cleaners, by Annie B. Bond
For most garden pests you don’t need much more than soap to kill pests, but make sure not to use more than directed or you can kill the plant. Soap works as an insecticide by dehydrating the insects. I particularly like this formula because it is straightforward, safe, and simple. You can make a bigger batch, but don’t add more than 2 tablespoons of soap to a gallon of water.
