A Simple Insecticide Without Any Chemicals
To repel spiders, aphids, and other insect pests in the garden, consider this all-natural insecticide made with Castile soap. It’s a genius recipe.
Made with olive oil, Castile soap originated more than a thousand years; the Crusaders are thought to have introduced it to Europe as early as the 11th century. You can use it to wash dishes, to launder clothes, to clean the house—and as an all-natural insecticide in the garden. Bea Johnson, author of Zero Waste Home, shares her recipe:

- Liquid Castile soap, such as Organic Unscented Castile Soap; $15.29 fo 32 ounces from Vitamin Shoppe.
