I'm located in South Africa, and would like to use JHS. However, I don't have access to Jerusalem Artichoke, Gingko, or KPFR. What can I use as a substitute? I'm having problems with looper caterpillars and cutworms.
Hello! I have done research on killing caterpillars. Mugwort JHS works great, however you can use, rosemary, mint, chili peppers, coffee beans and leaves, purslane, castor plant, and marigolds! There's also a book 100 herbs for Jadam pesticides that gives other substitutes.
