Make Your Own Insecticide
Red pepper spray is a good general insecticide and is especially effective against caterpillars. You’ll have to use this homemade spray more often than a chemical spray, but it’s much gentler on the environment. For your own safety, wear gloves when handling peppers and pepper spray.
