Using Natural Insect Repellents
There are several natural insect repellents that often kill cankerworms on contact, but also serves as a repellent by creating a bad taste for the critter and make it go someplace else to munch. Neem Oil Soap, Hot Pepper Wax, and Garlic Barrier all have this potential repellent capability when applied properly on the tops and the bottoms of leaves of the target plant. The repelling effect will last for several weeks to a month depending on the weather conditions. See the Natural Repellents in Yardener's Tool Shed.
