When treating for bagworms, Hi-Yield Bug Blaster Bifenthrin 2.4% is more for treating trees and shrubs where they are more commonly found. It is labeled to be used around a foundation for other pests and will help to kill any that contact a treated surface, including bagworms if present. When you are treating for bagworms, apply when larvae begin to hatch and spray larvae directly. Application when larvae are young will be most effective. Once bagworms have formed their bag they are pretty protected and chemical applications will not be effective. You will need to physically remove the bags manually or with a power washer.
