Question From: E. Kliem - Framingham, Massachusetts, United States
Q: Neighbors zinnias have tiny caterpillars in the cone of flower. The cones then turn black. Remedy to prevent this or at least kill them with spray.
Bonide's Captain Jack's Dead Bug Brew ( Spinosad ) will kill them on contact. Use it at sundown or just at sunup when the pollinators are still sleeping. . Best And Happy Yardening, Nancy
