Controlling 'Susie Beetles' Eating Black-Eyed Susan Petals

Small Black Beetle Destroys Blooms

The beetle consumes flower petals, leaving a deformed knob. No common name—I call them "Susie beetles."

Control

• Organic: Spinosad (spray now in July, repeat in two weeks; next year start early May).
• Conventional: Any garden insecticide on same schedule.
