Green Bugs on Knock Out® Roses: Identification & Systemic Treatment

Thousands of bright green bugs on your Knock Outs after winter pruning? Aphids or leafhoppers — but treatment is the same.

Knock Out Reality

Disease-resistant ≠ insect-proof. They're still delicious to bugs.

Systemic Insecticide = Best Solution

• Bayer Rose & Flower Insect Control (imidacloprid) — soil drench, 6-8 week protection
• Ortho Orthenex (acephate) — spray, systemic + contact
• Both low environmental impact when used per label

Critical Step: Treat the Soil

Insects lay eggs at base. Drench soil around each plant — kills emerging nymphs.

Organic Alternative

Insecticidal soap or neem oil — spray weekly, cover undersides. More labor, less residual.

Your Knock Outs will shrug this off with proper treatment.
